A quick summary of some of the more important tech data
We have a very detailed selection of articles on ceramic bearings. We recommend you read through all of them to learn more about our bearings. But for those who don't want to read that much, here is a quick list of the highlights, in no particular order.
- Your new bearings need to break-in before the performance really starts to show. Give them a few hundred miles at least for the grease to spread, the seals to break-in and the races to polish.
- No, we do not offer a full ceramic bearings (ceramic balls and ceramic races), only hybrid ceramic bearings (ceramic balls with our 52100 high carbon chrome race) except for in our pulleys. Full ceramic bearings are a bad idea for cycling since a ceramic race isn't good with taking impact and should be avoided. The only place where a full ceramic pulley will work correctly is in the rear pulleys.
- Yes you have to do maintenance on our ceramic bearings. They are a high performance part and should be taken care of. Failure to keep them greased will lead to failure.
- Yes, ceramic bearings are faster than steel bearings. The materials in our bearings are more precise which means they turn easier when you ride.
- The infamous "Spin Test" is not the greatest gauge of performance since it shows seal and grease resistance only (unloaded) but we have posted a video of a brand new (no break in time) VCRC Ceramic Bottom Bracket with our bearings installed to give you an idea of the lack of resistance. Please note this is only half the benefit of upgrading to ceramic. The other half happens when you ride!
- I thought your bearings were sealed, why do they need maintenance? They need maintenance because there is a huge misunderstanding about what a "sealed bearing" means. Most people incorrectly think sealed means "sealed off from contamination and needed maintenance" when really it just means the bearing uses rubber seals instead of metal shields.
