Product Description The SM-CD800 Chain Guide by Shimano - Increased safety for mountain biking The Shimano SM-CD800 chain guide is available as E-Type, D-Type or for ISCG 05 installation. It is only compatible with MTB 12-speed cranks.

The chain guide is made of synthetic resin and can be easily adjusted with a screw.
