-JetStream Pro Bearing-

Jetstream Pro Series stands for Rotation Optimized Ceramic Technologies. Because it takes more than just ceramic balls to minimize friction and gain watts. It´s about the composition of race, seal, lubricant and balls. Jetstream Pro Series delivers the right composition for the purpose. The JetStream Pro series offers exceptional efficiency and durability, backed by a reassuring four-year warranty for users.

G3-grade perfectly round ceramic balls create lower rotational resistance, allowing your power better to convert to speed.

NC Race Bearings have a Nano coating on outer & inner races, This dry film can minimize the coefficient of friction to as low as 0.03 dynamic, and 0.07 for static. The Nano Coating overcomes or reduces mechanical lubrication problems improving performance and extending service life >300%

While Supra LV is focused on pure Performance of the Pulley Wheel, TRiPEAK chooses a different  lubricant character for the ceramic bearing Bottom Bracket: The Eterna Low Viscosity (LV) Lubricant has the characteristics to be durable reliable and keep rotation silent.

ZERO Contact Seal, a non-contact bearing seal, provides complete coverage without increasing rotational resistance, striking the optimal balance between efficiency and protection.

-G5 Ceramic Bearing-

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

-P05 Steel  Bearing-

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.
