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.

Ultra-Lightweight Carbon Design: At 275 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.

Maximum Comfort, Minimal Materials

Scoops Arm Cups dramatically increase the reach, arm wrap, and surface area of the cup compared to anything on the market. At the same time, they also increase adjustment range with additional mounting points, slotted bolt holes, and superior textured neoprene pad material. These are perhaps the most universal cups ever made, allowing virtually any ride to get a major ergonomic upgrade. Of course, we think they work particularly well with Alpha One.

Game Changing Minimal Design

Scoops Arm Cups give you all the support and ergonometry you could ever dream up. The slimmed-down design packs a serious punch. Sacrificing no compatibility or functionality, this redesigned minimal-materials version proves to be the most efficient and effective line of Scoops we've ever designed.

Plug and Play

Scoops work with almost any bar on the market, and come with everything you need to fit them. A variety of M5 and M6 bolts are included for install. Just unbox, bolt on, and go!
