NC Race
Bearings
ROC Technology bearings carry a nano coating on the inner and outer races. This dry film cuts the coefficient of friction to as low as 0.03 dynamic.
ZERO Contact Seal
Bearings
A non-contact bearing seal that covers completely without adding rotational resistance — the optimal balance between efficiency and protection.
Dura Tech
Bearings
The outer race of the JetStream Pro Dura Tech headset is Teflon composite, eliminating metal corrosion and extending service life.
JetStream Pro
Bearings
JetStream Pro stands for Rotation Optimized Ceramic technologies — it takes more than ceramic balls to cut friction and gain watts.
