I have a spare Colnago Mexico 6 arm 36 tooth chainring surplus to my needs. It is NOS and might just give a 6 arm (crank) owner the chance to actually use the crank - not just bask in its beauty behind glass or wherever you hide rare bike parts. Keep one fresh if you wish to retain investment value and ride on the other. 36 teeth will get you to the Sunday cafe slow enough for even the most desperate poseur to be noticed. (I've always leant towards 'slow cars and fast women' - crikey! I've been spending too much time with Ben K!!!) Anyway, prefer a trade as I have too many projects that fall short of a part or two.
