I bought this bike for parts, so here is the frame, size medium 17.5," 110mm suspension in excellent condition. Came stock with 120mm fork. The previous owner was the original purchaser who stated that it had no more the 2 dozen rides on it. It definitely matches that claim. All bearings are smooth with no play, rear Fox RP2 DRCV shock functions like new. Comes with the stock FSA headset including crown race. Uses tapered 1.5-1 1/18" steerer forks unless you find a reducing crown race. Uses old standard 10x135mm rear axle wheels, includes the stock Bontrager rear skewer. I am cleaning out my shed and have a ton of bike parts if interested for your build. This could also be a great high quality, yet a cheap replacement for your hardtail. Check out the Trek website here for frame specs/details: http://www.vintage-trek.com/Trek-Fis...2010fisher.pdf. This is the medium, has 23.62" effective top tube. I would gauge to roughly fit someone 5'6"-5'10."
