I would appreciate some feedback on what folk feel would be a fare price for me to ask for my 1997 Specialized Rockhopper when I advertise it for sale? The bike is I believe all original and the condition is probably as good as it gets for a 24 year old bike? The frame is 18" from centre of crank to top of seat tube, which is how I believe Specialized measure their frames. I picked the bike up 2nd hand approx. 15 years ago, as I just love the team red livery and was full of good intentions to get myself off road a bit. However it is a bit small and I never made good on those intentions due to work and other excuses. Instead I have just stuck to the road and my Hybrid for exercise, with the Rockhopper living in the spare bedroom unused ever since. Thanks in advance.
