Ted's remark raises an interesting question. I for one didn't think that so very closely spaced cogs might require fine tolerances that exceed the everyday capabilities of shift-by-cable systems, what with friction changing with wear and dirt.
So, question: Is it generally true that above 10 speeds or perhaps 11 cable systems don't work very well, or at least, shifting quality degrades quickly compared to systems with fewer cogs and wider tolerances? I recall using a Cyclo Benelux pullchain rd* to shift 2 cogs hacked onto a SA AW driver; to take an extreme case, I can't imagine that rd indexing 4 cogs let alone 12. It did index 2: all t'way for'ard and all t'way backward. (Kidding.) So, again, to sum up: do 12 and 13 speed systems require and lock you in to electric shifting? That is a question, not an implicit value judgment. On Tue, Nov 29, 2022 at 11:14 AM Ted Durant <[email protected]> wrote: > ... > Exactly!
