I'm 6'-2", 255 pounds and I'm happy to have just discovered that a whole realm exists by and for the creature known as the Clydesdale. Apparently, based on my physical characteristics (once I start riding again), I'll be a Clyde myself. I used to be a bike messenger in DC, have messed around with some offroading on rented bikes, and have done a fair amount of road biking but I'm ready to by a new bike and start riding XC more seriously. I really have very little knowledge of what ride would be right for me. Narrowing down my options is the fact that I can get a great deal on a bike through my Father-in-law and that his shop carries Marin and Trek. The pricerange I have in mind and my pre-conceived riding style have brought me to the Trek Liquid 25 and the Marin Rift Zone. (I think I want a FS rather than a HT because I'll probably occassionally be addressing terrain appropriate for such a rig. I'm also not scared of riding for extended periods of time and figure that the comfort a FS bike would provide would be worth it. Additionally, I don't plan on racing and so I'm not concerned with the loss of speed an FS might cause.) Can anyone tell me if either of the models I'm looking at would be better suited for a soon-to-be-Clydesdale such as myself? Any other points someone may have that I should consider would be greatly appreciated as well.
