I can work out a nice shifting pattern with the standard crankset and the 11-34 cassette, but I can't make it work out well with the 12-25 and a 28-39-50 up front. All the jumps from crank 1 to crank 2 are in the 25% range.
Thanks for letting me know that the 34 cassette would require a new derailler. I don't really want to do that. Can I get away without if I only go to 12-27?
I know that our hills are mere bumps, but at my level of training they are still hard!
Let me do the math with the 12-27.
