Suntour XC Expert Shimano compatable?
This auction claims XC Expert is Shimano compatable:
https://cgi.ebay.com/ws/eBayISAPI.dll...ADME:B:SS:US:1
I bought a ~1994 XC Expert Microdrive rear mech to replace my old XC 7000. I have yet to install it as my road and commuter bikes' repair takes priority.
Any truth to this?

I'll bet you anything it isn't. The XC/9000s and Superbe Pros were designed for Suntour Accushift freewheels, which are spaced differently then Shimano HG or IG.
I'm not sure if the addition of a Shimano lever into the mix might get it to work, but chances are it won't. I've yet to get anything Suntour to properly index with Shimano.
P.S.: Be wary of anyone promoting Suntour/Shimano compatibility - I've seen a few shops say that the two are compatible just to sell you some old stock.

i have 7 speed deore thumbies on my townie, with a suntour turd derailleur from the early 80s, with a 7 speed cassette, not suntour. those thumbies always accidentally revert indexing, and it shifts fine, so go figure.

I've got 2 SunTour XC-Expert rear derailleurs and I tried one on my Masi with a new 6 speed Winner Pro Freewheel and Superbe Pro indexing shift levers. I couldn't get it to index very well on the 6 speed setting, it was a little better on the shift lever's 7 speed index setting but still not very good. I read somewhere that the XC Expert was designed to index with Shimano now I'm beginning to wonder if it's true. I like the longer cage on the XC Expert rear derailleur but maybe the pull is a little off to work with the Shimano cog spacing. I'm a little baffled right now.

Accushift spacing is the same as the spacing on Winner Pro 6 and 7 speed freewheels as far as I know. In fact, my touring bike has a Winner 13-30 7-speed freewheel and an X-1 Suntour rear derailleur and it indexes really well with my Suntour Superbe Pro indexed shift levers.
