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
