Bb86 sram axs

Which bottom bracket do you recommend I get for my BB86 frame to fit SRAM Force crankset (FC-FRC-D1)? I couldn't find a BB86-specific DUB bracket on SRAM website but they do have a "press fit bottom bracket" (BB-DUB-PF-A1). Is that the one I want? Are there any alternatives that are compatible or is SRAM DUB BB the best value?

BB86 and Sram don't get along very well...it's a Shimano standard that was designed for 24mm spindles. In order to fit a DUB (29mm) spindle, the area between the inner and outer races of the bearings has to be very small, which leads to accelerated wear, and overall poor performance.

If you are deadset on using a DUB crank, then your BB options are limited, and your best bet would be the one from Wheels Mfg. It skips the plastic/aluminum sleeve, which allows for a slightly larger bearing OD. But, plan on having to replace it fairly often, and it will probably end up creaking...because Sram, and the inability to run a thread-together BB.

Your other option is BBInfinite. It's a one peice so it will help prevent creaking, but it is very expensive, and the bearings will wear out even faster.

I see ceramic speed also offers a bb86/dub option. Are they worth it or will it likely suffer the same high wear-rate as the other 2 options you mentioned?

Btw so you're saying SRAM doesn't even offer a dub BB that fits bb86?

I definitely would not spend the money on ceramic bearings, especially for a BB86/sram combo.

Then, actually, the Sram BB that you originally listed will work for a BB86...the BB86.5 that they listed threw me off.
