At just 110g with included bumper it’s the lightest chainguide in its category. This chainguide was designed in cooperation with 4X World and European Champion Michal Prokop.

Available in either ISCG or ISCG 05 fittings it should be installed directly to the frame. If the frame is not equipped with the ISCG or ISCG05 system, then use the included adaptor.
