I know This is a single speed website but I need advice on the shimano ultegra 6800 11 speed I'm running on my cross bike. No matter how much adjusting has been done, limit screws, tension, there is still rubbing coming from the front mech when I'm in the hardest gear. The local mechanics have shown me that it's due to flex on the chain ring when under pressure and because the ultegra is set up so compact. Is there anything I can do or am I stuck with a new noisy cross bike?
