Road Bike Wheels With Ceramic Bearings

The hubs with usb ceramic bearings ultra smooth bearings further enhance the triathlon and road bike wheels smoothness and reduce weight and the need for maintenance.

Road bike wheels with ceramic bearings. After all since there are no chance for parts to oxidize there is also no need for grease. Because ceramic bearings are rounder with a smoother surface and more uniform size friction is reduced and that can contribute to a less energy required to turn the cranks or spin the wheels. In most bearings the grease is the main source of friction. The problem here is that wheels take hard impacts from potholes.

Been to the bike shop and spun the wheels to see which feels the fastest. We ve all done it. Full ceramic wheel bearings would be an amazing way to reduce friction in hubs. Wheels can still seem to roll and spin perfectly fine even when there s no grease in the bearings or worse the bearings are dry and binding so bad that you can barely turn the axle by hand when the wheel is off the bike.

Xd15 super nitrogen stainless and silicone nitride ceramic are all available and then some. Comparative tests have shown that usb bearings are 50 smoother than standard bearings. While regular bearings are made from stainless steel ceramic bearings are made from ceramic silicon nitride si2n4. Rolling resistance is the key trump card promoted by ceramic bearing fans.

Inevitably discussion ensues as to which bearings the wheels have and whether they are ceramic or not.
