Description
The SHIMANO STEPS CD-EM800 chain guide is a part dedicated to the transmission of electric-assist bikes equipped with a SHIMANO STEPS drive unit. Designed to accompany 34, 36 or 38-tooth chainrings, it helps stabilize the chain at the drive unit and limit derailments during changes of pace, relaunching or passages over uneven terrain. Ideal for replacing a worn or damaged chain guide, it helps maintain smooth pedaling and a smoother drivetrain on a daily basis.
Benefits for the user
By holding the chain more securely around the chainring, this chain guide for EABs reduces the risk of derailment and improves traction continuity, especially when the electric assist is delivering torque. It provides greater peace of mind on both sport and utility rides, by reinforcing the stability of the chain line at the motor.

Expert advice
Before ordering, check the number of chainring teeth (34/36/38) and confirm that your SHIMANO STEPS configuration includes a chain guide mounted on the drive unit. When replacing, check the condition of the chain and chainring: a worn chain or damaged chainring can increase the risk of chain jump despite a new guide bar. After fitting, carry out a test run over a few kilometers and recheck tightening to ensure optimum hold.
