I’m building err, something 😉 , and I’m now thinking about the gearing. I’d like 3 x something (ok, maybe 2x something) – either way it’ll need to sit on a (normal everyday) XT M756 hub, and it’ll all be tugged about by bar-end shifters, but other than that it’s kinda all up for grabs
The starting point is a couple of assumptions …
I’m assuming that the Shimano 10spd and 9spd cassettes have the same overall carrier width (so the 10spd block will sit on my hub fine), but just have different cog spacing, so I could use my current 9spd bar-end shifters on friction-mode with a 10spd cassette, the relevant mechs, M780 10spd chaninset and 10spd chain.
I’m also assuming that road 10spd and MTB 10spd is the same spacing, so if I really, really miss indexed shifting, I can just chuck on a set of Dura-Ace 7900 10spd bar-end shifters down the line.
… but, are those assumptions right?
😕
