I've been lurking here for a few weeks and learned quite a bit from you all. I'm in my late 30's and in meh shape. I'm about 10 lbs over my optimum weight. I recently got back into cycling after giving it up a decade ago due to some herniated discs in my lower back. After riding my brother's loaner bike daily for a week, a GT Backwoods MTB, my left leg started to get numb again (like it did way back when I had my back problems). So yesterday, I bought a Trek 7.2 FX. Nice bike. It sits more upright for me and since I do all my cycling on paved paths, I hope this bike will serve me well.
