Scotty was great at the maintenance videos, but Doddy is even better IMO. The guy clearly knows his stuff, and he seems really natural on camera. Loving him as a new presenter so far.
This is the first media video I have heard someone actually recommend retaining compound (i.e. Loctite 640), which works excellent for aluminum shells. This guy knows what he's talking about!
good video. but should mention to viewers about the plastic piece between the left crank arm pinch bolts, it needs to flip up before the crank can come off. Really looking forward to more tech videos by Doddy!
A tip that might help when removing the cranks: you should loosen the bolts evenly, otherwise one gets loose and the other gets extremy tight, so better slowly each one a bit at a time.
Wow, thats not as bad as I thought, same with your servicing your forks video. Thanks Doddy, I'm slowly growing in confidence to do more of my own maintenance. Hopefully that'll help me enjoy the riding time even more! Cheers, Ben
I was sceptical of press fit BB's til I got my Trek Stache with a press fit. Just replaced one after 2 years and probably around 5 to 6 thousand miles. I have to laugh when people say that threaded BB's are so much better. Well they creaked a shit load too! Headsets have used press fits for ever. And with threaded BB's you can get BB's to seize so bad that you can't remove them.
What is an anti-creak compound for carbon frames? Not fiber grip, right? Wheels Manuf recommends dry or a compatible grease for carbon BB shells. Thanks.
Doddy forgot to explain the function of the lttle plastic lip on the left crank. He had to lift it up before removing the crank with the mallet. No big thing but essential.
What is not mentioned here is how the crank mates to the inner bearing surface in BB's of this type. This is a basic question beyond the scope of this video, but I would like to know what video if any answers it. In general it appears to me that the outer surce of the bearing is mated to the shell either by friction or by being screwed in....but no one clearly states how the inner surface of the bearings are mated to the crank and/or pedals.
I don't understand press fit, is it just cheaper than having threaded bb shells? been watching a lot of GMBN videos its nice to see the old MBUK guys .
hi, can somebody tell me what is the name of the Red aluminum part that says GENIUS 22 30Tthat looks like a cover to keep the frame from any damage with the chain.... TKS
A road bike? What kind of a hippster are you. This might be suitable for work, but don't show up dressed like this in the woods, you would make a foul out of yourself.
I have installed a new press fit BB from shimano (XTR level) into my alloy frame with the help of one of those dedicated press tools and used some amount of Lactite 648 retaining compound to stop it from moving and creaking. I rode my bike only two days later, so there were plenty of time for the retaining compound to dry. It didn't help, however. The bike is creakier than it was. It creaks when I pedal under load, but also when the bike is standing and I put pressure on it by leaning on it from above. And it does not matter if I lean onto the saddle or onto the top frame tube. I am now wondering, what if I bought an expensive metallic BB such as Token Ninja which threads together, spend about 100 euros and the BB would still creak. Looks like there is no panacea from those creaks at all. Thinking about selling the bike and building a new one myself with a threaded BB...
Great video! Installing my first PF BB into a new carbon frame - should there be the occasional creak along the as your getting close? Had around 15mm left to go. Thanks.
Hey guys, I have a problem: I just bought a new xt chain, and the Dartmoor simple chain keeper, The problem is the chain keeper just tensions the chin downside, so at woody sections, the chain just pops at first teeth out of sprocket, so when I crank forwards, it pops just right out. The sprocket looks ok, at some teeth a bit sharp, cause of the slipping. Any suggestions to get more tension or without buying a new chain guide ? Thanks, Greetings from Germany!
some old bikes with sealed square taper bottom bracket are still going smooth after hours and hours of riding. i also love thick chains, soft hardtail frames, coil spring forks...nicely padded saddles, 32 spokes, upright riding position....aaahhhhhhh nowdays with super steep seat angles and super stiff race frames my knees hurts after 3-hour riding. (i'm 21 yrs old)
#ASKGMBN We will be driving to Sweden this year with the car and I want to take my bike and my brothers bike with me. We will drive more than 20 hours. How can I Protect the bikes from any damage and rain ? (The bikes are on a bike stand for cars)
Buy some fat bike tire tubes and trim them to fit your frame, put some plastic shopping bags over your handles to cover shifters n stuff where water could get into cable housings
Just buy a regular motorcycle cover, if the bikes are close enough, one could do but then you'd maybe have to cut holes and put some plastic bags to cover the handlebars
Car Guy I would never put a loose cover on anything at highway speed, it will destroy the surface underneath through a combination of road grit and constant flapping. Bicycle, motorcycle, it's the same thing, don't do it.
I have no idea how that flapping could damage it. Sure amybe with sand and other junk inside but these are easy ways to avoid that. Also it will just stick to it like your shirt to your chest when cycling.
Well the easiest way is not to do it. You'll never see a motorcycle being transported with a cover on it travelling down the highway. If you've ever seen someone towing a load with a loose tarp flapping wildly, it is similar to that as not all surfaces and edges can be kept taut, it's really brutal on paintwork.
I have a Sram PF BB30 and I REALLY, I mean REALLY struggle to get those crank arms off.. Basically I have to undo a bolt (drive side) that's tightened at 54 Nm.. I've tried all my best, even put on it 70-80Kg on it to undo it but still nothing.. It makes a terrible sound and I want to clean it up (I know how) but I can't get those cranks off.. Suggestions?
I had to cut my crank arms of one time because I had the same problem. Next time you put some on make sure to put that special grease on it (not sure what it's called, it's blue). The same goes for the pedals. These parts get tighter over time, so the 54 Nm wouldn't be enough to loosen your cranks anymore.
I managed to do it once by myself.. Then I tried it again 6 months later and nothing.. Took it to Specialized dealer.. now after just 2 months of normal riding (I have an enduro bike and still don't have the opportunity to go out on the real trails so I'm stuck at street riding and just be creative) it's dirty and starts to creak a lot.. If I clean the bike, it stays quiet for 2-3km and then starts to get noisy again...
For those not wanting to splash out for a rather pricey bearing press tool, I made my own fairly similar to this: forums.mtbr.com/drivetrain-shifters-derailleurs-cranks/diy-bearing-cup-press-tool-%245-press-fit-bottom-bracket-pics-922442.html Might isn't even as good or refined as that and it works pretty nicely.
hey guys !! i need your help and get an advice from yu experts as you can see im a newbie here and i wanna buy a Mbike !! i live in belgium and i have a low budget from 450 tot 500 euro and i wanna buy a Mbike for crosscountry !! im in front of 2 choices teh first is an (Cube aim pro 2017) and the second is an (Orbea Mx50 2017) whish one tne best do you think ? and should i have a 27.5" bike or 29" size wheel ?? thanks for responding as soon as possible !! (Note: pls don't advice me to pick a SCOTT ihave no enougth money to pick an expensive bike ! )
I don't think I'm a fan of press fit bb . good old threaded for me. if it ain't broke don't change it. my Norco 250 is press fit and I totally hate that bb.
I have a BB like this on my CX bike it comes loose on a regular basis though i got both frame and several expensive BBs new. This is a total bullshit system if it does not even work on a CX bike then i don´t even want to try a MTB with pressfit BBs. Even in my LBS they told me that theyhave nothing but problems with these most people buying a bike with pressfit BBs come back to them pretty soon because it either creeks or comes loose and deforms. I won´t be buying any frame using one of these anymore for sure.
bitumen83 I wouldn't say a bad invention, but it should've been replaced w threaded on all high end bikes by now.... why are some companies switching BACK to press fit? I'm shopping for a new bike, but everything i like turns out to be press fit! Dammit!!!
@@Dude-Smellmyhelmet yeah I like the press fit that has a shell that threads into itself it’s very good but all other press guy’s I’ve used gave me problems over time so always get the ones that thread into them self’s in the frame and you should be dialed!
Step 1: Realize that you spent money on the wrong bike because that is exactly what you did wrong. Step 2: Throw the bike away or sell it to someone who doesn't know a thing about bikes. Step 3: Buy a bike with a threaded bottom bracket. QED

Ya he's prolly best maintenance presenter I've seen, not just on GMBN either
Very good video, perfectly natural and understandable. Thumbs up Doddy!
Plus Scotty never rocked the jorts!
I defiantly agree!!
This is the first media video I have heard someone actually recommend retaining compound (i.e. Loctite 640), which works excellent for aluminum shells. This guy knows what he's talking about!
I was thiking the same! event thoug park tool has a retaining compound, i always wonder why no one mentions it
Fyi, Loctite 641 or 609 are designed specifically for press fit applications
I always fix a creaky PFBB by buying a new frame with a threaded BB....... Works every single time.
ThunderStruckCoach XD
best bike comment in the internet
And that's why you live in a cardboard box
Agreed, press fit sucks.
Doddy really comes across calm and professional in his instructions. Great presenter.
Best one i saw till now. Showing everything in as much detail as is needed - no more no less. Good job.
good video. but should mention to viewers about the plastic piece between the left crank arm pinch bolts, it needs to flip up before the crank can come off. Really looking forward to more tech videos by Doddy!
Great job on your first mechanical video Doddy!
Blake getting a free BB service by Doddy, lucky Bing Bong !
video comes to the right time,guys. my new bike with pressfit bb will arrive in two weeks. great job,doddy

ive had issues for bloody months with my BB (ISIS) absolute shite had to get an upgrade... luckily on warranty!

This video was long overdue. Thanks for posting.
I used a headset press to install the BB bearings into the frame of my Fat bike. Worked a treat :-)!
So clear and informative thanks Doddy.
Clear, concise and to the point. Thanks!
Theres should be a plastic plate between the pinch bolts that hinders you to punch the arm out?
you guys are awesome and inspiring
The TROLL what
Hi, aren't you missing a spacer on the drive side? Have a look at 3:31 and then at 6:04.
Best way to prevent BB creak, don't buy press fit BB.
BB30 is stiffer but crank options are not there.
Very well explained by an obviously very competent rider.
we would like to see Doddy shred some trails 😁
Great video. Can you show how to replace the bearings in your rear hub?
I think tech videos are better with you on board! PS: how often should I clean my bottom bracket ?
What is an anti-creak compound for carbon frames? Not fiber grip, right? Wheels Manuf recommends dry or a compatible grease for carbon BB shells. Thanks.
pretty cool video. really helped keep up the good work
Awesome video Doddy!!
Can you guys do a video for installing a iscg05 adapter with the press fit bottom bracket? Haven't seen any on TH-cam
Doddy forgot to explain the function of the lttle plastic lip on the left crank. He had to lift it up before removing the crank with the mallet. No big thing but essential.
Links to the tools used in this video would be extremely helpful.

at 6:00 any pointers on how hard to tighten the bottom bracket installer tool? As hard as it goes or just until it sits firmly?
great video - really good detail!
Nice vid dodo😊
I don't understand press fit, is it just cheaper than having threaded bb shells? been watching a lot of GMBN videos its nice to see the old MBUK guys .
thank you for the help will try it
Press Fit is the worst! never gonna buy a Bike with Press fit again. But good video, really like the new presenter.
Really nice video👍
Doddy !!! Cool man you know whats what ...
hi, can somebody tell me what is the name of the Red aluminum part that says GENIUS 22 30Tthat looks like a cover to keep the frame from any damage with the chain.... TKS
love gmbn
Can you make a vid on HOLO TEC bottom bracket
Hopefully this solves my problem. I actually have the same bike lol
It should well do then!
Once removed you have to replace with a brand new one or cleaning and reassembling is just fine?
hi and every one have an amazing day 😀😀😀😀😀
Doddy's brilliant at this :)
Scotty,What would you recommend to remove a stuck PF bottom bracket?
Is it ok to wear a full face helmet while wearing a trail bike for the sake of making an edit? Or would a half shell make more sense.
CrazyKidGamer66 wear it for safety!
I'd say wearing a trailbike is so strange by itself, it doesn't matter wich helm you put on your head.
I wear a trail bike with cowboy boots and a belt. It's a little tight in the crotch, though, so I usually wear a road bike.
A road bike? What kind of a hippster are you. This might be suitable for work, but don't show up dressed like this in the woods, you would make a foul out of yourself.
it might be doable if you have hairy legs otherwise I would go for a bmx
Is there a way to get the plastic ring off without the tool ? 1:50
Finger nails should do it. If not try scissors. Slide them in & then open them up so they fit into the notches

Will one tool work for removal of both 30mm and 24mm spindle?
I've never owned a bike with a press fit BB. Is there any advantage to these over threaded in bearing cups?
If you've ever made popcorn and thought, "I'd like to hear that when I pedal", then yes.
They're cheaper for manufacturers to install without any detrimental effect to performance...except when it comes to maintaining them. Ugghh.
YES if you're lookin for a loud creaky bike that needs twice the BB maintenance
how do you do to find out what press fit bb your bike's instaled with? i've looked everywere on the bb and on the bike's spec list but nothing...
Very well explained!
Thanks
Great video! Installing my first PF BB into a new carbon frame - should there be the occasional creak along the as your getting close? Had around 15mm left to go. Thanks.

threaded bb are better
Can i put deore or slx crank or any crank in pressfit bb
Thanks Doddy! this really helped :)
shimano anti seize vs. carbon paste (mucoff) on a carbon frame with pressfit bb - good idea?
you got me thinking about press fit vs threaded bb. what is better? (a question for ask gmbn plz)

If I want to convert this PF30 to a BSA, I have to change the cranks, right?
Yeah, the axle for PF30 is bigger. BSA is 24mm axle.
Shit.. Does it cost a lot to replace it? (I have carbon cranks in good shape, I might be able to sell them)
You forgot to undo the safety plastic in the left crank arm. Actually, by using that mallet you might have damaged it.
#askGMBN Where does Doddy come from? Like is he a pro bike mechanic or a racer?
Taking driving test today. Wish me luck
Gl, just drive like you were instructed to :D
KD Outdoors who needs to drive when you can bike
Stevo Daniels you right
KD Outdoors but good luck then you can drive yourself to The trailhead.
Steven Daniels that’s one of the main reasons I wanted my licenses so I can go hit the trail when ever I want. Btw I passed
Wait hold up was it just me or was everything ungreased when you reinstalled it?

Finally
Could just install a new bottom bracket considering they're only 25 bucks for the nylon
The amount of times he said "compound", i think there needs to be a compound counter

Good cat, here's a mouse 🐭
He says thank you.
You're not supposed to reuse Shimano pressfit bearings.
Craig Jervis I would suggest not using them in the first place
Step 1: Realize that you spent money on the wrong bike because that is exactly what you did wrong.
Step 2: Throw the bike away or sell it to someone who doesn't know a thing about bikes.
Step 3: Buy a bike with a threaded bottom bracket.
