Mixing Shimano and Suntour

[raymondluxuryyacht]

Thanks for the link Tommy. I seem to recall even some of the non-microdrive 7 speed suntour cassettes had that weird spacing. I can't make out the cassette on right on that web page, but I think its a six speed non-microdrive rather than a 7. I think both 7 speed micro and non-micro were weirdly spaced.
So lesson is 8 speed suntour micro = ok, 6 speed (all nonc-micro), 7 speed = weirdly spaced.
