Steps chain device sacrificial rubber

[Benbenben]

Just noticed CRC had left my chain rubbing on the lower rubber part of the chain device and it’s already pretty much worn away. Is it possible to just replace that small part of rubber. Should of checked it before.

You can adjust the chain device by loosening the 3 bolts behind the spider that hold it on, and rotating forwards or backwards.

Just renew it with 3M mastic.
Clean up the guide, apply and leave to set for a day or so.
