acros t47 bottom bracket

When you think about bottom brackets, sophisticated technology typically isn't the first thing to come to mind, especially when they simply do their job. Since our bottom brackets remain largely unnoticed as you ride, we'll tell you what sets them apart: double-sealed deep groove ball bearings made of stainless-steel, which have been specially optimized to deal with pedaling forces. The additional outside seal keeps out the elements, and shields the contact points between the crank spindle and the ball bearings. This effectively prevents creaking noises. For added protection, all acros bottom brackets come with a connecting sleeve between the bearing cups, which keeps the ball bearings free of dirt and moisture that may have gotten into the frame.

Unfortunately, all ball bearings eventually wear out, and there's nothing we can do about that (yet) either... For this reason, we've designed our bottom brackets to make the ball bearings as easy as possible to replace. You can find the right replacement bearing set and bottom bracket bearing tool in our shop.
