Kurt--

I have at least four wheelsets with 6 & 7 speed DA Uniglide, and one old DA AX that works just fine with Uniglide. Sprockets are fairly plentiful here, too, though I'm always looking for DA variety, especially in 23 to 26 tooth ranges.

One of the best bargains out there are old DA hubs laced to Mavic tubulars.
