Testing on FSA Ceramic Bearings (bottom bracket & wheel) has shown speed increases approaching 4% - meaning a rider can gain 20-40m over 1 km! A Record Bottom Bracket and 100 rpm and 400W consumes 0.6W, the same BB with ceramic bearings consumes 0.02W!

FSA bearings combine ceramic balls with super low friction seals and a special lubricant.

Unlike aerodynamics, everyone benefits from reduced bearing friction. Reduced friction so proportionally more important the slower you ride.

Ceramic bearings last 5-10 times longer that steel bearings, so they're a great long term investment.
