Do Ceramic Bearings Make A Difference

If only high quality ceramic bearings are used marginal gains will.

Do ceramic bearings make a difference.

If a cyclist has ridden a bike fitted with ceramic bearings and then returns to steel bearings it is likely that slightly more vibration will become noticeable. Rolling resistance is the key trump card promoted by ceramic bearing fans. However while the ceramic balls will still abrade the steel rings hybrids will cope with marginal lubrication better than steel. 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.

For example while full ceramic bearings do not require lubrication hybrid bearings do. Despite the small difference in design hybrid bearings requirements differ quite extensively from full ceramic bearings. The first thing that strikes the eye when looking at bicycle bearings is the difference in price between steel bearings and hybrid ceramic bearings. While regular bearings are made from stainless steel ceramic bearings are made from ceramic silicon nitride si2n4.

The bearing clearance is a measurement given to the small gap between the inner race outer race and balls. It is required to prevent bearing seizure when it warms up and expands. Fitting ceramic bearings will make the bike feel like it is rolling smoother. The only real big noticeable difference between the two is the bearing clearance.

Cost of purchase for ceramic and steel bearings. This is mostly due to the additional time spent to perfect a quality ceramic ball.
