needs another beer
i'm very interested in buying a mountain bike but honestly i know nothing about them. i plan on riding to work everyday (10 miles each way) but i also plan on taking it up into the mountains at least a couple times a month. i've heard that frame size is a big deal, i'm 5'10" and weigh 175 pounds. what kind of things should i be looking for? i'll probably be looking for something used, right around the $300 range.
