SRAM’s step-down 24/22mm diameter crank spindle is found on SRAM and Quarq cranks. This kit makes it easy to install those cranks into your BB30 frame.

Bottom brackets deal with lots of force. Our ceramic bearings and hardened-steel races are stiff and efficient. CS Standard Bearings produce only 0.3-0.4 watts per set. The bearings are in the range of a 75% reduction of drag compared to stock offerings. They also last at least three times longer than other bearings.

Coated Bearings put even more of your power into driving forward. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.

The grease packed with the bearings can tune performance. All Round Grease comes installed, but can be changed for lower drag Race Day Grease, or higher durability Long Life Grease, which adds a bit of drag but stays in when riding through messy conditions.
