Ceramic Bearings Do They Work?

When it comes to cycling, most people are looking for the speed factor and when it comes to speed its always relate to weight, that that will relate to “MONEY” with a lighter bike you will definitely use less energy, but there are many theory against this (something about moving mass etc etc)

This post is not about weight anyway, its more of this material composition called “Ceramic” , people are paying top dollar when it comes to ceramic, being watches, phones, jewellery etc..etc.. and this virus has also infected the biking industry, but dont be surprise that ceramic has been around for ages So why does one ceramic makes it so much faster?

Integrity – Ceramic bearings are 10 times rounder than steel bearings and 20% more rigid. No part of the bicycle is subjected to more intense physical conditions than bearings, increased stuctural integrity in the bearings leads to a more efficient bike.

Durability – In various tests, ceramic bearings have been found to be 5-20 times more durable than steel bearings. So if your steel bearings typically last 3-4 years, ceramic bearings should last a minimum of 15 years.

Weight – Ceramic bearings weigh 40% less than steel bearings. Weight savings are most beneficial on rotating parts, nothing on your bike rotates faster than the bearings.

What do these numbers mean for a rider? Well, FSA did some testing and found that a bike equipped with ceramic bearings was 4% more efficient than the same bike equipped with steel bearings. So for every 100km ridden on the steel bearing equipped bike, the ceramic equipped competition rode 104km, while expending the same amount of energy. If we assume the peloton averaged 40km/hr, that’s a win by…..SIX MINUTES!

I was suppose to embark on my project which is long overdue, it was the “Parts by Parts” project which involves building a bike parts by parts, and by building everything from scratch this ceramic bearings has come to my attention, Do watch the video and let me know what you think?  Do you believe in them or not?

  1. I’ve thought about putting ceramic bearings in my Trek Madone road bike but haven’t done it yet. However, the next time I replace the bearings I imagine I will — not for the weight savings but for the durability.

    • Not sure about durability, but I have ordered mine from UCB, have seen alot of ceramic bearings like F1, Ceramic Speed, Hawk (not sure if its ceramic) even one calling it not ceramic but Tiramic
