Bottom Brackets

The bottom bracket is one of the most important components of your bike's drive system. It is the bearing that makes pedalling and the transmission of your power via crankset, chainrings, chain and sprocket to the rear wheel via the tyre to the road possible. In principle, the bottom bracket is positioned between the shaft on which your crankset is mounted and the frame; in the case of square bottom brackets, which are still common today, the shaft is part of the bottom bracket. Often underestimated by customers in the workshop - after all, you can't see it - bottom brackets ensure low-friction rotation of the crank arms and absorb the forces that occur when pedalling. Due to the forces that act on the bearing as a result of the pedalling motion, it is considered to be the most heavily loaded bearing on the bicycle. Bottom brackets are wearing parts and should be replaced at regular intervals.
