Cartridge bearings are used throughout bikes, regardless of whether they're a road bike, mountain bike or gravel bike. Common uses for these bearings are in headsets, hubs, bottom brackets and suspension pivots for full suspension mountain bikes. There can be quite a big difference between a good bearing and a bad one, so how do you know what kind you're getting? At Westbrook Cycles, we always recommend using Enduro Bearings as we not only sell a lot of them and never hear any complaints from customers, but our staff all use them too. All Enduro bearings are manufactured to at least an ABEC 3 grade, which exceeds the industry standard, and they also offer bearings of ABEC 5 standard for anyone really looking for high performance. These ABEC grades not only certify that the bearings are manufactured to a high standard, offering little by way of friction, but they also use high quality greases and seals to guarantee unrivalled longevity. Above you can see our complete range of Enduro bearings, and if you're not sure what you're looking for, please get in touch and our staff will be happy to help.
