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.
