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.

Unlike traditional press-fit bearing pulleys, Tripeak's injection-molded pulley fully encases its bearing, ensuring a perfect zero-tolerance fit between pulley body and bearing. The composite material of the pulley body enhances its wear resistance, resulting in quieter and more efficient operation. Compared to traditional aluminum pulleys, it significantly extends the lifespan of both pulley and chain.

The Narrow-wide Tooth Design allows the pulley to better engage with the chain, significantly improving operational stability.
