Compressionless brake housing is quite stiff and doesn't tolerate tight bends very well. TRP recommends using it for their mechanical disc brakes (Spyres) with drop bars but also recommends use of a short section (4-5") of standard spiral wound housing to go from the brake lever or brifter around the tight bend from the lever to the straight section of the bar. Then they recommend adding a double end ferrule and using compressionless housing from there to the brake caliper where the bends are wider.
