Can we get a thread going to list DA 7900 pull ratio compatible brakes, preferably with weights?

BR-7900 are the obvious ones, spec'd at 294g
TRP R979s are claimed to be 250g / 260g (SL vs EQ versions)

What else is available?

The ratio is not that much different that it really matters unless you have really small or weak hands.

IMHO if you're riding aluminium rims or on the flat then it's a bit theoretical to bother about this stuff.

But if you're riding up and down the Stelvio then it's better just to stick with the DAs, since they will save you much more time on the way down than they cost on the way up.

Apparently the TRP R879 is also DA-7900 compatible (139g / caliper).

Revl by the Hive. 115 per wheel. Braking is on par or better than DA7900. One downside is that they may not be ideal with very wide rims although I have seen people using them with the newer Enve wheelsets.
