toying with the idea of upgrading my specialized epic but as its heavilly upgraded i dont know its true second hand value. Its an 07 epic comp thats only been used for racing in the last year as i have an enduro for general trail riding. Its got bontrager carbon bars and stem, juicy ultimates ( used twice ) noir carbon cranks ( used about 6 times ) carbon seat post and ti railed seat. X0 grip shift and rear derailer. Not ridden since front and rear shock service and rear pivot bearings replaced. Estimated cost if new would be around 6 grand plus. I have no idea how much to ask for it.
