The SRAM DUB bottom bracket series has a simple job—connect your crankarms and protect the smooth, long-lasting application of power to your drivetrain. To allow that singular focus, we've engineered the DUB spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket standard. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride. - One oversized spindle to work across every bottom bracket standard - Greater bearing durability

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 PF30 for SRAM DUB Road comes in two versions. One version uses our low-drag, long-life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls.

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

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 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 All Round Grease - Sticker sheet
