Sharing a rig means moving the pedals, and moving the pedals usually means an Allen key, a torch and ten minutes under the frame. Nobody does it. The taller driver ends up cramped or the shorter one ends up pointing their toes, and the rig quietly becomes one person’s.

This puts the pedal deck on rails. An adjustment handle releases it, the whole assembly slides fore and aft, and a dual locking system clamps both sides rather than one.

That second detail is the one that matters under braking. It sits with the rest of the hardware mounts we carry for extrusion rigs.
