My right shifter has completely broken and I need to buy new shifters.
The current setup is a 10-speed system using 105's. I appreciate that the new 105's come in an 11-speed option only.
The question is, what is my next best option? I was going to buy a pair of Tiagra 4700's 10 speed, but I have heard that these are not compatible?
Which Tiagra shifters would be compatible with my existing 10-speed groupset?
