Very pure engineering solution. Nice way to avoid bearing alignment difficulties, just a small weight sacrifice over carbon monocoque, and the custom geometry is a great perk. Carbon tubing also much much cheaper than laid up prepreg or infusing your own complex shapes.

i am familiar with additive manufacturing of metals. Have you tested this joint for fatigue? additive metals tend to be much weaker in fatigue when compared to more classical methods. Additive creates micro voids and cracks in the part. Good luck
Being primarily a mountain biker, it makes you realise just how overpriced road bikes are. I still wouldn't buy a bike that doesn't have a lifetime warranty on it though and made by a company that honours that i.e. Santa Cruz.
I think it’s because mtb doesn’t exactly offer “super light” tiers like S-works or hi-mod. If we look at the base models prices for frames, they do kind of match road bikes. For example, my Switchblade2020 frame retails for roughly 6k sgd with a fork. That puts it in the same ballpark range as my Tarmac SL7. So, I don’t think that road bikes are overpriced if you look at it relatively to mtbs. It’s just a few people who keep singing the same tune over and over again, which in a echo room starts to sound like it’s true, but not when you look at it with reference to other fields.
@@87togabito There are literally S-Works and Hi-Mod mtb frames though? Also comparing a rigid road fork to an mtb suspension one is not fair. Suspension forks are a lot more complex.
@@87togabito Of cause MTB manufacturers offer super light bikes. Many brands have their lightweight carbon versions as opposed to their standard carbon models. MTB forks and road forks aren't really comparable and most MTB frames come with pivots. linkages, bearings, shock etc.
@@PeakTorque you pay for Engineering more than the materials actually and I think it is harder to design a road bike than a mountain bike since UCI rules have to much bullshit on Roadbike design than Mountainbikes.Imagine a F1 Mercedes team spend millions for Engineering and how much trial and error plus paying riders to test and paying people to create something fast like Trek bikes was one of top tier on Engineering like so competitive they always sure their athletes get the best bike on the events compared to small company who have very little engineering budget instead they just buy pre made frames in China and stick their brand there
I hope the bonding is better than on my 1993 Trek 2300. The glue unfortunately was the weak spot and the frame started to disintegrate. Frame looks slack but it’s fine for a downhill bike. Do you have some geometry data for us. What head angle 📐 is that? Anyway hope you will have a fun time on your new bike. Still mixed emotions using carbon fibre on a „rowdy bike“. Weight shouldn’t be the decisive factor on such a bike so I tend to stick with aluminium there. Maybe I just crash too much…
Speaking of centering of the rotors, do any rotors (6 bolt) AND hubs even provide a centering feature? I sincerely doubt it. I just preload it rotationally and center them that way.
Sometimes. I seem to remember a Magura rotor and Magura branded DT hub centered itself. There was a ring built into the hub shell that mated to the inner edge of the bolt holes on the rotor.
The fact that it's 3D printed and hand made in the 'west' for the money is quite amazing. As for the means of manufacturing, I think it's probably the easiest way of making completely custom geometry, even easier than having a welded metal frame (considering the jigs that would be required for that). Would it be possible to use aluminium tubes in this case as well? Would the weight be a big negative? One thing to note, does it really have to have 6 links? What's the benefit of having two links by the BB?
@@jfcote42 not one as complicated as for welding if you want to hold it in place when tacking the parts. Or at least you don't need to straighten the frame after gluing, like you do after welding. Plus the heat treatment, etc.
No, not if you want long continous fibres like we have in normal carbon fibre cloths. You can injection mould or 3d print chopped/short strand carbon fibre reinforced plastic but you don't really have control over fibre orientation, and the part will be a LOT heavier for the same stiffness/strength.
Interesting would be a 3 D printed Aluminum frame, with a sort of aluminum foam inside the tubes and a hard shell at the outside, the design how bones work.
Always wondering why no "modern" road bike goes back to round tubes + lugs construction? It should be cheaper, less void, although heavier, isn't a sounding structure more important than the marketing bs?
@@larslosh5598 depends on how the lugs were made. 3D printing, hardly. Casting/stamping/etc., maybe. It would, if nothing else, be a less energy intensive process as you don't need to weld or put the tooling with the frame into an autoclave.
@@larslosh5598 If go round tubes, there are tons of pre-built tubes, thus can be cheaper. And round carbon tubes are much easier to build, less void. For lugs, I'm not sure if carbon lugs will be cheaper than the current method, but if go alloy + casting, it should be cheaper.
I think that triplebutted aluminium tubes with smooth welds are superior design in bike manufacturing. Cheap, lightweight, durable and repairable. I wouldn't trust heterogennous glue bonds on anything than road bike, especially on DH! And in terms of weight, check weight of aluminium and carbon framesets of Trek's Checkpoint. They are almost the same but the price slightly differs...
Aluminum is not as repairable as you think. Also there is nothing inherently wrong with this joining method. It's used in aerospace and if it's well designed it can be extremely durable
Do people think "glue" means Elmer's? There are airplanes with parts glued together under stresses far greater and with orders of magnitide more use-hours. But no concern there.
@@conman1395 Do you mean carbon fiber-resin matrix or something different? Can you show (name) me some examples, please? And of course airplanes structure is under greater stresses than bike, it is constructued with much lower safety coefficients, because in aerospace engineering every gram matters. Do you really want to compare multi-billion aerospace industry with bike manufacturing? Do you think Trek, Merida or Canyon have army of engineers who are able to model every possible scenario of strain?
@@kosskrit like you wrote, aerospace grade carbon fiber is still something different from industrial grade carbon fiber , the fibers have more strength and there are numerous different sorts of resin depending on the purpose and the temperatures it has to withstand. Both (metal and CFK) will work on a bicycle (they would not sell these bikes if they would fail in general), at the end metal is sufficient for most riders and much less labor intensive in manufacturing. Aluminum frame production can use lot more automation compared to carbon fiber which is mostly hand labor
Seems like a nice bike, but I am not a fan of internal routing. But this bike has alot of great features. I did not know it had replecable brake threads. I have that on my bike, but it's a Nicolai/Geometron. Only few brands have this feature, I see Crossworx ha sit too, another brand too but forgot the name.
This is the standard way to set brakes up for the UK and Ireland and for all motorbikes, so if you ride motorbikes (Left lever is the clutch) and bicycles it makes even more sense to do this regardless of where you live. Since the front brake is where the vast majority of stopping force comes from, it makes perfect sense to put the front brake on the right side as most people are right handed and have better grip strength on their right hand as a result, giving the best chance possible of emergency stops being successful. Putting the brakes the other way stinks of someone who knows nothing about bicycle physics making the rule up with no consultation from cyclists as they're more afraid of people using the front brake without weight shifting backwards first and sending themselves over the handlebars than they are about every bike user having less effective stopping - it's probably the earliest use of the 'think of the children' justification for making bad rules I'm aware of.
I always thought it was to do with hand signals. Driving on the right one uses your left hand to signal and so the rear brake is on the right; if driving on the left then hand signals are made with the right hand and so the rear brake is on the right. Motorbikes are the same worldwide and the front brake on the right is same side as throttle so you cannot accelerate and brake at the same time.
@@JohnPilling25 Where I live bicycle hand signals are made with the arm on whichever side you're planning to turn to. For cars and trucks, where the driver can't stick their hand out the passenger side window, a turn towards the passenger side of the vehicle is indicated by holding your arm out the window with the elbow bent 90 degrees, fingers pointed upwards and hand open with palm forwards though. Having the front brake and rear derailleur both at my right hand is very useful indeed when I have a shopping bag hanging on the left side of the bars or when I'm transporting a second bike by holding it at the stem and rolling it beside me while cycling my own bike though.
Seen someone on Reddit making these types of frames too. Think his company is called BMK? Seems like Bastion are getting competition, which is good for us mortals
Not gonna lie, is still very expensive but you get way more that what you pay for compared with other bike manufacturers, specially considering is a custom size bike frame. Way better value than Bastion that's for sure.
I don't know how he managed to focus on the build with you there, offering advice and bad jokes! LOL The bike looks great, but there has to be a better colour choice for the grips, which match absolutely nothing. Cheers!
I have been hoping for the last 4 years for manufacturers - particularly of gravel and all-road bikes - to incorporate 3D-printed titanium lugs (and some other tech, such as Z-couplers for splittable frames) into their bikes. I'm sick and tired of hideous welds, plain cylindrical cross-section metal tubing and absolute disasters of bike transport both by train and airplane.
The real mystery is why floating calipers where half as many pistons will give the same power at a lighter weight and with potentially better cooling. The Magura Gustav from back in the day was outrageously powerful for its time and is the last floating caliper brake I'm aware of. The MT7 that fills that niche from Magura currently is a great brake too though - it uses magnets to hold the pads, so no spring snagging the rotor when the pads get a bit worn and none of the rattling you get when you remove the spring either.
I like the frame construction, but damn, those angles… I’m an old geezer, I still ride my ‘94 mtb, fully rigid, and coming from that, these modern bikes look clownesk. That head angle is so flat, it looks like the frame broke. His knees hardly clear the handlebars… not my cup of tea.
With all that money spent at least get a competent mechanic, what happened with the starnut, that stem cap didn't look that central and you don't need to keep taking off the cranks to space the chain guide and a guess you didn't have any hose cutters. Most of that was hard to watch.

Putting the brakes the other way stinks of someone who knows nothing about bicycle physics making the rule up with no consultation from cyclists as they're more afraid of people using the front brake without weight shifting backwards first and sending themselves over the handlebars than they are about every bike user having less effective stopping - it's probably the earliest use of the 'think of the children' justification for making bad rules I'm aware of.
@@peglor very well explaind...thanks for schooling me👍
I always thought it was to do with hand signals. Driving on the right one uses your left hand to signal and so the rear brake is on the right; if driving on the left then hand signals are made with the right hand and so the rear brake is on the right. Motorbikes are the same worldwide and the front brake on the right is same side as throttle so you cannot accelerate and brake at the same time.
@@JohnPilling25 Where I live bicycle hand signals are made with the arm on whichever side you're planning to turn to. For cars and trucks, where the driver can't stick their hand out the passenger side window, a turn towards the passenger side of the vehicle is indicated by holding your arm out the window with the elbow bent 90 degrees, fingers pointed upwards and hand open with palm forwards though.
Having the front brake and rear derailleur both at my right hand is very useful indeed when I have a shopping bag hanging on the left side of the bars or when I'm transporting a second bike by holding it at the stem and rolling it beside me while cycling my own bike though.
why there were NO aero ANALisis?
Seen someone on Reddit making these types of frames too. Think his company is called BMK? Seems like Bastion are getting competition, which is good for us mortals
Nice build 👌🏻
Not gonna lie, is still very expensive but you get way more that what you pay for compared with other bike manufacturers, specially considering is a custom size bike frame.
Way better value than Bastion that's for sure.
A perfect example of internal routing being a pain in the ass.
I don't know how he managed to focus on the build with you there, offering advice and bad jokes! LOL The bike looks great, but there has to be a better colour choice for the grips, which match absolutely nothing. Cheers!
They matched the mossy wall... details
A) green sets of orange beautifully
Or
B) finding components is like finding rocking horse excrement at the moment.
Hint - it's not completely A
wow! don't know who the hell is that guy, but he bought pretty top spec build with freaking Athertons frame to do some 2ft parking drops! Stocked!
Really really cool!
If ever you need another double-entendre Finbar I'll give you one. 😉🤣
Why are you installing the star nut without the rest of the fork? It isn't that hard to install in a fork. Emphasis on the word fork.
I have been hoping for the last 4 years for manufacturers - particularly of gravel and all-road bikes - to incorporate 3D-printed titanium lugs (and some other tech, such as Z-couplers for splittable frames) into their bikes. I'm sick and tired of hideous welds, plain cylindrical cross-section metal tubing and absolute disasters of bike transport both by train and airplane.
I want the bike
None of this "Dream Bike Build "Edited stuff ,how my bike builds usually go , parts and tools everywhere , few accidents along the way
Wish they made road bikes.
nice build but cables are much to long.
seriously trick build!!
How people still don’t use floating rotors is a mystery
The guy in this video has been using hope floating rotors for ages but said they slight movements just actually caused more rub and ticking
The real mystery is why floating calipers where half as many pistons will give the same power at a lighter weight and with potentially better cooling. The Magura Gustav from back in the day was outrageously powerful for its time and is the last floating caliper brake I'm aware of. The MT7 that fills that niche from Magura currently is a great brake too though - it uses magnets to hold the pads, so no spring snagging the rotor when the pads get a bit worn and none of the rattling you get when you remove the spring either.
I'd have gone for a DVO fork . It's a bit heavier but stronger .
Orange color hubs is better than red. 😅
I like the frame construction, but damn, those angles… I’m an old geezer, I still ride my ‘94 mtb, fully rigid, and coming from that, these modern bikes look clownesk. That head angle is so flat, it looks like the frame broke. His knees hardly clear the handlebars… not my cup of tea.
The sheer amount of shit talking and childish innuendo was brilliant.
Who is suing you out of curiosity?
Who is this cowboy.
With all that money spent at least get a competent mechanic, what happened with the starnut, that stem cap didn't look that central and you don't need to keep taking off the cranks to space the chain guide and a guess you didn't have any hose cutters. Most of that was hard to watch.
Of course everything was fine, there was just a lot of jesting and piss taking.
nice to see like a true engineer your humour is degenerate XD
this gotta be the most ghetto workshop aka office, such a bike has ever been built up in. Makes me nervous for some reason.
Sexy sexy bikes. I want one with a motor mount, not a bottom bracket..
jeesus, will you cut your nails? :D
Bush mechanics lol
Ooo er missus.
pure filth ;)
14.40 " you'd have to be pretty effin stupid not to do it 180"
Remember the Royal Navy recruiting advert "if you can fix a bike you can fix a ....."
The lad fixing the bike has the cranks not at 180 🤣
Yep. That was pure comedy gold when he did that, not even scripted
A poor workman blames his tools, but in this case the tool didn't hold the other side where I thought he was.....
