Discover WS2 coated Ceramitech, Ceramitech, and ABEC-7 bike bearings here at BBInfinite. Our selection of bicycle bearing replacements are sold in pairs and include options for 6805, 6806, 6706, 4030, and more. Ceramitech bearings are processed with additional heat treatment steps, resulting in a bike bearing that resists ceramic-induced wear and provides a smooth ride. Our ABEC-7 bearings are rated with a tight tolerance and provide better precision.

If you’re unsure of which bearing you need, we have provided information on each page to guide you to the right option. Still unsure? Email us at info@bbinfinite.com or call us at 866.865.3335 (9am-7pm CST) for further assistance.
