Open Back Carbon Arm Cups

Open Back Carbon Arm Cups Info

The TriRig Open Back Carbon Arm Cups bring premium comfort, stability, and aerodynamic refinement to modern triathlon and time trial cockpits. Building on the popularity of TriRig’s Mini Open Back design, these full-length carbon versions deliver a deeper, more supportive cradle that promotes consistent positioning and reduces fatigue during long-course efforts. With more than 200 mm of total length, they offer generous forearm support without sacrificing adjustability or cockpit integration.

Crafted from lightweight, rigid carbon fiber, the Open Back Carbon Arm Cups provide a responsive feel that keeps the rider securely planted in the aero bars while minimizing unwanted flex. Each set includes TriRig’s signature textured neoprene pads—cushioned, grippy, and designed to maintain comfort and stability through vibration, heat, and extended time in the saddle. Pre-installed pads make setup easy, allowing athletes to upgrade their cockpit in minutes.

These arm cups are among the most impactful comfort upgrades available to triathletes. When riders can stay relaxed in the aero position longer, they not only conserve energy but also maintain a faster, more aerodynamic posture throughout the race. For additional cockpit adjustability, TriRig Wingspan Extenders and Speed Concept hardware kits pair seamlessly with these carbon scoops.
