Speaking for myself only Silverfox, i'm not a lover of Trek. I really don't know why.
But, i always say when someones looking for a bike but not sure what brand to go for...they're all much of a muchness...in a good way. I even have a Trek, albeit a 7100FX hybrid, which is certainly not in the same vein as the madone.
Not having had a higher end Trek, i'm certainly not qualified to say one way or the other...i just think its about personal preference. Perhaps Trek is just one of those brands that people like to knock, but it doesnt mean they're a bad bike.
I'm rambling....lets put it this way, if Trek really were so bad, we'd have certainly heard it on here. To the best of my knowledge...we havn't.
