While they’re not often subjected to the thrashing their mountain bike counterparts are subjected to, Road Bottom Brackets still have a pretty tough life. They must have seals that are drag free as possible, so they can spin smoothly with minimal friction, saving precious watts and energy over the distance of a ride or race. But they must also have good enough seals that grime, dirt and spray from the road doesn’t work its way into the bearings and lead to premature failure. Nobody wants to change a bottom bracket every few rides.
After years of constant development, you can now have your cake and eat it. Road Bottom Brackets now offer exceptionally smooth running teamed with fantastic durability and the beauty of the technological trickle-down effect means any road bike, old or new, can enjoy the benefits of a smoother, more reliable bottom bracket. Whatever standard your road bike uses, you’ll be able to find one to fit here.
