Signature Closed Back Arm Cups: Redefining Comfort and Support

The TriRig Signature Closed Back Arm Cups are engineered to take aero comfort to the next level. Made from ultra-light and durable ThermoPlast™, they combine strength, performance, and affordability—making them one of the best-value upgrades for triathletes and time-trial riders.

Unlike standard arm cups, the closed-back design extends behind the elbow, providing extra support and stability. This is especially beneficial for riders using high-hands or upward-tilt positions, helping you stay locked into aero while keeping the upper body relaxed.

Each set includes textured neoprene pads for superior grip and cushioning, ensuring long-lasting comfort. By reducing strain and improving stability, these arm cups make it easier to maintain your aero position for longer—directly translating into faster, more efficient rides.
