We are a premium dealer and test center for [Enduro Bearings] . Enduro offers high-performance, carefully designed and manufactured bottom brackets, pulleys, fork seals and tools. No expense is spared in creating the ultimate bearing, components and tools.Enduro offers steel bearings and high-grade (5 or 3) ceramic bearings in their bottom brackets, pulleys and fork seals.

Ceramic bearings usually refer to ceramic ball bearings. Canonically, ball bearings are made from hardened chrome steel. Ceramic balls can be made of various materials such as zirconia, alumina or silicon nitride. The most common material used is silicon nitride as it is more durable and less brittle than other ceramic materials. Ceramic cartridge bearings are a bit more involved. Pure ceramic cartridge bearings use ceramic balls on ceramic bearing surface. The ceramic bearing surface is extremely difficult to manufacture and thus very expensive. Most ceramic cartridge bearings are actually hybrid bearings. A hybrid bearing is a bearing with ceramic balls on a steel bearing surface. Hybrid bearings offer incredible performance (if done correctly) over conventional steel on steel bearings.

First, ceramic balls are almost twice as hard as bearing steel. The harder the material, the less the bearing will deform. Additionally, the harder bearing material will be more durable which is why ceramic bearings are known for their durability. Ceramic bearings are also less dense and in theory will accelerate more quickly and dissipate heat more readily. These last two properties are not as important to cycling applications as ceramic bearings are often rated to over 10,000 rpm. Last but not least, ceramic bearings can generally be made more round than steel ones. The ceramic balls we use are Class 5 or better. The Class of a ball bearing refers to its sphericity in millionths of an inch. Thus, our bearings are round to 5 millionths of an inch and better in many cases. In comparison, the best bearings that come stock in Campagnolo Record or Shimano Dura-Ace is Class 25. That means our ceramic bearings are at least 5 times more round which results in less rolling resistance.

When we install bearings in our wheels and bottom brackets, we use high end bearing pullers and presses that correctly align the bearings. This will guarantee that bearings will spin as smooth as possible. We check all of wheels and bottom brackets after installing ceramic bearing installation for correct alignment.
