Technical Data Enjoying the benefit of a massive, strong, and light 30mm crank spindle in your BB86 frame is possible with this kit

Press in the cups, set up the wave washer, add spacers if necessary, and torque down

CeramicSpeed’s bottom bracket is also stiff and light, but it’s biggest benefits are from drag reduction

Standard Bearings with stock grease typically have frictional drag of 0

3-0

4 watts per set

That’s in the range of a 75% drag reduction compared to conventional bottom brackets

The bearings last at least three times longer than other bearings

Performance can be tuned by grease choice

All Round comes with, but you can change it to TT and Track Grease for less drag or to LongLife for greater durability
