Signature Open Back Arm Cups: The Ultimate Aero Comfort Upgrade

The TriRig Signature Open Back Arm Cups are designed for comfort and performance. Crafted from our ultra-strong, lightweight ThermoPlast™ material, these arm cups offer superior strength and durability at our most affordable price point ever.

Triathletes and time-trial cyclists who use our Signature Open Back Arm Cups stay comfortable in the aero position longer due to the textured neoprene pad that provides the perfect balance of grip and cushion. These cups also feature an increased adjustment range, thanks to additional mounting points and slotted bolt holes, making them the most universal cups on the market.
