That USPS trek looks 100% better than it's original form. Honestly I think the BIGGEST improvement was removing the shimano sticker on the chain-stay and adding the new front fork. I am not a fan of those ROLF wheels just because I never got into that gaped spoke pattern.
Your right, it is no cervelo, but it is one hell of a nicer bike than it was b4. Good job not offing it the few times you were thinking about it.
