Technical Data

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

CeramicSpeed standard Bearings typicallyhave 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 racesfeature the CeramicSpeed Balls that are 100% smoother and 15% harder than theceramic competition. The CeramicSpeed Bearings last at least three times longerthan other bearings.

Coated Bearings drop friction further andincrease lifespan. The coated races see a 50% drag reduction and an improvementin bearing life of 60%.

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