JetstreamPRO NC Ceramic Bearing

Engineered to reduce rotational resistance and minimize energy loss.

With smoother bearing performance, more of your power is efficiently transferred into speed.

Less resistance. More efficient power transfer.

NC Race Bearings have a Nano coating on outter & 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%

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

Supra LV is a special Low Viscosity  lubricant for the ceramic Pulley Bearings. It offers high flow characteristics for a fast and smooth operating environment. Easy to lubricate in maintenance without removing the seal of the bearing.

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.
