Which Groupset?

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

Because their cable pull is similar to Linear Pull.

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).

I wasn't really considering Hy/Rd - it's a half way house solution. I can see why people like it though.
