Please could i have some views on ceramic wheel bearings and the preferred manufacturer of these for bontrager wheels thanks.
Ceramic wheel bearing waste.

Been to the bike shop and spun the wheels to see which feels the fastest.
The problem here is that wheels take hard impacts from potholes.
Full ceramic wheel bearings would be an amazing way to reduce friction in hubs.
Each of the kits includes low resistance hybrid ceramic ceramic balls and steel cages bearings and offer a measurable wattage savings between 1 5 and 9 watts per bearing set depending on the condition of your existing bearings.
In most bearings the grease is the main source of friction.
We ve all done it.
Ceramic bearings in your jockey wheels does not save a couple of watts.
In this test they compared the durability of ceramicspeed bearings to other ceramic wheel bearings.
Inevitably discussion ensues as to which bearings the wheels have and whether they are ceramic or not.
Performance bearing offers replacement ceramic bearings to replace your antique steel bearings in your wheel and axle bearings transmission and gearbox bearings camshaft bearings and special applications for high speed industrial machine tools.
Wheel bearing test bearings lubed with oil and tested on a drum which applies a continuous regular impact via an artificial bump.
Honestly they are a waste of time.

It doesn t even save one watt.
For bottom bracket applications the maximum sustained rpm may be 130 explains lew.
They make no noticeable.
After all since there are no chance for parts to oxidize there is also no need for grease.
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.

The difference between dura ace stock steel bearings and top of the line ceramic jockey wheel bearings is on the order of 150 milliwatts.
Waste of money spend 400 on track time instead you ll get more out of it dougmeyer needs a job moderated.
They save a couple of watts which can add up if you have full ceramic bearings everywhere.
