CØ 6902-VV Zero Ceramic Enduro Bike Bearing 15.00x28.00x7.00
Typical applications: Hub Bearings
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.
When the bearings in my FFWD wheels gave up, I thought I would splash out the extra and get ceramic bearing to replace them.I don't know whether it's my imagination but they absolutely seem smoother and run better than ever. The service from Wych was also faultless so would not hesitate to recommend both the bearings and the supplier !
Was this helpful to you? Yes / No
I am a cyclist (time triallist) and I ordered my Enduro ceramic bearings from Wych Bearings over the phone. I actually knew which bearings I wanted, but a chat with the member of staff on the phone confirmed that I was ordering the best bearings for the job (for my rear disc wheel). Delivery was quick. The whole thing was fuss free. Recommended.
Hi, the service was from use of the website to delivery very slick and easy,will gladly use you again in the future.
