Cassette just needs to be functional with at least one good side of the sprockets left. A 26T sprocket would also be handy in the mountains with my 52/42 chainrings - only have 23T currently.

Dang. I just sold a 13-26 7-speed uniglide cassette last fall. It had been sitting in my parts bin for a year and I didn't think I'd ever need it. I'm sorry now. Phil G.
