Signature Open Back Arm Cups

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.  For enhanced cockpit compatibility, consider adding Wingspan Extenders to your cart. If you need hardware for Speed Concept compatibility, add it to your cart as well. FEATURES: At 365 grams per set, these cups deliver minimal weight with maximum comfort. Ergonomic Support: Increases arm wrap and surface area for a more comfortable ride, ideal for extended use. Extended Adjustment Range: Features multiple mounting points and slotted bolt holes to accommodate various setups. Textured Neoprene Pads: Provides superior grip and cushioning for enhanced comfort and stability. SPECS: Compatibility: Scoops mount using two fore/aft bolts into matching threaded bosses on your arm-pad bracket/aerobar. Check that your bracket’s hole pattern aligns; both bolts must be used for a safe, stable install. Non-standard patterns may require Wingspan Extenders. Fits most aerobars on the market, including Alpha One. Comes with M5 and M6 bolts for easy installation. The Open Back SL Carbon Arm Cups are not recommended for use on the Trek Speed Concept Gen 3 (2022+) due to their narrower hole pattern. Other Scoops variants are compatible with the appropriate hardware kit.
