i have a 8 speed rear being 6 cassete and two loose sprockets...
the gearing goes from 28 down to 11... would there be any advantage in me adding another sprocket to make it a 9 and would i have to do anything to the frame on the bike for it to accept it...
if it is possible i am looking into replacing the rear with a 9 speed cassete i have paralax wheels if that helps..
