Seen em go for between 1000 to 1500 on retrobike, Steve Worland sold his on here but not sure what it made in the end…being an ex team bike it'd have a few extras that 'regular' RC100's wouldn't have, extra milling, lighter weight etc, it would have been running a few RC200 refinements too as was the whole R&D with Pace. Can see that the seat clamp is a newer RC200 development, but this may have been done a while afterwards.
All in all, you could get quite a tidy sum, but then would you live to regret it? I regret not having the cash to buy it off you myself
Good luck whatever you decide
Like Pace Mountain Bikes, own one, pour yourself a mug of tea, pull up a chair and tell us all about it at...http://retro-pace-mtb.wikifoundry.com/
