is this because they were really designed for hydro?
No, the alloy Synapse were designed to run with cable pull brakes, you can however run full hydraulic which required even more tweaking.
It's just I had never build/service a Synapse Alloy whose rear disc felt silkily smooth.
Just look at the cable housing (that's the entire length, it stop just inside the chainstay), it's even more awkward with the Promax and TRP calipers.
