The 700x32c tires look and feel more solid for rough roads. Also the over all feel of the bike is solid. I'm sure I don't notice as much. If you want a super light roadie rig look elsewhere. Sweet Reynolds steel.
Welgo pedals work surprisingly well.
The bearings throughout feel cheap. Those used to XT or XTR will feel a difference. Cheap paint came flawed in a few spots. Put slicks on it, throw it on some rollers, and get fast for the summer. Then, when you're done roosting your friends, put those cool Ritchey knobbies back on it, and try that euro thing called cyclocross.
