I finally took mine off this weekend after trying to solve the problem for almost two years. Like you said, any little bump would make the fender rub.I have had my Rook for 1 1/2 years have had a horrible time with the front fender rubbing. Any time the wheel gets bumped, it causes the fender to shift and it rubs. I decided today to take it off. Other than that, I love the bike!
