This is a 2010 Trek 3-Series bike with a 21" frame. I bought the bike in October of 2010 from Golden Bicycle's in Auburn to help me get around while my license was suspended. I rarely used the bike in this time. At most i put 40 miles on it. "You can tell by the picture of the tire". There was one "tune up" done about a month after the purchase as soon as i got it broke in. This thing has literally sat in my apartment since then collecting dust. It comes with a bottle holder of course, and an L.E.D. headlight and tail light. I have over $500 in it but am willing to sell it for $225, which is an absolute STEAL. The only trades i'll accept are tools, and hunting and fishing objects equal to value. Contact me and we'll discuss options.
