380mm long, single-ended straddle for mountain cantilever brakes

The BB30 standard opened up design possibilities for frames. Adapting it for Shimano cranks takes a special machined aluminum threaded bottom bracket that threads into itself. Ours are finished with CeramicSpeed Bearings. You have two choices in terms of bearings. The first choice is our low drag, long life standard bearing with hardened-steel races and our super-round CeramicSpeed Balls. The second choice is our coated bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag. This bottom bracket works with cranks that have 24mm spindles. Bottom brackets have several variables, but within that, CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That's in the range of a 75% drag reduction compared to standard bottom brackets. That's thanks to 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 see another big bump in performance. The coated races see a 50% drag reduction and an improvement in bearing life of 60%. Performance can be tuned by changing the grease. All Round Grease comes installed, but can be changed for lower drag TT and Track Grease, or higher durability LongLife Grease, which adds a bit of drag but stays in the bearing when riding through messy conditions. In The Box: - 1 bottom bracket with bearings installed - 2 dust covers installed - 10ml syringe of CeramicSpeed All Round Grease - Sticker sheet

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 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%. In The Box - 2 bottom bracket cups with bearings installed - 2 dust covers with integrated spacers installed - Spacer tube - 10ml syringe of LongLife Grease - Sticker sheet
