The 3 in 1 Core System BB set can accommodate for three different crank spindle specifications. Easily switch between different cranks without the need to change the Bottom Bracket.

Compatible with the universal BB tool with an O.D. 44mm, eliminating the need for various specialized tools.

The ceramic bearings utilize G5-grade ceramic balls and are paired with precisely machined steel race, delivering excellent rotational performance for riders.

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.
