Krankboks / Krankleje
As bottom bracket refers to the bearings of the bicycle to which the crank set is attached. The crank arms are then mounted onto the bottom bracket shaft.
Bottom brackets perform their role invisibly, yet they are the most heavily loaded bearing of the bicycle. Therefore, you should pay particular attention to high quality when buying these parts.
The bottom bracket that fits your bike depends on the bottom bracket housing of the frame and the crank which is used. With each bearing in our range, you will find detailed information concerning the standards and measures that correspond to it. Of course you can also make use of our advisory services.
