I have a mtb with roadie bars. I have 10 speed Ultegra shifters with a 10 speed mtb cassette (11-32). I had to put a 9 speed XT mech on it as no 10 speed mech would work.

It all works great!

But, I want to change to mtb bars for the summer and want to know what 10 speed mtb shifters to buy.

What will work?
I assume 10 speed Dynasys won’t work, but what will?

Pretty sure you can get Tiagra flat bar 10sp road shifters from Shimano? Would still work with your 9sp mech, don’t think 10sp mtb ones will (but I could be wrong).

Ultegra 10 speed flat bar £60.00?

Linky.

Dp.

You’ll need shimano R770, 780 or Tiagra 4600 flat bar shifters. The 4700 flat bar shifters will not work.
