I just found this forum after screwing up my bike. I'm not an experienced biker. I rode my bike a lot in college, an old Diamondback Sorrento, and have been riding it recently a lot, until I tried removing the rear wheel. Big mistake. I was trying to replace the skewer with the one that came with a trainer I just got. Anyway, I've been riding for the exercise, to lose weight, and relieve stress. Plus I just love the feeling. I'm looking into a new bike now, and considering a Specialized Hardrock. I was riding paved trails, then moved more to roads lately because I was tired of running into spiderwebs and other creepy things.
