Abec5 Ceramics
Ceramic bearings utilize G5 grade ceramic balls and are combined with a precision machined steel race, providing excellent rotational performance for cyclists.
P05 precision steel ball bearings for reassuringly high smoothness and durability. 0.005 mm for raceway runout (out of roundness) on the inner race. That's precision.
