Dead Ultegra 6600 shifter (RHS)
My right hand side shifter (Ultegra 10, 6600) is dead, the ratchet mechanism is missing pulls, so I need a replacement. Any advice on what way to go? Most new shifters are in pairs, hard to find a single one, especially an older tech.
Is new Tiagra or 105 as good (and compatible)? What about older Dura Ace 10 speed, etc? Drivechain is 10 speed, mostly Ultegra 6600 with Dura Ace rear mech. Any other suggestions?
