Shimano cranks fit into BB86 frames when you have this CeramicSpeed Bottom Bracket installed. The kit consists of two cups that are pressed into either side of the central opening. The cups come with CeramicSpeed Bearings installed. There are two versions. The first is our low drag, long life Standard Bearing with hardened-steel races and our super-round CeramicSpeed Balls. The second version 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 works 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 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 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.

BSA is another way of stating English threading. The initialization comes from Birmingham Small Arms, which made bicycles. English threading on road bikes mean a 68mm-wide, 34mm-inside-diameter shell with reverse threading on the drive side. It's the most common threaded standard employed today. This kit allows you to fit 30mm cranks, like those from Rotor, to fit in the tight space of this 34mm spindle. Choose between two bearings types for the cups. Standard Bearings have low drag thanks to hardened-steel races and our CeramicSpeed Balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag. Note that the threaded extensions of this BB's cups that thread into the frame are thin, as they need to fit a 30mm spindle inside the cups. 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 bearings last at least 3x longer than other bearings. In The Box: - 2 threaded cups with bearings installed - 2 1mm spacers - 2 0.5mm spacers - 2 dust covers - O-ring - 10ml syringe All Round Grease - Sticker sheet - Spacertube

Italian-threaded bottom bracket shells are typically found on Italian-brand road bikes. The shell measures 70mm wide and has a 35mm inner diameter. This kit has all the pieces necessary to install 24mm diameter cranks, such as those from Shimano, FSA, and others into an ITA shell. CeramicSpeed bearings are pressed into threaded cups, then those cups are threaded into the frame. You choose whether you want yours equipped with Standard or Coated Bearings. Super-round, super-smooth CeramicSpeed balls rotate in hardened-steel races in both. The Coated version has a metallic coating laid onto the races, making them even harder and smoother, resulting in longer life and lower drag. ITA BBs, thanks to the popularity of Italian road bike design, still have a following. The drive-side cup needs to be properly secured, but once that's done, the system is excellent. 24mm cranks work better when mated to our bearings. To make your bike as efficient as possible, you must reduce mechanical drag. Bottom brackets have a measurable effect on speed. CeramicSpeed balls are 100% smoother and 15% harder than the ceramic competition. They run on smoother races, too. That means our Standard Bearing BBs have 75% less drag compared to typical bottom brackets. And, the bearings last at least 3x longer than other bearings. These bearings come packed with All Round Grease. If you want less drag and are riding in cleaner environs, install lowest drag TT and Track Grease. If you're riding in wet conditions, more durable LongLife Grease can be put in. In The Box: - 2 threaded cups with bearings - 2 dust covers with built-in spacers - Spacer tube - 10ml syringe of All Round grease - Sticker sheet
