-DURA Tech  Bearing-

The outer race of the the Jetstream Pro Dura Tech HS is made of Teflon composite material, eliminating the corrosion of metal materials and extending the lifespan. Utilizing Teflon Compound Material  and Ceramic Balls makes the Jetstream Pro DT HS not only 50% lighter than a comparable Steel Headset, it enhances the durability significantly: The CNC machined Teflon race provides an excellent lubeless rolling surface. No need for additional lubrication, no more worries about the complex process of disassembling and assembling the headset. 
 

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

DURA Tech Bearings have a Nano coating on 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%

-CERASYNC Hybrid-

CERASYNC utilizes a synchronized hybrid configuration of ceramic and stainless steel balls, combining the low friction and high-speed efficiency of ceramic with the corrosion resistance and structural stability of stainless steel. This balanced architecture ensures smooth rotation, durability, and consistent performance in demanding and wet riding conditions. 

-Stainless Steel Race-

Built with 440C stainless steel inner and outer races, this bearing delivers outstanding corrosion resistance and all-weather durability. It maintains structural integrity and smooth rotation under humidity, rain, and sweat exposure, reducing corrosion-related wear and extending bearing lifespan for consistent, long-term performance. 
 

-Oxide Coating Bearing-

The bearings feature a black oxide coating on the inner and outer races, enhancing the weather resistance of the headset bearings and extending their lifespan.

-P05 Steel Bearing-

The TRiPEAK S-Series features Po5 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.
