Ceramic Bearings For Bicycle Hubs

However the reality of why some bearing designs are faster than others doesn t always align with what is presented.

Ceramic bearings for bicycle hubs.

The influx of ceramic bearing development into the bike industry sparked needed focus on reducing rolling friction in bearings. A tiny percentage reduction in friction here can equate to a worthwhile power saving but when you re only turning at 300 rpm as you do on a bicycle a small percentage increase in efficiency will make a negligible change to your power output. Two types of ceramic materials there are two materials that are common. Ceramic bicycle wheel bearings kogel bearings offers ceramic wheel bearings for any wheelset.

They ceramic bearings do run with less friction which offers a significant advantage in industrial applications running at 20 000 rpm.

Crafting the fastest bearing products for cycling and industry since 2004. Leading industry wheel dynamics expert and ceo of edco wheels paul lew backs this up and reckons it makes ceramic bearings a poor choice for hubs and headsets also adding that they offer no weight savings and are only beneficial in environments where high rpm revolutions per minute are required. Enduro zero ceramic grade 3 6803 cartridge bicycle bearing 17x26x5mm. Fitting ceramic bearings on your bike may be a bit like fitting a formula one gearbox in your ford fiesta and expecting it to perform as well after 100 000 miles.
