FAQ

Our motto is, "Fit and forget." Nothing is more annoying than bike parts that leave you in the lurch and require lots of maintenance or attention. Your time is valuable and if at all possible, should be spent riding your bike. That's why we use several seals which, together with our special grease, contribute to a durable bottom bracket you can enjoy for a long time.
If you use your bike as intended, at some point your bottom bracket will wear out. You can only really prevent that if you ride your bike solely for fair-weather jaunts along the cycle path to the local ice cream parlour. Bearings are and will remain consumable parts. But the good news is that if you don't blast the bottom bracket with a pressure washer and are sparing in your application of bike washes like Muc-Off close to the bearings, your bottom bracket should deliver long-lasting durability.
Bikes and their components are often quite complex, alone due to the many standards available. If you have any more questions, please feel free to get in touch.
