Dura Ace 7700 (with American Classic RD205 rear hub) Broke Shifter. Upgrade Options 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? 

Any suggestions?
If you want to keep with 9-speed and Dura Ace level, options are following:


New Old Stock. You can probably find and exact replacement on eBay or some shop that specializes on old parts.
Campagnolo shifters, either 10-speed with Hubbub cable routing or Shiftmate 2 or 11-speed are compatible with Shimano derailleur and 9-speed cassette.
