That being said I have experienced riders getting a new charge out of a new frame (even a used frame new to them), a new set of a wheels, a new pair of shoes, or a new crankset.
It probably is purely mental, but if that get's them up a few minutes early or on the bike after a shitty day at work when they'd usually say, 'sod this.' then, who can bitch?
I surely look like a the BIGGEST fred out there with my Dura-Ace and high Castelli shorts on Sidi Genius. I have a new Eddy Merckx frame with a Campy headset and crank that I can't even bring myself to build yet because I'm so out of shape.
At least I'm having fun with it.
