Full Ceramic Bike Bearings Have Arrived
The Boca Bearing Company continues to be innovative in the Bicycle Bearing market by introducing cutting edge, Full Ceramic bearings with protective seals. Full Ceramic bearings give competitive cyclists the absolute minimum amount of rolling resistance of any bearing on the market. Full Ceramics have Zirconia (ZrO2) races and balls as well as protective Teflon seals and retainers. These bearings require no lubrication at all, which substantially lowers rolling resistance even further.
Zirconia (ZrO2) Full Ceramic bearings are recommended for all bicycle components like hubs, bottom brackets, pivots and headsets. They are also suitable for all bicycle applications such as Mountain Bikes, CycloCross, Velodrome and Road bikes. Full Ceramics are also decidedly lighter than both standard and ceramic hybrid bearings being two-thirds the weight of steel.
Boca Bearings makes it easy for consumers and repair shops to find the exact bearings for their bikes. A full cross reference guide for all of the popular hubs, bottom brackets, headsets and pivot points is available from the website or upon request. International and Dealer discounts are available. Media samples are available for review and high resolution images are provided by download below.
