I thought the TRP Hy/Rd used hydraulic pistons on both sides of the caliper, so both pads move? I can't think of a single hydraulic or hybrid cable/hydraulic caliper which uses a static inner pad.
Woooo, retro. OK, in the past people have done silly things like build single-sided hydraulic brakes, but now we know better and don't do things like that.
