Been thinking about this some more. One think about 11 speed that I've noticed is that some sites claim that the cable pull is not the same ratio throughout the travel. Which makes me wonder if certain shifters have to be paired with certain rear derailers. I run the Microshift bar-ends now, and would like to continue using them, but with the uncertainty around cable pull, would they mix with a Shimano derailer? I dunno, maybe should stick with 10 speed, that makes things a lot less complicated. I know in that case I would only need to change the shifter, cassette and chain to switch to 10 speed. That seems a bit more appealing, on second guess.
The other thing is, how to best achieve the gears I want. It's easier to run a slightly narrower cassette if you accept having a bigger jump on your wide-low double. Maybe I should just give up having a 32 or 34 in the back, and just run a smaller bailout gear. The end goal is to keep my lowest gear inches and highest gear inches around where they are now, but bridge some of the gaps in the middle. I can get a Miche 12-29 10 speed, which has the ratios 12-13-14-15-17-19-21-23-26-29 and also a loose 16 and a loose 24, from XXCycle. for $59.53 shipped. Removing the 23 and 26, and inserting the 16 between the 15 and 17, and the 24 between the 21 and 29, gives one 12-13-14-15-16-17-19-21-24-29. With 44/24 the aforementioned modified ratios get you: 95.3 52.0 88.0 48.0 81.7 44.6 76.3 41.6 71.5 39.0 67.3 36.7 60.2 32.8 54.5 29.7 47.7 26.0 39.4 21.5 Current top gear with 44/28 and 11-34 in back is 104.0". Current lowest gear is 21.4. So I give up a little top end, and the bottom end is almost identical. I do use the 104" gear pretty often on road rides but maybe I just need to work on my coasting technique and forget about it. Why do I obsess about this stuff for months before spending a relatively small amount of money? It's a curse. -Jim On Thu, Nov 19, 2015 at 8:33 PM, Ron Mc <bulldog...@gmail.com> wrote: > ps, my favorite 9-speed is 12,13,14,15,16,18,21,24,29 - there is not a cliff > anywhere in here - I'm running this with 42/25 and range is 94 down to 23 > inches > XXcycle has them all - you could start with a Miche 12-25 11-sp, change one > middle and final cog and have very close to what you're looking for - below > 40 inches, drop to your bail out ring. > > > On Thursday, November 19, 2015 at 8:03:34 PM UTC-6, Ron Mc wrote: >> >> Miche doesn't go beyond 29 teeth, but I've built 3 custom 9 speeds and >> love them all. >> >> On Thursday, November 19, 2015 at 6:22:48 PM UTC-6, Richard L wrote: >>> >>> You might be able to build what you want with Miche cassette cogs.
