They’re designed for use with road levers and so pull the correct amount of cable, and they work gloriously well. Shuddering is a thing of the past and they’re powerful and smooth. As TRP says: “The CX9’s linear pull design is compatible with most lever types and provides huge amounts of stopping power.” I’d have to agree with the second part, and they work just fine with SRAM Force levers. They’re a great improvement over canti’s and about $100.00US.
