Ted, I got pretty excited when I saw your post
The 11-32 as you depict with 43/26 rings just about perfect replicates the 46/26 with my preferred spacing with close to 100 on the top end and around 21 on the low end. However, none of the SRAM cassettes I saw online include the 14 cog :( I just want an 11 speed casette that ends in 32 that has 1 tooth jumps in the highest 5 gears and I will adjust my big ring accordingly. Is it really so hard? *sniff*. -Jim On Sun, Nov 22, 2015 at 6:21 PM, ted <ted.ke...@comcast.net> wrote: > Jim, > > I think you might get the gears you want more easily by picking rings that > get you what you want with readily available cassettes. > Eg. sram 11sp 11-28 with 42/24 rings > 42 24 > 11 99.3 56.7 > 12 91.0 52.0 > 13 84.0 48.0 > 14 78.0 44.6 > 15 72.8 41.6 > 16 68.2 39.0 > 17 64.2 36.7 > 19 57.5 32.8 > 22 49.6 28.4 > 25 43.7 25.0 > 28 39.0 22.3 > Tighter spacing than what you propose and only looses ~1" on the low end.
