Suntour thumbies, cant even remember the model, but they can do 7 or 8 speed, not sure if they work with Shimano? Never used them, been in a box of stuff for years.

They're XC Expert, I have two pairs, plus a pair of XC Pro just fitted to my S-Works '94 FSR. They're running with a late 90s XT mech and an 8-speed SRAM cassette and shift surprisingly well, i.e. no skips once well adjusted.

I had - and will have again- XC pros on the Montage and they were awesome. No skips, nice and comfy too.

Old topic brought back from the dead to ask.........

Would these Suntour Experts work with an XTR 900 series 8spd rear mech???

I could never get mine to work "perfectly" with a Shimano cassete.
But they're still the nicest thumbies to use.

SunTour thumbshifters work pretty well with both 7- and 8-speed Shimano-spaced cassettes. SunTour cassettes are spaced at 4.8mm for half the block and 5.0mm for the other half; Shimano 7-speed is 5.0mm and 8-speed is 4.8mm for the whole cassette. So, get things spot-on in the middle of a Shimano cassette and they'll still be close enough to shift okay at the ends. Remember that Kona used to spec bikes with 8-speed SunTour thumbshifters and 8-speed Shimano cassettes and no-one seemed to complain.

I'm currently running SunTour XC-Pro 8-speed thumbshifters with a late-90s XT rear mech and a SRAM 8-speed cassette and the whole lash-up works a lot better than I ever expected it would... at least when it's clean :wink:

In my case, tt wasn't the Suntour/ Shimano mix; The frame had a bent rear mech hanger [cough!] :lol:
Using indexed mode, the Shimano thumbies compensated for it better than the Suntour did.
