Signature Closed Back Arm Cups

Signature Closed Back Arm Cups Info

The TriRig Signature Closed Back Arm Cups deliver a major step forward in aerodynamic comfort, stability, and long-duration support for triathletes and time-trial riders. Built from TriRig’s ultra-light, impact-resistant ThermoPlast™ material, these cups offer a rare combination of durability, low weight, and affordability—making them one of the smartest, highest-value upgrades for any performance cockpit.

The closed-back design wraps gently behind the elbow, creating a secure, cradled platform that keeps the rider locked into their aero position even during high-hands setups or extended upward-tilt bar angles. By reducing the micro-adjustments and upper-body tension common in aggressive aero positions, these arm cups help riders stay lower, longer—translating directly into improved aerodynamics and faster bike splits.

Each pair arrives with TriRig’s textured neoprene pads pre-installed, providing excellent grip, vibration damping, and cushioned forearm support across rough terrain or long-course racing. For athletes seeking additional cockpit tuning options, the Signature Closed Back cups pair seamlessly with TriRig accessories like Wingspan Extenders and Speed Concept hardware kits.
