Ceramicspeed BB86 Shimano MTB Bottom Bracket sport factory

The BB86 mountain bike standard was designed to integrate bearings into the bottom bracket for weight reduction. This kit works with the standard: it consists of two cups that are pressed into either side of the shell.

There are two versions of this bottom bracket. Both come with CeramicSpeed Bearings installed into cups. The first is our long life, low drag Standard Bearing, with hardened-steel races and our CeramicSpeed super round, super hard balls. The second is our coated bearing, which uses those same CeramicSpeed Balls installed on coated, hardened-steel races for longer life and less bearing drag.

This CeramicSpeed BB86 Bottom Bracket meshes with thru-axle cranks that have 24mm spindles, including both Shimano and FSA.

CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That means an average 75% drag reduction compared to standard bottom brackets. The hardened-steel races feature CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. The CeramicSpeed Bearings last at least three times longer than other bearings.

Coated Bearings drop friction further and increase lifespan to applying a coating to the races. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.

LongLife Grease comes installed, but can be changed for lower drag All Round Grease, which is fine for less extreme conditions.
