Hey everyone,

It's recently come to my attention that my front gearbox (err, excuse me for the car lingo) has had trouble upshifting, especially from 2nd to 3rd gear. Occasionally it happens going from 1st to 2nd, but it almost ALWAYS happens when going from 2nd to 3rd. When I look down to see what's wrong, it looks as though part of the chain catches on, but can fully make it on because of the front gear cover (which is a Shimano SIS). However, I have noticed that if I make the first revolution when changing gears slower, it does work better; however, that takes away a lot of momentum.

Does anyone have any idea how to fix this problem? I've been thinking about taking the gearhead off, but I don't know if that's the problem/if it's the right thing to do or if that's even what I should do in a situation like this. It's also an odd situation seeing as the bike is almost brand new.

What do you guys think is my problem and have any of you had a similar difficulty?

Shane

P.S. Oh, and if anyone was wondering, this is on the 4100.
