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.

Great Socks.
Color: (002) Black / Black / Halo Gray, Size: Large
These are awesome and have become my favorite socks to have for everyday wear. I have since bought the hightop version as well and there are just as equally great. They fit almost like compression socks. Color does fade a bit after repeated washing but not enough to make a big difference in appearance. They have lasted for a long time and still going. They have lots of cushion which makes it very comfortable to wear.

Great Socks
Color: (001) Black / Black / Castlerock, Size: Large
I keep ordering these over and over again. They fit well, and are soft and comfortable. My feet don't sweat like crazy while wearing them. The cupped heel makes them fit even better. They hold up to everything from everyday use to active lifestyles.

Good sock but thick
Color: (001) Black / Black / Castlerock, Size: Small
These Under Armour socks are high quality and definitely durable, with great cushioning and a solid fit that stays in place throughout the day. The material feels supportive and they hold up well after multiple washes without losing shape. My only minor downside is that they’re thicker than I expected. They feel more like a heavy-duty training sock, which is great for colder weather or intense workouts, but a bit bulky for everyday sneakers or warmer days. That said, the quality is excellent, and if you prefer a thicker, more cushioned sock, these are perfect. Just something to be aware of depending on how you plan to use them.
