Ceramic Bearings Cycling Review

Bottom brackets bearings and pulleys are arguably one of the most essential part of the bicycle that is the most overlooked.

Ceramic bearings cycling review. The problem here is that wheels take hard impacts from potholes. Hand built in denmark. The ceramicspeed bottom brackets guarantee you the lowest friction optimised power transfer and longest product lifetime helping you to save watts and ride faster. In most bearings the grease is the main source of friction.

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. When a bike with ceramic bearings goes over a bump the ball bearing which is harder than the steel race that contains it strikes the inner surface of the race.

On top of all that ceramic balls do not rust or oxidize.

It s clear that alan and paul agree that the factors that make a ceramic bearing well suited to industrial and medical equipment applications and high altitude operating drone motors paul does a lot of work designing drones where the rpm is high the load is low and the operating conditions are clean are factors that mean they re not suited to cycling. Lets start with the bottom bracket. Ceramic which is significantly harder does not have this ability.

This impact leaves a very small dent or pit in the steel race. Ceramic bearings are beneficial in environments not requiring grease lubrication says lew.

The silicon nitride used to make ceramic bearings combines a set of material properties that makes it perfect for bicycle bearings. Full ceramic wheel bearings would be an amazing way to reduce friction in hubs.
