I inadvertently proved today that Silver shifters can shift 10 speeds, if not mountain or Dynasys (I know nothing about those). I replaced the Bontrager 44/40/26 triple with a Logic on a offset 130 Phil, with 42/28 rings, so I had to change my cassette. For me, this means dumping the cog box onto the floor and scrambling around to find the right sizes -- the collection includes Uniglides, 7s, 8s, 9s, and apparently even some 10s. I found the butt end of a cassette, 3 cogs riveted together on a spider, 21-23-27, which looked just right for the big end, so I put that on. I wasn't paying attention, so I just shoved the other cogs on with 9 speed spacers, and was a bit disconcerted to find (a) that the lockring had to be pushed hard to engage the threads, and (b) that I had to adjust the inner limit screw. The 9 speed SRAM chain shifted fine.
Then I looked more closely and found that I had a home-brew 10 speed: 13-27. That would have been very good news, except that my hub seems incompatible with dished big cogs; the inside of the 27 lightly rubbed the spokes. When I substituted a "flat" big, I could no longer squeeze 10 onto the freehub body. But the Silver BESs shifted the 9 speed chain very nicely across all 10 of the cogs. Given my experience, I will now simply buy some 10 speed spacers (if I can find a source that doesn't charge $7 to $18 per) and a new chain, and build my own 10 speed cassette. I think that the ~2 mm saved by the narrower spacers will more than make up for the absence of a dished inner cog. Anyway, an interesting experience -- 10 speeds with 9 speed spacing on a Shimano freehub.
