the only complaint I have is the front derailler doesn't work as nicely as it should - I've read this is a common complaint with the 2005 and earlier models.
I was having horrible problems with my front derailer. So much so, I could rarely change into the big chain ring... lots of rubbing... lots of frustration!

I kept taking it to the bike shop... and they said it was fixed, but it never was.

I finally had someone refer me to a real bike shop that could fix the problem... and now my derailer works perfectly... always smooth... no issues with shifting.

My bike was about to get thrown out... all it took was finding a GREAT bike mechanic to fix the issue.

So... ask around... maybe you can get it fixed properly.
