I am looking for some 7x3 Shimano shifters and V levers so that I can go v-brake with separate levers and keep the 7-speed set up. The Stx's I have amasingly work with my XT vbrakes but I want to do this change properly. If someone can come up with a swappy it would be nice, perhaps XT LX in the mix. My STX set up is 1991ish 7x3 speed combo brake/gear a matched pair that look at first glance like XT and haven't seen a lot of work.
