You likely cannot put a road 10, 11, or 12 speed cassette on an 8 speed hub (35.4mm), and 9 speed (36.5mm) is pretty iffy also. It is possible that the 8 speed cassette is on a wider hub with a spacer, but you need to check. Shimano 11 speed mountain cassettes fit 9 speed width hubs, so you can get at least 10 of the cogs on an 8 speed hub.
Just as a reference point, I shift an 11 speed Dura Ace cassette with a downtube Silver1 shifter with Dura Ace 9 speed derailleur. I kind of prefer the long lever movement so that I don't skip any of the closely spaced gears. I also prefer the looks of the Silver1 over the Silver2. I keep threatening to grind down a Silver2 and put a Rustines Gum Shifter Cover on it, for a little less throw without the bulk of the Silver2 shifter.

The spouse wants more gears and the fastest way to do it is to get him a 10- or 11-speed cassette and a friction shifter since his Breezer Downtown EX came as a 1x8. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
