Ohhhhh... If you're not using a later Suntour mech, that's the problem right there. Try one of the various XC models, a Pro by preference, with a 4-prong Winner. That should clear it up. FWIW I don't think Winner freewheels shift very well except in index mode. Somewhere in the forum archives, there's a Rosetta Stone with the info needed to build a Hyperglide cassette with Suntour index spacing. That would be handy to have. It would be too much hassle, but the Command Shifters are just *so* nice.
