I'm thinking of switching from my 38T front/24T rear to XX on my 29'er.
When using Sheldon Brown's gear calculator, I see that to be as close as possible to my 2x10's 24T front/36T rear combo, a 30T XX1 ring seems to be the best option, although it still seems to be closer to 2x10's 26T front/36T rear.
On my 2x10 I use the 14-16-18T rear cogs the most, almost never the 11-12T cogs. So the XX1 30T seems to be suited the best theoretically.
Who has some experience with a 30T ring, compared to above 2x10 setup? Does the 30T ring still offer enough speed on the flat, and is the jump from 10T-12T not too big (gear spread) ?
