CeramicSpeed ITA Bottom Bracket for SRAM DUB Road
$359.00
The new SRAM DUB crank standard, built on a 28.99mm spindle, allows for a more contamination-resistant BB design, while retaining the ultra-efficient & long-lasting qualities CeramicSpeed Bottom Brackets are known for. With an integrated dust cover for all models, the snug & secure fit not only fully protects the face of the bearing, but also delivers exceptional performance without any sacrifices. CeramicSpeed hand-built bearings carry the load from crank to frame with unparalleled durability & efficiency. The SRAM DUB crank spindle requires the bearing contact points to be in a set and designated width, and all CeramicSpeed bottom Bracket options perfectly match the bearing placement on the crank spindle with the required frame interface for nearly any model of bike. Without the use of unnecessary adapters or spacers, a quiet & stable platform is ensured throughout the life of the product. The ITA for SRAM DUB Road comes in two bearing options. The first option is our low drag, long life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The second option is our Coated Bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag. Compatible with: - Frame: Italian BB - Opening diameter: Threaded - Shell width: 70mm In the box: - 2 cups with CeramicSpeed Bearings installed - 2 dust covers - 4 x 1mm spacers - 10ml syringe of CeramicSpeed All Round Grease - Sticker sheet - Spacer tube

CeramicSpeed BSA for Shimano Road
$479.00
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. In The Box: - 2 threaded cups with bearings - 2 dust covers with built-in spacers - Spacer tube - 10mm syringe of All Round Grease - Sticker sheet
CeramicSpeed BSA Bottom Bracket for Shimano Road

BSA is another way of stating English threading. The initialization comes from Birmingham Small Arms, which made bicycles.

This kit works with 24mm diameter cranks, found on cranks from 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. 24mm spindles easily fit through the shell and allow for large bearings to be employed in the outside cups.

CeramicSpeed BB30 Bottom Bracket for Shimano Road
$379.00
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
