TriRig Signature Open Back Arm Cups

The TriRig Signature Arm Cups are designed to improve comfort, support, and adjustability for triathlon and time trial aero positions. Constructed from TriRig’s lightweight and durable ThermoPlast material, the open-back design provides increased arm wrap and surface area to help riders stay comfortable in the aero position for longer.

Textured neoprene pads provide a balance of cushioning and grip, while multiple mounting points and slotted bolt holes offer a wide adjustment range for different cockpit setups. Compatible with most aerobars, including TriRig Alpha One, the Signature Arm Cups provide a practical upgrade for riders looking to refine fit, stability, and long-distance aero comfort.
