TITANIUM NITRIDE CERAMIC BEARINGS = INCREASED SPEED
 
BEARING FEATURES:
Performance Breakthrough - Speed increases approaching 4%, i.e., over 1 km a rider can gain 20-40m.
TiN Ceramic Bearing Technology,  features proprietary Titanium Nitride coated stainless steel races and cones.
TiN nano-technology surface treatments fill stainless steel pores making the bearing races smoother, harder, and more durable than standard stainless races.
This product is lighter stiffer smoother and will last longer than other ceramic and steel bearings.
High quality Si3N4 ceramic ball bearing
Ti Ceramic bearings are 60% lighter than steel bearings
Ti Ceramic Bearings produce up to 60% less friction
Ti Ceramic Bearings are 15-20% stiffer than steel ones
Ti Ceramic Bearings are resistant to corrosion
Ti Ceramic Bearings have a lifetime 10 times longer than steel bearings
