Yeah but the issue is the step between gears can be kind of steep on the 2x10, I sometimes find myself bouncing between two gears because neither one is quite comfortable. For me the 2x10 with brifters is acceptable but not ideal though it beats the heck out of a 3x10 with bar ends or thumbies... I ponder pushing the rear cassette to a 11-40 but think I'll pass and in hind sight I should have explored a 2x11 setup but I'm too heavily invested in the 10 sp rig to change now.
