Bearing Info

Enduro ZERØ Ceramic Bearings

Enduro ZERØ Ceramic 6806 Bearings

The 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

  • ABEC-5 rated Ceramic Hybrid bearing with Grade 3 balls
  • Cryogenically treated races will outlast any other bearing on the market
  • Dual lip, groove type seals keep dirt out and 90% fill rate grease in
  • Rheolube special synthetic grease is long lasting and protects against contamination
  • USA made balls are micro-coated with long lasting protection from friction

We back them up with a 1 year warranty.*

Compatibility

Directly replaces all OEM BB386EVO bottom brackets.

Compatible with the following Bottom Bracket Standards:

  • BB386EVO, BB392EVO

Wheels Mfg 386EVO-BB + 386EVO-SRAM adapters will not work with Quarq SRAM/GXP cranksets (Elsa, Riken, SRAM Red 22, SRAM S975, SRAM S2275, CinQo Saturn, Saturn2). The outer diameter of the bottom bracket cup faces are slightly larger than the recessed section of the Quarq power meter and the two will rub together. If your Quarq spider has an ID less than 49.5mm, it will not fit over our 386EVO-BB cup.

  • Includes older Saturn power meters that use CR2450 batteries
  • Includes newer 3-bolt and 8-bolt Mercury power meters

The new Quarq DZero powermeter spiders will work with Wheels Mfg 386EVO-BB + 386EVO-SRAM adapters
