Working on the modern today, but I'm stuck with the gearing.
Long ago I bought a set of Sun Microshift thumbies in 3x10 fashion, but I never actually used them. Currently I am trying to get them to work with my 3x10 Deore XT drivetrain. The rear one (first one I tried to set up) simply won't work properly. It won't engage either the top 2 gears or the lower 2 gears, depending on how I adjust the cable. It also doesn't fully engage the last gear it is willing to go to.
Basically I only get around 7.5 gears, despite clearly feeling a 10-speed index (9 distinctive clicks).
Friction mode doesn't help either, except that it allows better adjustment in the gears that were rattling and jumping in index mode.
All the parts are brand new, the cables have no friction whatsoever, the rear mech (XT M780 shadow) only has one option for cable routing.
Anyone have any ideas what I could do? I'm starting to think that there's a leverage issue which could mean that these shifters are for SRAM drivetrains.
