Your cart is empty.The BB30 bottom bracket system uses a 68mm (road) or 73mm (MTB) wide shell and a 30mm diameter crank spindle. The frame's bottom bracket shell itself is not threaded; instead the bearings press directly into the frame. BB30 frame shell inner diameter is 42mm, has two bearing retaining clips and two 6806 bearings pressed directly in the shell. The BB30 system uses thin spacers and/or a wave washer between the bearings and the crank arms to take up any slack and micro-adjust the chainline of the crank.

I replaced my stock BB in 2016 (2 years and approximately 5000 miles) with Wheel Manufacturing BB30. Now 8 years and 14k miles later, replaced it again. Better than stock.

Fairly basic. They were the right size and equal to the ones I installed previously

I have a 2013 Orbea I recently purchased used with Dura Ace 9000. The original BB sounded kind of noisy when I did an overhaul after purchase about 6 months ago. A few weeks ago I noticed it was "wiggling" pretty severely I looked at the numbers on the side of the bearings and it matched this one. This one DID come with the c-clips needed to correctly install. Installation was as easy as is possible with BB30. The noise and wiggle are gone. The only reason for marking down to 4 stars is this seems like a lot of $ for two bearings and c-clips. NOTE: I really strongly recommend buying a proper BB30 installation/extraction tool if you don't have one. I purchased a fairly cheap one on Amazon for about $30.00. This is a job you really can't do properly without the right tools without risking damage to an expensive frame.

Worked great for my Cannondale Fat Caad. Glad it came with clips, as my new frame did not.

I've been using these for three BB30 bottom brackets. All are still spinning after thousands of miles. They pressed in nicely and spin smoothly.

Pretty easy install (does require the proper tools). Good longevity since I was replacing the same product that I installed on this bike 8 years ago and I wasn't mortified by the old bearings when I removed them.

Needed to replace the BB on my Felt CX bike and these things went in very easily and after 6 months or so of abuse, they still spin with very little drag. Don't waste your money on ceramic.

Very smooth and they fit perfectly in my PF30 BB. I have only ridden on them a few times so far so I don't know about how long they will last, but very happy so far.
