The cable cam (a.k.a cable fin) is a swappable part of the Jab derailleur that allows it to shift flawlessly with most 1x cable actuated drivetrains. Each unique cam controls the motion of the derailleur for each individual shift, matching each shifter index point to each cassette cog position.
The cams are made using state-of-the art 3D printing technology! They are 3D printed from Nylon PA12 material on HP Multi Jet Fusion 3D printers, and are extra thick so they won't bend or crack.
