Installing A Creak Free Press Fit Bottom Bracket | Wheels Manufacturing Thread Together PF92 BB86

[@JimGrahamNH]

Absolutely excellent! THANK YOU! First time I've replaced a bottom bracket, and this took all my trepidation away. Very clear, easy to follow. And so glad I went with the thread together vs press fit.

[@maris6843]

Very thorough video. I'm doing my first bike build, and I was confused about the thread together bottom bracket, but you cleared it up. Wheels Manufacturing seems to be a great choice.

[@Jamesthebikeguy]

Glad it was helpful!

[@ederler1129]

Thanks for the excellent video. Just got one of these installed on a bike that I previously had lots of problems with and the BB shell had some grooves from the plastic cups spinning and moving. So far no noise or issues from the wheels BB. I had decided to never buy a frame again with a press fit BB, but this BB seems to solve that issue.

[@Jamesthebikeguy]

Glad you are having good luck with this BB. They seem to fix the problems with PF and a year into having this BB I still love it.

[@Gizmoimages]

Yeah when I look for frames I look for non-PF bottom bracket frames.

[@gervasebarnes]

Good video. I like this idea. Press fit "with" the extra insurance of the thread to hold it in

[@pierrex3226]

Super helpful thank you. I have a MOQUAI BB, BB386, for Shimano spindles (24mm), works the same way. The long part goes on the right (drive side, DS), the short part goes on the NDS. I used a similar tool to press the DS cup, then a 3d printed part i found on thingiverse to screw in & press in the NDS cup into the DS cup. It went on super smooth, i've never installed a BB before, and it took me a grand total of 5min. I used lithium grease everywhere because that's what i have and i don't ride in the wet. Frame is velobuild GF002.

[@away69]

Thanks, I've bought a "BBB BottomFit BB86/92 BB-029" also threaded but UK made to replace my Shimano plastic press-fit BB that used to creak louder than my grandad's knee. Slightly cheaper than the Wheels Manufacturing version and on sale, fingers crossed it's any good.

[@ryant75]

Cool video! I wanted to add that i love mine too. It really is a great bottom bracket bearing set up. I am used same bb on on my Colnago Prestige CX. The Dura Ace wasn't creaking but it was starting to bind and has more friction. I used the wrench, homemade press tool and park tool green grease. Ride on and stay safe ✌

[@dskordo]

Hi James. Thanks for posting. This looks like a Bb86? Looking at the wheels mfg website, the instructions show the female threaded cup should go on the drive side and not the non-drive side as demonstrated. Am I seeing this incorrectly? Does it even matter?

You may be biased, but ill ask anyway. I have a yeti sb6 with a bb86/92. The weak point of the whole bike is the bottom bracket. It inevitably starts creaking and making terrible grinding sounds.

On an English threaded bottom bracket frame I had the threads fail and used a Sunlite thread-less repair bottom bracket cartridge. It was nicely made and easy to install. But I like this one in that it has the outboard bearings. Will this BB-86 also work as a thread-less repair unit or does Wheels Manufacturing make something else for those situations?

[@tatangsm09]

It becomes easier to install the BB into the shell, and press it from either side using the proper tool of press fit BB. It's really helpfull video. Thanks so much.

[@DKF22]

I'm surprised this was mentioned, but perhaps putting bb in the freezer overnight will help relieve the pressure while you thread it in.

[@Hard_Work_Is_Rewarding]

Hi, thanks for a nice video. Some questions: 1. What is the benefit and why would you replace prefectly working (no creeks, misalignment or bearing wear) plastic BB cups with this aluminium design? 2. What is the benefit of pressing in one part, whilst one could just put both parts in and push them in by threading without the press?.. 3. Does the manufacturer not give the torque numbers for this threaded connection? 4. No washer between the frame and BB, a concern for frame damage?.. 5. How does one replace bearings in this? Thanks

[@Jamesthebikeguy]

1. What is the benefit and why would you replace prefectly working (no creeks, misalignment or bearing wear) plastic BB cups with this aluminium design? No benefit to replace a "perfectly working" bottom bracket. But once your current BB wears out, then you have the ability to install once, and then just replace bearings. Piece of mind that the BB is solid and will not walk out in the future 2. What is the benefit of pressing in one part, whilst one could just put both parts in and push them in by threading without the press?.. That a hughe amount of force that would be applied to fine alloy threads. By pressing in (1) side first you legitimately reduce the load by over half compared to threading both in at once. 3. Does the manufacturer not give the torque numbers for this threaded connection? PF BBs are interference fit, so no torque specs would not be reliable on a interference fit of any kind. 4. No washer between the frame and BB, a concern for frame damage?.. Washers are for spacing, not frame protection. Some cases you need them depending on the spec of the frame 5. How does one replace bearings in this? Hammer and a punch, just like a BB30 bottom bracket

[@Wroe]

[@adamthomaes]

Great video, thanks for the walk through. I have done the same install (BB92 into carbon shell) and I am finding the lack of free-spinning after crank install a bit concerning. I don't want to destroy my BB just by going for a ride. Is this stiffness normal for a new BB thread-together install?

[@Jamesthebikeguy]

If there is significant drag I am guessing you need to adjust the spacing. Otherwise if it is minor that is likely due to the double sealed bearings.

[@timtaylor9590]

remove your bearing seals see if that helps, make sure the plastic spacers arent rubbing either, also try playing with the tension screw

[@andyp5194]

Is there an alternative wrench that can be used?

[@captaincommodore8901]

I bought one myself but I wondered about the "wiggle" room between the threads of the male and female part that allows an offset of about 1-2° if the frame is not perfectly made. And the lower quality ABEC 3 for the price.

A creaking bottom bracket is the absolute worst!!!!

[@chrishammond7632]

@@Jamesthebikeguy Knocking out the bearing with a punch is effective, but not a great idea. Walking the bearing out with a punch does damage to the walls of the cup and promotes creaking in the future. Much better to press the bearing out or hammer it out straight with a dowel or PVC pipe or something else.

[@cliffcox7643]

Questions. Im about to buy, ...why NOT retaining compound? wont' retaining compound absolutely stop any creak... Second, still loving it?

[@bitmadmax]

Well firstly, in their instructions WM say using retaining compound will void the warranty. As there is friction between the races being a pressfit AND cups are threaded tightly together retaining compound isn't needed. It may also make removing the cups more difficult in future if you need to. To reduce the chance of creaking make sure the shell is spotless and use a compatible grease on the threads and the faces.

Do the spacers go on the outside of the dust cap if needed? why would i need them?

Yep they go on the outside. Inbetween the cap and the crank. You would need them as some cranks/frames have different tolerances causing you to need to adjust the fit so that you do not have lateral play

Any 16-notch 48.5mm bottom bracket wrench should work. Looks like Park and a few others make it too. Your BBT-9 is a 44mm 16-notch so it does not fit (Thats a Shimano standard) so likely would need another tool

My new problem will be to take out that crank spindle. I hope with time they loosen if not I’m doomed. Any thoughts or advice? Thanks.

[@dansburns]

Nice, well shot and informative review. However, this seems to be a solution for people who used a wood block and mallet to install their BBs and then wonder how or why they creak. They creak because you didn't put them in properly and they messed up the BB shell and nothing will sit flush again. Use the right tool in a slow methodical fashion and they seat straight every time. I've never....knock on wood...had an issue with PF BB.

[@Jamesthebikeguy]

I partially agree with you. Yes a ton of people install PF bottom brackets wrong. Unfortunately about as many manufacturers cannot get their factories to make a round hole to tolerance. This fixes both of those conditions!

non contact seals are the only option, the plastic spacers are bad and create possible drag from contact on the shields/seals. metal spacers are best to ensure contact is only with the inner race part of the bearings. besides that thicker grease can slow down a free spin too but not by much when merely observing. all that said theres no good reason why a crank should not spin freely as the sealed cartridge bb's have done decades ago. i mean they said man went on the moon but we since lost that tech and cant do it today as easily, did we also lose the tech of a free spinning bb or are we all just enjoying the cool-aid while coming out of pocket more than ever

sorry but you said go ahead and leave a comment.. When you were putting the drive side in, it didn't seem to meet the frame very square at all and when you finished them cranks wouldn't spin!

BB looks quality I must say but I wouldn't be happy with that friction personally..

[@Jamesthebikeguy]

I just re-watched the install part of this video and I am not seeing what you are talking about regarding the BB not installing square. The BB was installed flush against the frame, and the crank spindle slid in w/o the need of a hammer. Those are generally very good indicators that the BB is aligned well enough. The "stiffness" you might be seeing is due to this being a BB designed for a mountain bike. Inside the bottom bracket, it is using an Enduro bearing with a dual Labyrinth seal . These seals are a little draggy but trade some friction for protection against water and dirt ingress. On a mountain bike this is crucial for longevity. Sure its not going to win a crank spinning contest but who needs to? If you were building a road bike that was never going to see water a totally different bearing setup would be in order. On a mountain bike its a great choice.

[@spongeyspongey5983]

@@Jamesthebikeguy when you put the drive side in, it looked like it was closer to the bottom than the top, this isn't a problem with your bb by the way, it would be the fact that few frames are made to a close enough tolerance in the bb area.. however, it would distort an inferior bb. I see what you are saying about the seals but it would annoy me.., the bearings are fully sealed from factory so , I understand you don't want grit in between bearing and crank but I don't feel it needs to be that tight? maybe it is just the video but when you are attempting to spin or turn the crank it is moving the entire bike?.. still looks like a nice product to be fair x

[@danfuerthgillis4483]

The issue with Threaded vs Press fit started because the morons at Cannondale were stupid idiots with BB30. Instead of calling for the bearings to be unified together from end to end inside a shell they cut cost and have the bearings just press fit into the frame. Manufacturers then started to make the frames and then since the tolerances were never enforced by Cannondale most if not all frames were not made to proper specs to fit the bearing under pressure. Some frames the bearing just slided right in with no pressure. Also with Carbon making a perfect round hole is not that simple. With a threaded BB shell like Alloy or Steel there is no issue with this as both cup bearings are unified end to end on the same shell. This is why there are metal inserts that you can add to BB30 shells so that you can then press fit standalone bearings into that shell. Wheels Manufacturing, FSA, Hambini, ZTTO or get the Press fit-threaded BB which is basically what Cannondale should of made when they came up with the BB30 standard. PF30 was a better system but still had some issues with size tolerances. BB386 unifies a universal system so that it can use almost any cranks mix mash. So if you do get press fit then get BB386.
