AFAIK there are no special requirements of the frame, you just add the p-clip thing to the NDS chainstay. It came off a completely unspecial alloy frame, so I think any steel frame would be fine. The chain stay has to take a rotational force, but I can't imagine it's bigger than your weight on it, and the actual braking force is through the dropout.

The P-clip pulls down on the chainstay. Given how little torque it takes to lock the rear wheel, it's not a big load; if your chainstay can't take it, you have bigger problems than brake torque reaction 🙂

Very true! Presumably the actual retarding force on the bike i.e., the horizontal force, is though the dropout though, as it is with all brakes.
