is this at all possible? what exactly would you need? my mates after going from 3x9 to 2x10.....as cheaply as possible?
he doesnt use granny ring, nor doesnt use the large ring (but does occasionally for road use)...so ditching the granny ring is an option....
would it mean next chainset? cassette? etc? or just new front fronts? and also do you go about doing so?
thanks!
