I've currently just bolted it on the bike, however when i was adjusting the Upper limit, I attempted to push the derailleur all the way over to line it up with the last gear of the cassette and I was surprised to fine the first jockey wheel hitting the gear. I checked the documentation for the derailleur and it says that it can accomodate a 28t as a maximum size. I have yet to set up the shifters and chain. Do you think this problem will resolve itself once the derailleur is under chain tension?
