Bottom brackets should simply work. “Install and forget” is our motto and with this in mind we developed our bsa bottom bracket. Since what counts most for us is the inner values, we use double-sealed angular contact ball bearings in our BSA bottom bracket. These stainless steel industrial ball bearings can absorb the forces that occur when pedaling much better than simple deep groove ball bearings. In addition, the ball bearings are protected against dirt and water with a special protective cap. It also prevents contact between the crank axle and ball bearings. In this way, we reliably prevent the creation of popping and creaking noises and ensure your worry-free experience on the roads, gravel roads and trails of the world.
