    does anyone know how hard it would be to change a 6 or 7 speed bike to an 8 or more speed, obivously new wheels but what about spacing for the axle btw its an early 90,s reynolds 531 steel bike that i really like and would like to upgrade eventually

    you can get shimano 105 8speed downtube shifters and Dura Ace 9speed shifters. if its 1990s frame you shouldnt have to spread the dropouts too much. most would be 4mm.

    I wouldnt call it hassle but STI makes it expensive.

    Its very easy,instead of spreading the frame I'd recommend removing non driveside spacers and dishing the wheel,dont know how much you want to replace on the bike,if you go with 8 speed both mechs and the chainset will work,if you go 9 or 10 they wont.
