I have a 2015 v3 flux with a 2x10. I want to swit h over to a 1x11 or 1x12 if possible. I can do the work, just need help in figuring out exact items needed. Ex: whi h rear deraileur, medium or long cage, which cassette, crank and chainring. I currently run full xt. Thanks.
Aloha.
Before going through all the trouble, what is your motivation to switching to a 1x11 or 1x12 setup?
If it is range, you'll want to do some math before switching. Your 2x10 set up gives you a certain range and if you are wanting to keep that range, you will need to consider that.
All 1x setups have a compromise on one end or the other based on the cassette and which size chainring you use. Though with the new E13 and SRAM and Shimano 12 spd cassettes, you're in much better shape than before.
That believe it or not, I still run my Flux V3 with a 2x11 setup that has more range than any 1x setup could ever give me. My chain rings are 29/20 (with old school Race Face Forged crank set) and a 9-44 11 spd setup. People tell me they can walk faster than I can ride up some of those ultra steep hills. But I love the challenge of saying I've climbed it and not have to walk it.
I do have other bikes that run 1x11 and 1x12. They are all sleighted more towards climbing and less on the high end side (spin out around 22-23 mph). Especially on LONG, epic rides, I want to be able to climb and high speed isn't as much of a priority. That's just me.
