I got a set of Suntour Command shifters cheap. They're unused, in perfect shape..but are for Suntour 6 speed indexing. There's a switch to switch the indexing from "6" to "F6" which provides lighter indexing, but not pure friction.

I've read in the past, somewhere, that you can take the indexed shifter apart and file down the detents that make it index...I've searched and searched and can't find the thread I saw it in.

Does anybody have a link or know what I'm talking about?
