TriRig Signature Arm Cups

The TriRig Signature Arm Cups are crafted for triathletes seeking unparalleled comfort and performance in the aero position. Available in both Open Back and Closed Back versions, these arm cups are designed with advanced materials and innovative features to enhance your ride, reduce fatigue, and help you maintain an optimal aerodynamic position for longer periods.

Signature Open Back Arm Cups

The Signature Open Back Arm Cups combine strength, durability, and comfort at an affordable price point. Made from TriRig's ultra-light ThermoPlast™ material, these cups provide exceptional performance without the added weight. The open back design ensures a more traditional fit and a larger range of motion, while the textured neoprene pads deliver the perfect balance of grip and cushioning, keeping you comfortable during long rides in the aero position.

One of the standout features of the Open Back Arm Cups is their increased adjustability. With multiple mounting points and slotted bolt holes, these cups offer a versatile fit for a wide range of riders and setups, making them one of the most universally compatible options on the market.

Signature Closed Back Arm Cups

The Signature Closed Back Arm Cups take comfort to the next level with their innovative design. Also made from the same durable ThermoPlast™ material, the Closed Back cups feature a unique back scoop that wraps behind the elbow. This design provides added support for riders who use a high-hands or upward-tilt aero position, helping you stay locked into your aero position while reducing tension in your upper body.

With their sleek and supportive closed-back design, these cups offer an ideal solution for athletes seeking greater stability and comfort. Like the Open Back version, they come with textured neoprene pads pre-installed, offering superior grip and cushioning for maximum comfort during long rides.

Key Differences

• Open Back Arm Cups: Ideal for riders looking for a traditional, open-backed design with more freedom of movement. They offer increased adjustability and comfort, thanks to the textured neoprene pads and versatile mounting options.
• Closed Back Arm Cups: Designed for riders in high-hands or upward-tilt positions, providing additional elbow support and enhanced comfort. The closed back design locks you into the aero position, helping to relax your upper body and maintain optimal form.

Both versions are crafted with the same ultra-durable ThermoPlast™ material, offering strength, lightweight performance, and unbeatable value. Whether you choose the Signature Open Back or Closed Back Arm Cups, you’ll experience one of the most significant comfort upgrades for your triathlon or time-trial bike, helping you ride faster and stay more comfortable in your aero position for longer.
