Proven time and again in World Cup race conditions, the ZERØ Ceramic bearings are the ultimate race day weapon. Oversized Grade 3 balls roll on races which are ground to a mirror finish after receiving Magnetite and then Cryogenic treatments for hardness and longevity. More durable and with even lower rolling resistance than any 2RS bearings, they come closer to that magic “zero” rolling resistance number. Enduro Bearings uses Silicone seals which are more slippery than rubber seals used by other ceramic bearing suppliers. We get more email and blog feedback on the ZERØ's than any other bearing, describing the noticed difference in downhill rolling speed. And they win the independent wattage output tests when stacked against the competition. If you want to buy raw speed, ZERØ bearings are it.

- ABEC 5 precision cartridge bearing
- CERBEC USA Grade 3 Si3n4 Silicon Nitride balls
- 52100 high carbon Chromium alloy races
- Races receive 3 cryogenic treatments and a rust proof Magnetite finish
- "VV" type 2-lip non-contact Silicone labyrinth seals

Enduro VV Type Seals
Developed with the idea of rolling as fast as possible, this dual lip configuration does not make contact with the bottom of the machined groove. Since these bearings also have a high rate of grease fill, the grease migrates to the bottom of the groove where a hydromatic type seal is established between the 2 lips and the grease in the groove. This grease barrier keeps the dirt and contaminates from coming inside the bearing, while still rolling smoothly and with the least resistance of all our bearings.
