The bearing races and balls are made from ZrO2 (Zirconia) making the bearing a lot lighter, faster and more energy efficient with reduced friction. The cage and seals are made in PTFE to maintain the low weight & friction. Our full ceramic bearings come without grease because they are classed as self-lubricating.

We recommend our full ceramic bearings for track/velodrome riding, However if you consider yourself competitive and have a bike/wheelset set aside for racing then they could work very well for you.

Full ceramic bearings are a lot harder & tougher than steel bearings but at the same time they are more brittle & therefore susceptible to shock loads such as hitting pot holes (which we have a lot of in the UK) on the roads which could lead to cracks in the bearing races and eventually bearing failure.
