Nerrow chain crankset?
I got one of the HG 31 cassetts, they do not have a jump from 34 to 28! It jump down to 26!
apearantly the only way to get the gears I need is to use a 9 speed cassette. And new chain.
But do the chainrings need to be closer together for the nerrower chain??
I am going to use an old Biopace crank set.
