I'm not able to setup 53/39 Q-rings on my road bike with Shimano(6600) E-type derailleur. It always ended up with chain rubbing the cage. The cage has a groove along the chain and the chain moving vertically makes it very difficult to get the chain centered in the cage.
Are E-type derailleurs compatible with Rotor Q-rings? Which derailleurs are compatible with Q-rings? TIA.
