just pulled my old gt out of the shed, need to sort it properly this time! (i stripped it and rebuilt 3 years ago). now i need some parts. its a 1992 karakoram in tequila sunrise paint, i need a front mech and chainset. anybody know what i need to be looking for? its got a 7 speed cassette, is there a part number for 7 speed compatible chainsets? i dont intend to do anything too strenuous on it, just want to get it rolling, i've had it since new! any advice gratefully received.
