Signature Open Back Arm Cups

Signature Open Back Arm Cups Info

The TriRig Signature Open Back Arm Cups deliver a high-value, high-comfort upgrade for triathletes and time-trial riders looking to refine their aerodynamic position without breaking the bank. Molded from TriRig’s ultra-strong ThermoPlast™ material, these cups strike an ideal balance between durability, light weight, and affordability—making them one of the most accessible and impactful cockpit enhancements available.

The open-back design provides a supportive yet flexible platform that accommodates a wide range of arm lengths and riding styles. Paired with TriRig’s textured neoprene pads, the cups offer excellent grip and cushioning, helping riders stay relaxed and planted in the aero position for longer durations. By reducing pressure points and minimizing arm fatigue, these cups make it easier to maintain an efficient posture through long-course racing or structured training sessions.

Featuring expanded mounting options—including slotted bolt holes for additional fore-aft adjustability—the Signature Open Back Arm Cups integrate seamlessly into a broad spectrum of modern cockpits. Riders seeking even greater tuning capability can pair them with TriRig Wingspan Extenders or Speed Concept-specific hardware for enhanced compatibility.
