The modular chain guide SHIMANO SM-CD50 provides even under the most difficult conditions for secure chain hold. Suitable for Shimano SAINT FC-M820/825 and ZEE FC-M640/645 cranks.
The modular chain guide from SHIMANO is robust and efficient. The rider can mount one, two or no chain guide depending on the course and use. The chain guide has a minimal impact protection to protect the chains and chain ring from shocks. And thanks to the replaceable silencer, there is less distraction from noise, so you can better concentrate on the ride. In addition, the SHIMANO modular chain guide ensures an extremely stable and quiet drive with the SHIMANO Shadow+ rear derailleur.
