Hey all,
I am wondering if anyone can help out, I have had my bike serviced and they suggested replacing the rear main cog and a couple of other due to wear.
I have got the bike back and unpowered it's running fine, but under power it's pulling the chain around the drive cog which then pulls the rear derailier tight. This then pulls back straight unwrapping th chain from the drive cog.
Any suggestions on what this may be?
All help appreciated!
