The P05 precision steel ball bearings, for reassuringly high smoothness and durability. 0.005 mm for eccentricity (out of roundness) of the track in the inner race. That´s precise.

The Twist-Fit design accomodates press-fit BB specificied frames, making the BB installation and removal easier. Dual-sided locking enhances the precision of the spindle and avoids creaking noises by achieving a perfect alignment between the bottom bracket and the crankset spindle.

The patented plastic-steel bushing design is a big relief for Press-Fit frame BB users. It prevents wear on the frame's bottom bracket shell when the BB is pressed in. Snug Fit effectively eliminates noise and corrects bottom bracket tolerances.
