Closed Back Carbon Arm Cups: Maximum Support, Minimum Weight

The TriRig Closed Back Carbon Arm Cups are designed to deliver unrivalled aero comfort and stability. Measuring over 200mm in length with deep arm wrap, they offer more surface contact than any other production cups available—keeping you locked in and secure mile after mile. Crafted from lightweight carbon, they combine exceptional strength with a feather-light feel.

Engineered for triathletes and time-trial riders, the closed-back design supports the elbow and excels in high-hand or upward-tilt positions. This keeps your body relaxed, stable, and firmly in the aero position—so you can ride longer, faster, and more efficiently.

Each pair comes fitted with textured neoprene pads, providing the ideal blend of grip and cushioning for long-course comfort. With their unique combination of support, strength, and low weight, the Closed Back Carbon Arm Cups are one of the most effective aero comfort upgrades you can make to your bike.
