So I currently have 11 speed mechanical shimano 105 and for reasons I need to/want to upgrade to electronic shifting. However my frame isn’t di2 compatible so I’m forced to switch over to sram. I’m trying to change as little as possible. Is there goin to be any issues using the old free hub with a 12 speed cassette or the old crankset. I understand it’s not going to be perfect but I don’t want to have to replace everything if I don’t have to. Thanks for help/advice!
