Which rear mech?
Had a minor catastrophe at the weekend which involved wrapping the rear mech round the rear wheel of my Specialized Allez. It was a Sora rear mech. It will need replaced. I think the wheel iand frame are probably OK. So my question is would there be any point in replacing the rear mech with an upgraded 9 speed rear mech or just stick with a like for like replacement? If I go for an upgrade would that mean I needed new shifters too?
