Open Back Carbon Arm Cups

The TriRig Open Back Carbon Arm Cups are designed to take your aero comfort to the next level. Building on the success of our Mini Open Back Arm Cups, these carbon versions elevate every aspect of performance and comfort. With a total length of over 200mm, the Open Back Carbon Arm Cups provide support and stability for riders seeking the perfect balance of aerodynamics and comfort. Featuring the same textured neoprene pad that has been so popular with our original arm cups, these carbon scoops ensure an optimal grip and cushion, keeping you comfortable even during long-distance rides. Each set comes with pads pre-installed for an easy and seamless setup. The Open Back Carbon Arm Cups offer one of the most substantial comfort upgrades available for triathlon bikes. The more comfortable you are, the longer you can stay in your aero position, which means faster ride times. These cups are a game-changing upgrade for anyone looking to improve both comfort and speed on the bike. For enhanced cockpit compatibility, add Wingspan Extenders to your cart.
