Press fit vs Threaded is a selling point for me. It's the first detail I look at when considering a bike. I will ALWAYS go for the threaded bb.

@gmbntech 6 жыл бұрын

It's such a small factor (from the outside) and it seems such a dealbreaker for some. Super interesting!

@antoinedoinell 6 жыл бұрын

Yes, very small but so important for me. I like doing my own maintenance, don't like creaking and don't want to buy more specialty tools. That tolerance will eventually fade and the bike will be worthless. It's what my brain thinks. I mean let's be real...is the slight bit of extra width that much better for the consumer? or is the majority of benefit going to production costs? just my 2 cents. (THANK YOU SANTA CRUZ!)

@boomerangfreak 6 жыл бұрын

I see why people think that way really, maybe it's partly because people in general are reluctant to change? I mean how long has the BSA standard been around for now? If I can I'll go for a BSA BB myself but I won't let a good deal on a bike pass by just cause it has a PF BB. I got my scott genius for a few months now and haven't noticed any problems and in the shop I worked there most people never said anything bad about their PF BB we installed.

Since then I pay attention to my friends bikes and some of them creak and they just don't care, but they have the problem. Now, my current bikes have threaded bb and no one creaks.

When you took the cup out and noticed it was dry - That's why I do a fresh install when I get a new bike, bb, headset, even hub bearings. Sometimes they come improperly assembled - dry bearings, dry pressfits, no loctite, wrong torques. loctite 609 and 638 are good to have. Also, even thought the bearings feel good, might as well pop the seal, flush, replace the grease. Grease is a solvent and you don't know how "full" it is unless you look at it.

I know it's recommended to always store a torque wrench with it at the lowest setting but does this also apply to a Park ATD? I assume it does and always set mine to 4Nm after use but I can't find anything to confirm it online. I could just ask Park of course but I figure you'll know this and the answer may help more than just myself.

Problems I see with press fit bearings in bb shell & integrated headsets is they eat away the frame. I think I sohudl go with Chris king pressfit headset & threaded BB. So far I got good experience with it, I usually notice wear of headset bearings after few months, or weeks with other bearings I tried. the worst experience ever was FSA bearings on my fuel ex, on one bike the top bearing was crushed after just few weeks, metal shavings every where. since then I swapped for enduro & cane Creek bearings. but one one bike it wore faster than the other, maybe the frame has something to do with it, it also got a inwards dent, although it did not have an impact. I will also stay away from carbon frames.

@connriverdesign6708 6 жыл бұрын

No grease on the axle before reassembly, I usually grease the axle and inside the seals? Also, what are your thoughts on praxis or wheels mfg threaded press fit bb’s? I’ve generally replaced with one of these after a bit (or first creak) and use grease instead of assembly compound. Just curious on what you think.

Hi Doddy, Love the channel. I probably seen most of it since I came across you guys. Now during the forced holidays I decided to resume my XC bike build I was postponing for a while now, so I'm 100% ready when we're free to leave the house :) Ive seen hundreds of videos on bike and new tech which keeps changing every year. I got a great deal on barely used 29er with SRAM Eagle 1x12 drive and decent air fork. Frame I got is Merida Big9 7000, which I'll use to transfer the components to. Issues I'm having is to decide on proper spacers for DUB PF BB92. Second issue is the headset which is FSA NO.55E (company web specs) but I have issue finding it here in Australia. Is there other headsets I can use? I'm confused with so many options. Apologies if my questions seem trivial, it is my first bike build this century and so much has changed. Your channel is amazing and helps so much. Thank you guys. #AskGMBNTech

I’m thinking about leaving the Cervélo brand just because of all the headache about loctite, special tools, adapters, and chances of damaging the frame. It seems that a threaded bottom bracket would be much cheaper to service and Shimano does the Ultegra/DuraAce threaded bottom brackets as well. Haven’t installed the Ultegra Di2 kit yet, and although I bought the bike at a bike shop, I want to do the upgrade myself (or go with a cheaper mechanic).

What if with the specialist tool, there is no movement of the press fit?! The pressfit is mounted in an aluminium Cube Mtb frame. The crankset itself was already covered with a lot of "dirt" (rusty looking fat, earth...) The specialist tool slips from time to time when you are hammering to try to get the press fit bottom bracket out. No succes so far, I let it rest a night after spraying it with degreasing/cleaning product. I hope this will help. But some extra tips would be handy!

Hi, I just installed my pressfit BB86 with resing cups (Shimano BB-RS500) for the first time inside my bare carbon shell. Is it normal for the resing cups (or bare carbon) to snap/click loud like this when pressing in ? I was afraid I am damaging something ( I was using a home made press tool) but I ensured that the cups were prefitted parallel to the shell axis. I also lubricated both the cups and the shell with a little bit of waterproof grease. I think that even though the grease has been applied, the cups were sort of 'tension jumping' due to the friction with carbon but I want to make sure that this snapping noise is normal for bare carbon shells. can you advise ?
