Okay, that's good to know. Also, upper roller - remove? I don't know what has been done to the bike, as when I got it it has had SO many parts changed. The obvious things are easy to see, but for instance when looking into changing the headlight, I noticed that it was already unusually white and bright - possible already changed. Might tear it apart to see what has been done - you always need to know your bike! Cheers, Chris!
