"Free spinning = low friction " bearing is the biggest ploy companies who make them try to push onto consumers. It does not matter how they freely spin. What really matters is how they operate under real load conditions. Or another words what is their coefficient of friction under the load that the chain is exerting on them. We have done an extensive research, designed special bearings for this project, empirically tested them under the real load conditions in laboratory and we came up with a solution where actually best possible option to achieve low friction on the bearing is by greasing them with special grease. This is the reason they don't " freely spin" under hand. With our solution you get great bearing durability and low maintenance. Some other companies simply play the game of having “heavy” alloy pulley (mass) and no oil or a drop of oil in the bearing so they can spin for a long time. Our pulley rotational mass is very low which will simply not freely spin. The reality is that bearing friction is actually not very important because relatively good bearings only consume less than 0.3W (all together). The difference between best bearings is of about 0.1W. Where real gains are is the preload spring tension where we can gain 1.2W as we were able to achieve lower spring tension with our design compared to others and the fact that the pulleys are big - this is what gives you the biggest savings by reducing the angle between chain link plates during the operation hence reducing the friction on the chain. Free spin pulley or not free spin in 0 load condition is not important.
I could never spend that much money on bling. My waxed chain is quieter than even that with stock ultegra components AND it saves more watts than an OSPW could ever do. $700 is absolute insanity if it was $70-$100 may be as a way to make the bike unique but that’s just nuts

@@paulmichaelpolsinelli1945 , the bigger wheels spin faster, so fewer watts, but how many watts is the question. We need to know the benefit of the costly upgrade to make an informed decision.
@@paulmichaelpolsinelli1945 , sure, the ceramic speed oversized pulley is likely fewer watts, but at what cost? Remember, 75% of the wind drag on a bike is the rider profile, not the bike itself, so just getting more aero in position will save you dozens of watts effort. At best the ceramic speed pulley only saves you 1.3 watts, but why pay $549.00 to save a meager 1.3 watts? My aero helmet from Bontrager (Ballista) saves me 7-10 watts at 45 kph, and it only cost $139.00 on sale, a much better investment. Just compare how many watts a component offers, then compare the price, a simple ROI for an engineering mind to decide.
700 bucks !!! Good Lord Jesus…lol Thank you brother for showing reviewing this, I actually saw this before and I was curious about, I wanted to see a real world test and see what the hype was all about, you actually cleared up some of my questions, thank you bro, awesome job
@@MrTuxy Did you hear how loud the first test was with stock pulleys? Sounded like poor adjustment and then "magically" it got quieter after spending $700 plus labor ...
There is a simple test that you could do to verify the saving or otherwise for this product. Fit the bike to a smart trainer and fit a crank or pedal based power meter. Get two head units, one to read the trainer power and one to read the crank power. Warm up the trainer for 10 minutes and do a spin down. Now pedal at a steady wattage as shown at the crank for 15 minutes with the standard Shimano setup. Fit the AB pulley and repeat at the same crank watts. Calculate (Av. crank watts - Av. trainer watts) for standard setup = A. Calculate (Av. crank watts - Av. trainer watts) for AB pulley setup = B. Calculate (B - A) to give you watts saved or otherwise with AB pulley.
@@dre78 The power meter and trainer should still register a difference because they will read somewhere between -2% and +2% of actual power. But the error should be consistent if other parameters remain the same.
@@hallisoft1926 2% of 200w is already 4watts... and what if my powermeter is in the low end -2% and trainer is in the high end? If I put on the new cage and calibrate the trainer is the zero value exactly the same as with the old cage? Nah don't think that it's possible. But good luck. You could just train more better value for money than this "upgrade".
I’ll stick with my 105 for $50 😀! If I splurge for ultegra at $100 I won’t notice much difference and the money will probably fly under the radar. If I spend $700 my wife will definitely notice, be mad, and feel it justifies her spending the same on an ugly purse. So it would actually cost me double. I’ll stick with 105.
This piece of overpriced rubbish seems to have finally pushed people too far with regard to its fake claims of better performance. I have a lot more faith in the proper engineers who have exposed it for what it is. Shame as AB chainrings were pretty good, ruined their reputation overnight with this....
Products like these only exist because the are people who have more money than brains. I'm not judging, you spend your money the way you want. But I care how people perceive me.
.............. your crazy. it is a new product that I showed off and gave my thoughts on it..... just like I showed off a ceramicspeed one as well I show cool products off and by no means do I ever tell anyopne to buy anything, you are a grown man with your own money and own descensions to make in life....... no one is taking the money out of your pocket, at the end of the day i show proiducts and it is your call whether or not you want to buy this or not. simple as that
@@GCPerformance18 you basically made a comment that you felt faster and anyone who said otherwise must be negatively biased. The product is absolute crap (pun intended) as their bearing is dogshit and the amount of friction added by it completely destroys their claimed aero benefit. Also, if your concern is the noise of your drivetrain, you aren't moving fast enough to generate road or wind noise, so maybe focus on that.
Hey man I do appreciate your honesty in the reviews saying that you bought it for looks first! Still on the fence that OSPW is a waste of money, but your test definitely show that it's quiet! Would love to see an update down the road after you've ridden then more and if there's any reduction in the sound dampening.
Thanks for the video, it was nice to finally see a proper live demo of the product. I think anyone claiming to be buying these things for the "gains" is kidding themselves. Even in a world of marginal gains this is on the lower limits of it at best. You buy stuff like this for the bling and nothing else. Imo when it comes to bling, $7, $700 or $7000, if it makes you feel so much better having it that it justifies the price tag then good for you, that's just how bling works. To me personally, it looks good and it's definitely quiet, but I'd pay maybe $100-150 tops for something that did only those 2 things.
If you are claiming this and that and the other and coming out with all performance stats and figures then Hambini Will call you out on it if you are found to be not telling the exact truth
It's a cheap injection mold, not a carbon... In all respects, but materials, and the idea is crap. It's a cheap ceramic bearing probably made in Poland for 10USD.
If injection moulding carbon-reenforced plastic is sufficient, then why bother with carbon? The weight is already below the CS offering. Unfortunately neither Hambini, nor GC Performance tested this part under load, so the jury is out. Out of pure conjecture, I would guess that this part is never under any real lateral load simply because it is attached to a derailleur held in position by a spring that is trivially overpowered by the force of an off-centre chain line, so lateral stiffness probably doesn’t matter much. And forward/back stiffness probably doesn’t matter much for similar reasons.
Habbini I believe exposed the absolute and their claims. The gain from these pulleys are so little that only the pros could justify its price. We mortals could gain nothing from these gadgets. Your better off keeping your drive train clean and lubed
Questions about noise: 1. Was shifting tuned before recording with stock pulleys? 2. Was shifting re-tuned before recording with ab ospw? 3. Does noise from pulley matters more than freehub noise? Why?
yes to both shifting questions at the end of the video there is another test where I spin it again and it is more quiet, and noise does matter more then freehb noise because freehub noise only occurs when not pedaling so you cna control it but sometimes when pedaling you hear a lot of noise, it is something you might be use to but when installing this pully on the bike it was much more silent, and i knowit is not a big deal, but something cool, if you ever noticed back in the day with 9speed and 10 speed stuff it was silent and smoothh shifting that was because there was more spacing in the cassette and the chain was a little large allowing it to absorb more noise and chain rattle..... its something you probably dont know you need or want untill you experience it, by all means am I saying go out and buy this product but just remeber the first time you hear this for yourself in person from a friend or at a shop you wil be suprised how quiet the drivetrqain is
That's Great that AB is having youtube censor Hambini. It says something. If I was AB I would post a video to challenge Hambini's claims. I have a feeling AB does not have a leg to stand on. As an engineer - Hambini makes perfect sense. If I had that amount of cash hanging around I would gladly pay it to make the DA Di2 on my uber expensive bike quieter period. Forget all those aero and power claims.
Bigger bore = more frictional drag Larger surface area the less aerodynamic a product is You can calculate approximate figures for frictional torque using this simple formula: Radial ball bearings: 0.5 x 0.0015 x radial load in Newtons* x bearing bore (mm) Axial ball bearings: 0.5 x 0.0013 x axial load in Newtons* x bearing bore (mm)
those are some crazy formulas, and I dont know about the larger surface area, because like look at these climbing bikes like the sl4 which has less surface area..... compared to a shiv that has much more surface area and the shiv is more aero all day
Absolute Black is losing the plot. Loved their chainrings... After seeing this and the BS they advertising, losing all credibility with me. Im out as a customer. But there will be enough brain dead lawyers, doctors etc that will want these on their bikes and pay that kind of stupid money.
Dude, you bought one of those to put on your bike? I would not say it was for the reason it looks cool, since you work in a shop I would try to explain that it is under test. You are going to lose credibility when you try to pitch other stuff. People are going to be laughing at you man.
What do you? Lose credibility. At no point did I tell anyone to buy anything. That is for the people with there own money to make that decision. Also I got sent that out for free to show it off. My Chanel is and has never been about me telling you what to buy. It is just to show off cool things and let you make the decision if you wanna buy it or not. You don’t have to buy it, and also as much as we can sit around here and listen to one or more people say it’s crap. I am always a believer in people riding stuff and trying it for themselves, now in this case it is something that is $700 dollars so the consumer would have to see if it is worth it or not. But these prices are not new to the industry. Ceramicspeed has versions of ospw for $650 for a coated version and like $1400 in 3D printed titanium
Save your $700 money. Diet and fitness will definitely show some improvements. May take longer. But once you get there you'll know the difference and it's a lot cheaper. A life long change.
Stuff like this is bike parts for the same dudes who are willing to spend $1000 for an audio cable "because it sounds better" but really because they like what they look like.
The ONLY good thing about this crap, is that it looks super cool ! But man, 700 bucks !!!! WTF !!! Btw, everybody should watch Hambini's video on that Absolute BS !
Great stuff mate! I have this exact setup (same color even) and I can vouch for its lack of noise. The first ride I took with it I thought to myself- “man, this thing is smooth, quiet and fast”. After about ride 3 I was back to- “I’m fat, slow and weak”😂
When I am outside riding I can’t hear my Shimano 105 drive train. WTF. I don’t care if I can hear my drive train in a quiet room when I bikes on the stand.
When Absolute Black 1st bought them out l sais 2 myself, if l purchase an OSPW it would be there's. Thx U just proved on Looks alone that my judgement was spot on
I love your videos but as a mountain biker this just blows my mind. $700 gets you a decent fork or killer shock. For fucks sake it's not even a whole derailleur lmao. Road bikers are crazy man.
BTW I have sram force on my Factor 02. and initially it was noisy, way more so than the Di2 on my Tarmac. I had my LBS change out the chain rings wanted (48/35) but all they could find in 172.5 mm was Red. The difference with Red chain rings and chain is night and day. It's now Di2 quiet 🙏
No idea you did a face reveal lol. Clicked the video then when it started I thought "who the fuck is this?" Even checked if it was the same channel lol
Hambini rules. He's the best 5 year old tester out there. Absolute Black have called Hambini an "Armchair engineer " which is hard to explain how you're an armchair engineer and a manufacturer of bottom brackets as well as aerodynamics engineer. 🤔
Hahahhaha I think they should. If they are confident in the product they should have sent him one and let him review it and stand by there product. They looked real petty the way it went there
@@GCPerformance18 I couldn't agree with you more! I am super curious if Absolute Black can back up their testing claims as well as where and how they source their materials. I'll give a lot of respect to AB if they do send him a free one to take apart and review. If not I think the TH-cam community may reach out to help get Hambini the product for free. 🙏🏻🤞🏻
@@GCPerformance18 I recently got really into mechanical keyboards. At the end of your video I had to make sure it was still the same one and not a mechanical keyboard video 😂
Hey I just bought one of these but have had a nightmare trying to fit it (probably my lack of ability). I'm trying to fit it to an Ultegra Di2 derailleur, but I find that it doesn't take up the slack at all. No idea what I've done wrong but in the gears where the chain was under the proper tension I have to agree that it was super quiet and (probably placebo) did seem easier to turn the pedals. I just want to get it to fit properly so I can take it for a spin.
you probbaly have the udi2 long cage and it prob wont work with it, same thign with ceramicspeed ospw they do not work with long cage ultegra di2 derailers..... they have loose chain slack in small and small and thne when you make it taught then in bigand big it is way too short
Topic recommendation: Can you please do a video on shimano direct mount rear derailleur hanger? Such as the Sigeyi or the ones EF engineering uses? Thanks brotha, love your work
I won't fall for that overpriced 'bling' gear again. I have that Ceramic speed oversized pulley system. Apart from the looks and the loss of money it has done nothing noticeable to improve my bike riding. It's all bullshit marketing fluff for the image conscious coffeeshop rider.
yea but as long as you bought it for the reason of looks first because u wanted too, then that is alright, it is where these companies claim massive gains for no reason is the problem
Thanks GC, nice video, gr8 to see a guy talking. Agree quieter and looks the part. Saving watts? I don't thinks so. It is on the return path of the chain, therefore only to take up the excess chain due to casstte and chain ring variation, sees no load. The only load on it is the derailleur spring. Buy to look sexy. But for performance, hmmmm 🤔
It can save up to 3.5W. i will try to explain why in two parts 1) yes chain is on the return part but you forget that the chain has the be fed back to cassette from the cage. Imagine that you are pulling that chain a little backwards and when you pedal chain has to go forward hence you get some resistance. If you hold the chain below the cassette you need to overcome that force first to push forward. Now imagine you help the chain by pushing it towards the cassette from the bottom. Suddenly you dont need to overcome any resistance so you have a little gain. 2) how we can remove that resistance? In simple terms by A - reducing the cage spring tension B- by decreasing the chain links bending angle with a bigger pulleys which in turn decreases the friction on the chain itself. The less friction on the chain the less Watts lost. This is just a generalization for you to better understand where the gain comes from. We also used other tricks to reduce the friction but these are the main two components why oversized pulley wheels make more sense.
@@AbsoluteblackCc really? I agree it looks sexy and you want to compete with Ceramic speed. But come on! If you disconnect the chain from the cassette and chainrings and remove the spring tension the chain will almost fall through the pulleys on its own weight. Even if the bearings were better the difference is so small incomparision to the losses on the loaded side the difference is insignificant. It is like removing one panel bolt from a car and saying you can feel the difference. I admire you offering an alternative to ceramic speed, but they are also stretching the truth.
@@AbsoluteblackCc okay absoluteBLACK, pardon my scepticism, but we get claims like this all throughout the industry, with no supporting pier reviewed papers released. i will give you the benefit of the doubt, if you direct me to your studies/papers , showing controls and test outcomes, Plus give your product to someone like Peak Torque or Hambini to carry out independent testing. If it is all true what you say, i will make a video promoting your product and apologizing on this video for my comments here. Fair enough?
So how does it perform? Sound of silence doesn't say anything about the performance. Is the shifting better, is it holding up after 100km Rain? I would expect such for this kind of money, and more.
Just came from Hambini… As a mechanic I think you should have questioned the construction and the lack of spin on the wheels. You spent more time talking about how it looked.
yea because thats exactly what this product is... you dont buy this product because you want the 1-3 watts...... anyone buying an ospw buys it for looks first........ you as an adult can make the decision weather you have the money to buy one of these
that spin test doe.............. :)))))
When i bought absolute, there is tiny bottle oil in there
It’s 100% BS. On the other hand, it may be resistant with a free spin, but totally different under load.
The drag test maybe...no spinning with that thing.
I like to see someone replace the plastic races, metal ball bearings to a full ceramic one to see what it like

Remember, 75% of the wind drag on a bike is the rider profile, not the bike itself, so just getting more aero in position will save you dozens of watts effort. At best the ceramic speed pulley only saves you 1.3 watts, but why pay $549.00 to save a meager 1.3 watts? My aero helmet from Bontrager (Ballista) saves me 7-10 watts at 45 kph, and it only cost $139.00 on sale, a much better investment. Just compare how many watts a component offers, then compare the price, a simple ROI for an engineering mind to decide.

700 bucks !!! Good Lord Jesus…lol
Thank you brother for showing reviewing this, I actually saw this before and I was curious about, I wanted to see a real world test and see what the hype was all about, you actually cleared up some of my questions, thank you bro, awesome job
$700 for extra friction in the drive chain :)
@@MrTuxy Did you hear how loud the first test was with stock pulleys? Sounded like poor adjustment and then "magically" it got quieter after spending $700 plus labor ...
Rip anyone who buys this thinking it will make them faster.
Nice bling upgrade though!
I have strava receipts to prove it 🤑
5:10 oh shit went fancy with the sound waves!
Hahahhaha my friend
I came here after watching Hambini's video on this
There is a simple test that you could do to verify the saving or otherwise for this product. Fit the bike to a smart trainer and fit a crank or pedal based power meter. Get two head units, one to read the trainer power and one to read the crank power. Warm up the trainer for 10 minutes and do a spin down. Now pedal at a steady wattage as shown at the crank for 15 minutes with the standard Shimano setup. Fit the AB pulley and repeat at the same crank watts.
Calculate (Av. crank watts - Av. trainer watts) for standard setup = A.
Calculate (Av. crank watts - Av. trainer watts) for AB pulley setup = B.
Calculate (B - A) to give you watts saved or otherwise with AB pulley.
yes
Good luck with that if the magical saving from this product is 1 to 3 watts...... that's with the accuracy margin of the powermeter.
@@dre78 The power meter and trainer should still register a difference because they will read somewhere between -2% and +2% of actual power. But the error should be consistent if other parameters remain the same.
@@hallisoft1926 2% of 200w is already 4watts... and what if my powermeter is in the low end -2% and trainer is in the high end? If I put on the new cage and calibrate the trainer is the zero value exactly the same as with the old cage? Nah don't think that it's possible. But good luck. You could just train more better value for money than this "upgrade".
@@GCPerformance18 and evn better get different persons to ride and change the part, so the test can be blind
I’ll stick with my 105 for $50 😀! If I splurge for ultegra at $100 I won’t notice much difference and the money will probably fly under the radar. If I spend $700 my wife will definitely notice, be mad, and feel it justifies her spending the same on an ugly purse. So it would actually cost me double. I’ll stick with 105.
you can almost buy the whole 105 grpset with $700
You wife has nice hand bags.
Not to mention the 105 (empirically) outperforms the AB part, and the Ultra blows it out of the water.
Snake oil
Lmao
This piece of overpriced rubbish seems to have finally pushed people too far with regard to its fake claims of better performance.
I have a lot more faith in the proper engineers who have exposed it for what it is. Shame as AB chainrings were pretty good, ruined their reputation overnight with this....
Products like these only exist because the are people who have more money than brains. I'm not judging, you spend your money the way you want. But I care how people perceive me.
I will judge. An IQ test. If you buy one, you are a moron...lol.
Wow, I used to like your channel and bike description- but this just totally buries your credibility.
.............. your crazy. it is a new product that I showed off and gave my thoughts on it..... just like I showed off a ceramicspeed one as well I show cool products off and by no means do I ever tell anyopne to buy anything, you are a grown man with your own money and own descensions to make in life....... no one is taking the money out of your pocket, at the end of the day i show proiducts and it is your call whether or not you want to buy this or not. simple as that
@@GCPerformance18 you basically made a comment that you felt faster and anyone who said otherwise must be negatively biased.
The product is absolute crap (pun intended) as their bearing is dogshit and the amount of friction added by it completely destroys their claimed aero benefit.
Also, if your concern is the noise of your drivetrain, you aren't moving fast enough to generate road or wind noise, so maybe focus on that.
Hambini video before you waste your money.
Hey man I do appreciate your honesty in the reviews saying that you bought it for looks first! Still on the fence that OSPW is a waste of money, but your test definitely show that it's quiet! Would love to see an update down the road after you've ridden then more and if there's any reduction in the sound dampening.
Thanks for the video, it was nice to finally see a proper live demo of the product. I think anyone claiming to be buying these things for the "gains" is kidding themselves. Even in a world of marginal gains this is on the lower limits of it at best. You buy stuff like this for the bling and nothing else. Imo when it comes to bling, $7, $700 or $7000, if it makes you feel so much better having it that it justifies the price tag then good for you, that's just how bling works.
To me personally, it looks good and it's definitely quiet, but I'd pay maybe $100-150 tops for something that did only those 2 things.
All well and good with this review but having watched it, I'd say most people would get the ceramicspeed!
Well... ceramicmeme is another bullshit product.
Watch Hambini video on it. It’s an absolute garbage. Don’t waste your $$$
go watch Hambini's video on it, what a scam :O
Better check out Hambini’s analysis of these… no benefit at all and unlikely to last very long 👍
I am going to put ti through the test and install it on some bikes
Hambini did a review on it he wasn't to impressed by it
Haha that's an understatement
If you are claiming this and that and the other and coming out with all performance stats and figures then Hambini Will call you out on it if you are found to be not telling the exact truth
It's a cheap injection mold, not a carbon... In all respects, but materials, and the idea is crap. It's a cheap ceramic bearing probably made in Poland for 10USD.
If injection moulding carbon-reenforced plastic is sufficient, then why bother with carbon? The weight is already below the CS offering. Unfortunately neither Hambini, nor GC Performance tested this part under load, so the jury is out. Out of pure conjecture, I would guess that this part is never under any real lateral load simply because it is attached to a derailleur held in position by a spring that is trivially overpowered by the force of an off-centre chain line, so lateral stiffness probably doesn’t matter much. And forward/back stiffness probably doesn’t matter much for similar reasons.
Habbini I believe exposed the absolute and their claims. The gain from these pulleys are so little that only the pros could justify its price. We mortals could gain nothing from these gadgets. Your better off keeping your drive train clean and lubed
even they don't use the garbage though
Questions about noise:
1. Was shifting tuned before recording with stock pulleys?
2. Was shifting re-tuned before recording with ab ospw?
3. Does noise from pulley matters more than freehub noise? Why?
yes to both shifting questions at the end of the video there is another test where I spin it again and it is more quiet, and noise does matter more then freehb noise because freehub noise only occurs when not pedaling so you cna control it but sometimes when pedaling you hear a lot of noise, it is something you might be use to but when installing this pully on the bike it was much more silent, and i knowit is not a big deal, but something cool, if you ever noticed back in the day with 9speed and 10 speed stuff it was silent and smoothh shifting that was because there was more spacing in the cassette and the chain was a little large allowing it to absorb more noise and chain rattle..... its something you probably dont know you need or want untill you experience it, by all means am I saying go out and buy this product but just remeber the first time you hear this for yourself in person from a friend or at a shop you wil be suprised how quiet the drivetrqain is
GC Performance
Thanks for swift response!
That's Great that AB is having youtube censor Hambini. It says something. If I was AB I would post a video to challenge Hambini's claims. I have a feeling AB does not have a leg to stand on. As an engineer - Hambini makes perfect sense. If I had that amount of cash hanging around I would gladly pay it to make the DA Di2 on my uber expensive bike quieter period. Forget all those aero and power claims.
Bigger bore = more frictional drag
Larger surface area the less aerodynamic a product is
You can calculate approximate figures for frictional torque using this simple formula:
Radial ball bearings: 0.5 x 0.0015 x radial load in Newtons* x bearing bore (mm)
Axial ball bearings: 0.5 x 0.0013 x axial load in Newtons* x bearing bore (mm)
those are some crazy formulas, and I dont know about the larger surface area, because like look at these climbing bikes like the sl4 which has less surface area..... compared to a shiv that has much more surface area and the shiv is more aero all day
I have had NovaRide OSPW since March and I love it! For $200, it gets the job done and looks great. No way would I spend $700 on this one!
Its just as useful as ceramic bearings on a bicycle! People will buy it of course.
hahahahha of course doe
Absolute Black is losing the plot. Loved their chainrings... After seeing this and the BS they advertising, losing all credibility with me. Im out as a customer. But there will be enough brain dead lawyers, doctors etc that will want these on their bikes and pay that kind of stupid money.
Dude, you bought one of those to put on your bike? I would not say it was for the reason it looks cool, since you work in a shop I would try to explain that it is under test. You are going to lose credibility when you try to pitch other stuff. People are going to be laughing at you man.
What do you? Lose credibility. At no point did I tell anyone to buy anything. That is for the people with there own money to make that decision. Also I got sent that out for free to show it off. My Chanel is and has never been about me telling you what to buy. It is just to show off cool things and let you make the decision if you wanna buy it or not. You don’t have to buy it, and also as much as we can sit around here and listen to one or more people say it’s crap. I am always a believer in people riding stuff and trying it for themselves, now in this case it is something that is $700 dollars so the consumer would have to see if it is worth it or not. But these prices are not new to the industry. Ceramicspeed has versions of ospw for $650 for a coated version and like $1400 in 3D printed titanium
Lmao you've lost all credibility. Go check out Hambini and Peak Torque's video
how did I lose creditability, I never said go buy it just showing off cool items
@@GCPerformance18 it's only cool visually. It's an absolute crap in terms of functionality and performance.
Shift lag due to longer arm is baseless, because it's the smaller pulley that pulls the chain across the Cadette, so only that distance matters
Save your $700 money. Diet and fitness will definitely show some improvements. May take longer. But once you get there you'll know the difference and it's a lot cheaper. A life long change.
Stuff like this is bike parts for the same dudes who are willing to spend $1000 for an audio cable "because it sounds better" but really because they like what they look like.
lmao no lie.... its the same thing as me bulding a custom keybnoard for $600 I have keyboard for 80 btu I enjoy the sounds of my custom keeb
uh i forget what kind of material it is in there the bearing, yeah its very proprietary. LMAO
lmao it is on there website, it is like a ring of some sort
$700 shiny scam component!
it looks cool
why the video is so blurry?
The ONLY good thing about this crap, is that it looks super cool !
But man, 700 bucks !!!! WTF !!!
Btw, everybody should watch Hambini's video on that Absolute BS !
wait some weeks and buy two pairs of this ospw on ali express for $70
Absolute blackhole in my bank account.
I enjoyed this product for sure
Well worth the money if you work early mornings and don't want to wake up the neighbours pulling out of the driveway, by the SOUNDS of it ;)
hahahahhah alright that was good lol
Great stuff mate! I have this exact setup (same color even) and I can vouch for its lack of noise. The first ride I took with it I thought to myself- “man, this thing is smooth, quiet and fast”. After about ride 3 I was back to- “I’m fat, slow and weak”😂
When I am outside riding I can’t hear my Shimano 105 drive train. WTF. I don’t care if I can hear my drive train in a quiet room when I bikes on the stand.
It's great the market decides if it's a good product or not, if it's good or bad TH-cam and other social media sites will soon let you know.
I would pay double that price
It’s a gift 🎁 I’m going 60mph now
lmfao
When Absolute Black 1st bought them out l sais 2 myself, if l purchase an OSPW it would be there's. Thx U just proved on Looks alone that my judgement was spot on
I love your videos but as a mountain biker this just blows my mind. $700 gets you a decent fork or killer shock. For fucks sake it's not even a whole derailleur lmao. Road bikers are crazy man.
Totally guilty as charged !!
BTW I have sram force on my Factor 02. and initially it was noisy, way more so than the Di2 on my Tarmac. I had my LBS change out the chain rings wanted (48/35) but all they could find in 172.5 mm was Red. The difference with Red chain rings and chain is night and day. It's now Di2 quiet 🙏
I have ehard that aslo about the cassette too in the rear
3'47 "pretty smooth pretty quiet" ....yeah can't even hear it wahaha🤣
Super sprawa, tylko są dwie kwestie:
1. Cena
2. Jak w tym wymieniać kuleczka 13T ?! 🤷
I watched this video just to read the comments.
hahahha I love it
Things I don't hear while riding along, my stock Ultegra drivetrain.
Hahahahha
No idea you did a face reveal lol. Clicked the video then when it started I thought "who the fuck is this?" Even checked if it was the same channel lol
its absolute crap...
Really interested in your opinion of Hambini's absolutely reaming and Peak Torque's reviews on this🤔
Hambini rules. He's the best 5 year old tester out there. Absolute Black have called Hambini an "Armchair engineer " which is hard to explain how you're an armchair engineer and a manufacturer of bottom brackets as well as aerodynamics engineer. 🤔
You know who Absolute black WON'T give a free Hollowcage to review? #Hambini hahaha
Hahahhaha I think they should. If they are confident in the product they should have sent him one and let him review it and stand by there product. They looked real petty the way it went there
@@GCPerformance18 I couldn't agree with you more! I am super curious if Absolute Black can back up their testing claims as well as where and how they source their materials.
I'll give a lot of respect to AB if they do send him a free one to take apart and review. If not I think the TH-cam community may reach out to help get Hambini the product for free. 🙏🏻🤞🏻
I'm glad you did a some what positive video of this product. Not that I could justify $1000AUD, but still.
I really enjoyed my time with this product
so according to physics you need a small bearing and a large cog not the other way around
the looks 10/10 (imo)
the functionality ehhhhhhh/10
Looks so nice but approaching A$1000 for a OSPW is a little ridiculous. Nice rig at the end aswell GC!
I trust more in the knowledge of Hambini
$700 for that!? Placebo affect. You must be crazy!
That coiled cable has seen some better days!
Lmao
@@GCPerformance18 I recently got really into mechanical keyboards. At the end of your video I had to make sure it was still the same one and not a mechanical keyboard video 😂
Face for radio?! How dare they! Haters gone hate bro 🤣🤣
hahahaha thanks man

Lmaooo
Who would spend that on that component? Plus hambini has a pretty interesting video of this item.
I like it but I mean u hgave to have the money for it
Holy Sh*t theres a baby Groot in your computer
Lmao yes
HELLO HAMBINI FANS and welcome!
:)))
Hey I just bought one of these but have had a nightmare trying to fit it (probably my lack of ability). I'm trying to fit it to an Ultegra Di2 derailleur, but I find that it doesn't take up the slack at all. No idea what I've done wrong but in the gears where the chain was under the proper tension I have to agree that it was super quiet and (probably placebo) did seem easier to turn the pedals. I just want to get it to fit properly so I can take it for a spin.
Let us know how it performs once it got wet or dirty. Good luck!
you probbaly have the udi2 long cage and it prob wont work with it, same thign with ceramicspeed ospw they do not work with long cage ultegra di2 derailers..... they have loose chain slack in small and small and thne when you make it taught then in bigand big it is way too short
I am going to run mine for a while and see how ti goes
@@GCPerformance18 that sounds right, yet in their video it says that they are compatible
Topic recommendation: Can you please do a video on shimano direct mount rear derailleur hanger? Such as the Sigeyi or the ones EF engineering uses? Thanks brotha, love your work
Absolute scam
Holy crap that was an insane difference I bet Rides of Japan will end up getting one after this video haha
I won't fall for that overpriced 'bling' gear again. I have that Ceramic speed oversized pulley system. Apart from the looks and the loss of money it has done nothing noticeable to improve my bike riding. It's all bullshit marketing fluff for the image conscious coffeeshop rider.
yea but as long as you bought it for the reason of looks first because u wanted too, then that is alright, it is where these companies claim massive gains for no reason is the problem
If you want shiny anodised jockey wheels just get some Hope 12T.
Very nice prototype that made it into production.
Thanks GC, nice video, gr8 to see a guy talking.
Agree quieter and looks the part.
Saving watts?
I don't thinks so. It is on the return path of the chain, therefore only to take up the excess chain due to casstte and chain ring variation, sees no load.
The only load on it is the derailleur spring. Buy to look sexy. But for performance, hmmmm 🤔
Well put. I can get behind that statement. I never push these as an option to gain speed.
It can save up to 3.5W. i will try to explain why in two parts 1) yes chain is on the return part but you forget that the chain has the be fed back to cassette from the cage. Imagine that you are pulling that chain a little backwards and when you pedal chain has to go forward hence you get some resistance. If you hold the chain below the cassette you need to overcome that force first to push forward. Now imagine you help the chain by pushing it towards the cassette from the bottom. Suddenly you dont need to overcome any resistance so you have a little gain. 2) how we can remove that resistance? In simple terms by A - reducing the cage spring tension B- by decreasing the chain links bending angle with a bigger pulleys which in turn decreases the friction on the chain itself. The less friction on the chain the less Watts lost. This is just a generalization for you to better understand where the gain comes from. We also used other tricks to reduce the friction but these are the main two components why oversized pulley wheels make more sense.
@@AbsoluteblackCc really? I agree it looks sexy and you want to compete with Ceramic speed. But come on! If you disconnect the chain from the cassette and chainrings and remove the spring tension the chain will almost fall through the pulleys on its own weight. Even if the bearings were better the difference is so small incomparision to the losses on the loaded side the difference is insignificant.
It is like removing one panel bolt from a car and saying you can feel the difference.
I admire you offering an alternative to ceramic speed, but they are also stretching the truth.
@@AbsoluteblackCc okay absoluteBLACK, pardon my scepticism, but we get claims like this all throughout the industry, with no supporting pier reviewed papers released. i will give you the benefit of the doubt, if you direct me to your studies/papers , showing controls and test outcomes, Plus give your product to someone like Peak Torque or Hambini to carry out independent testing.
If it is all true what you say, i will make a video promoting your product and apologizing on this video for my comments here. Fair enough?
@@waynosfotos maybe this wasnt enough fair for them. Nice to see how the have removed the hambini videos and the non-response to this post
btw you are not riding this bike with the rear tyre mounted wrong ? check out the arrow on the sidewall just saying no offence
It is a customers bike. They mounted wrong. No offense taken
we want silent when pedaling and loud af when we coasting
So how does it perform? Sound of silence doesn't say anything about the performance. Is the shifting better, is it holding up after 100km Rain? I would expect such for this kind of money, and more.
I am going to test and find out for sure
Spend 700 bucks on any product and you will definitely "feel" the difference 😅
Feel the difference
Just came from Hambini… As a mechanic I think you should have questioned the construction and the lack of spin on the wheels. You spent more time talking about how it looked.
yea because thats exactly what this product is... you dont buy this product because you want the 1-3 watts...... anyone buying an ospw buys it for looks first........ you as an adult can make the decision weather you have the money to buy one of these
the silent part of it is crazy good for racing, people not being able to ear you shifting before an atack is a deadly combo
Dont slag them off or they will have your video banned like they did with Hambini 😂
How does the weight compare to OEM? Not another OSPW.
I believe weight of the stock one was 54g it wil always be lighter
Someone should sue them. This is an outright scam.
Where i can buy these?
any dealer around you or absolute black website
