hi i just got a tandem which came with grip shifters and a 7 speed set up (inc. a shimano back hub). i want to swop them with an old set of shimano xt 8 speed shifters.
can i just put a new, 8spd. cassette and chain on and change the shifters or is it more complicated than that? sheldown brown (rest his soul) says i can run a 9 spd casette, but just take one cog off. has anyone tried this or does anyone know how it work in practice? i cant see how you could fix it to the hub.
any advice appreciated, i am very new to the world of tandem mechanics.
