I have a Quattro pro much of which is in superb condition. Especially the frame. All the group set is original XT and there is probably less than 200 miles on the bike. Some parts have been changed. The rims are now mavic having been rebuilt on the original hubs after one was bent. The steel seat post and handle bars are replaced with trek ea50/70 alloy the bars are mid monkey. The seat is also replaced and the cables have been renewed. Are these worth anything in this condition?
