Which Groupset?

Well, you can't dispute that the cable pull of current Shimano kit isn't factored into the design of current after market cable pull discs - although it might be in the CX77.

The extra cable pull does make them more sympathetic to wonky rotors at the cost of a lack of bite, however. I guess it depends if you want BB7s / TRP to feel like cantis or not.

5700/6700/7900 work better with MTB BB7s than with the road version, apparently.

TRP Hy/Rd, which are arguably the best aftermarket solution for cable road levers, work with both old and new pull ratios (by changing where you clamp the cable).
