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%.

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

T47 threaded BB cups for T47 frames and 24.00mm spindle diameter cranks. Cups have internal bearings and are typically used in BB shells with widths wider than 73mm. Machined aluminum cups thread together directly into a T47 BB shell. Bearings are easily serviced or replaced. Includes sleeve to fit between cups for added protection from dirt and grime, and also keeps your internal wires and hoses from rubbing on the crank spindle.
T47 BB cups are similar to standard BSA threaded cups in that the drive side cup is left-hand thread and the non-drive side cup is right-hand thread. Use a quality grease when installing in steel or aluminum BB shells, and an anti-seize compound compatible with titanium BB shells.

BSA is equivalent to English threading. 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 works with 24mm diameter cranks, such as Shimano, FSA, Rotor, and others.
Choose between two bearings for the cups. Standard Bearings have low drag thanks to hardened-steel races and our Ceramic balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag.
English threading is easy to work with, and 24mm spindles easily fit through the shell, allowing for large bearings to be employed in the outside cups.
Put more of your energy into forward motion by reducing frictional drag wherever you can. 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. CeramicSpeed balls are 100% smoother and 15% harder than ceramic competition. The bearings last at least 3x longer than other bearings.

The EVO386 standard is designed for oversized spindles. CeramicSpeed's kit for Shimano allows you to install Shimano or FSA cranks with 24mm spindles.
The cups come with CeramicSpeed Bearings installed. Both CeramicSpeed Standard and Coated Bearings are available. Both utilize super smooth CeramicSpeed Balls and hardened-steel races. The latter has an additional metallic coating on the races to further smooth and harden the steel, further increasing life and lowering drag.
The design of overlapping cups extending through the shell for EVO386 reduce the likelihood of creaking and increase the reliability of the system.
The CeramicSpeed Standard Bearings feature an average drag reduction of 75% compared to stock bottom brackets. That translates into frictional drag of 0.3-0.4 watts per set, which is the result of great design, hardened-steel races, and ceramic balls that are 100% smoother and 15% harder than the ceramic competition.
The CeramicSpeed Coated Bearings are a step up as they reduce drag by 50% compared to our Standard Bearings and an improvement in bearing life by 60%.
All Round Grease comes standard in the bearings, but can be replaced 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
