CØ 6806 VV Zero Ceramic Enduro Bike Bearing 30.00x42.00x7.00

Typical applications: BB30 Bottom Bracket

  • Silicon Nitride (Si3n4) Grade 3 balls
  • Silicone VV type seal
  • Magnetite Rust Proof Finish

ZERØ ceramic bearings have ceramic balls and steel races.  The balls are Grade 3, Silicon Nitride (Si3n4).  These are the roundest balls you can buy without a military license.  The races are treated with a black oxide coating, which helps prevent rusting in the bearing. The races are then reground to a mirror finish after this treatment. Finally, they are cryogenically treated for strength before assembly. We also use Silicone VV seals, which is the lightest drag seal available on the market.

Si3N4 balls with 52100 High carbon Chromium Alloy Races with Cryogenic Treatment:
 Cryogenic treatment takes the races down to minus three hundred degree Fahrenheit to normalize the crystalline structure of the material so the races will resist the hardness of the ceramic balls and get the maximum wear potential.

Took out the old bearings and replaced them with these. Went in a treat, No issue putting the bike back together and they have been perfect ever since. 250 miles covered so far and as smooth as a "babies bum".
Spot on I will be back if and when I need some more.

The strong, silent type

Replaced my second set of BB steel bearings with these. Early days yet but my bike is now clickless. Can't say I notice any difference in pedaling but on the work-stand they are silky smooth.
