I cut away a small section of the rubber protecter and replaced it with thick tape. Some frame protection tape I had in the parts bin. The chain rubbed a groove onto the tape. But didn't damage the frame.
I called the manufacturer..... they will get back to me in about 2-3 months. I asked on a Canyon specific forum and guys are saying even a 30T round will cause chain rub. Oh well....I guess back to 32T oval. And some leg extension exercises in the gym.
Anyway does the derailleur look too stretched out here? This is with the 32T oval.
