I’m currently putting quite a lot of miles on an older Canyon F10 carbon bike equipped with Dura Ace 7700 shifters, derailleurs and brakes. My wheels are American Classics with a newer RD205 hub, which according to American Classic supports 10/11 speed cassette.
Unfortunately, my right shifter broke and I’m quite short on options regarding 9 speed shifters. I could go with Microshift, which would be a significant downgrade as well as Sora.
I really love that bike but it’s a bit old for a complete 11 speed upgrade.
If going with 10 speed 105 5700 is the difference in shifting in comparison to 7700 big?
