The TriRig Signature Closed Back Arm Cups are a breakthrough in aero comfort. Built from our ultra-light, durable ThermoPlast™ material, these arm cups offer the perfect blend of strength, lightweight performance, and affordability, making them one of the most competitively priced upgrades for serious triathletes and time-trial cyclists.

The Closed Back Scoops not only function like standard arm cups, but they also provide additional support at the back, wrapping behind the elbow. This design is ideal for riders using high-hands or upward-tilt positions, keeping you locked into your aero position while allowing your upper body to relax. For optimal grip and comfort, each set of Closed Back Arm Cups comes with our signature textured neoprene pads pre-installed.

The Signature Closed Back Arm Cups offer one of the most significant comfort upgrades you can make to your triathlon or TT bike. When you’re comfortable, you stay in your aero position longer, which directly translates into faster times. 

FEATURES:

  • Enhanced Support: The closed-back design offers additional elbow support, ideal for high-hand or upward-tilt aero positions, keeping you locked in for maximum comfort.
  • Maximum Comfort and Grip: The included textured neoprene pads offer excellent grip and cushion, ensuring a comfortable ride, even over long distances.
  • Strong and Lightweight: Crafted from our high-performance ThermoPlast™ material, these cups are both ultra-lightweight and extremely durable.
  • Increased Adjustment Range: Features additional mounting holes and slotted bolt holes for a wider range of positioning options.
  • Compatibility:
    • Fits most aerobars on the market.
    • Comes with all necessary hardware, including M5 and M6 bolts.
