Technical Data of CeramicSpeed BB86 Bottom Bracket for Shimano

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

CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That represents an average 75% drag reduction compared to standard bottom brackets. The hardened-steel races feature the 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. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.

Changing the grease can tune performance. All Round Grease comes installed, but can be changed for lower drag Race Day Grease, or higher durability Long Life Grease, which adds a bit of drag but stays in when riding through messy conditions.


Our coated products are covered by a lifetime warranty. The unique coating formula is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides even lower friction than our standard bearings. Even if the bearing is contaminated with degreaser, water, or mud, the risk of bearing failure due to corrosion is negligible if you choose the coated version.
