MudStop the Bosch bearing protection system

MudStop, a bearing protection cover developed by VeloLab in Belgium. It has been designed to offer a better level of protection than the Bosch bearing “seal” cover.
The MudStop cover fits behind the front sprocket providing excellent protection for the main motor bearing in the Bosch Active and Performance Line / CX motors. (Not suitable for Bosch Gen 4 motors)

The MudStop cover fully shields the main motor bearing and fits over the outside of the right hand motor cover, making an effective barrier against mud, dust, grit and water. This can effectively prolong the life of the main motor bearing.

Please note: If you have the original Bosch motor covers a slight alteration is required. Please see the last page of the instructions below. You can purchase the tool to do this here:
