Bearings for the Ultra-Torque cranks are installed on the spindle, resting against the arms rather than pressed into the bottom bracket. A removal/installation tool is necessary; we sell one here, but any appropriate tool will work. Spacers are included in case the bottom bracket shell is too narrow.
We start with our CeramicSpeed Balls in hardened steel races. They create a 75% reduction in drag compared to conventional bottom brackets. It helps that the balls are 400% smoother, 128% harder, 58% lighter than steel. CeramicSpeed Standard Bearings have frictional drag 0.3-0.4w per set with standard grease. They also last at least 3x longer.
Coated Bearings amplify your effort. The coated races find a 50% drag reduction and an improvement in bearing life of 60% vs. Standard.
To tailor your ride to your needs, change grease. All Round Grease is installed; can be swapped for lower drag TT and Track Grease or higher durability LongLife Grease, better for messy conditions.
We recommend that you follow our instructions on how to maintain your CeramicSpeed Bottom Brackets to achieve the lowest friction and the best longevity
