The TriRig Open Back Carbon Arm Cups are designed to take your aero comfort to the next level. Building on the success of our Mini Open Back Arm Cups, these carbon versions elevate every aspect of performance and comfort. With a total length of over 200mm, the Open Back Carbon Arm Cups provide support and stability for riders seeking the perfect balance of aerodynamics and comfort.

Featuring the same textured neoprene pad that has been so popular with our original arm cups, these carbon scoops ensure an optimal grip and cushion, keeping you comfortable even during long-distance rides. Each set comes with pads pre-installed for an easy and seamless setup.

The Open Back Carbon Arm Cups offer one of the most substantial comfort upgrades available for triathlon bikes. The more comfortable you are, the longer you can stay in your aero position, which means faster ride times. These cups are a game-changing upgrade for anyone looking to improve both comfort and speed on the bike.

For enhanced cockpit compatibility, add Wingspan Extenders to your cart. Need hardware for Speed Concept compatibility? Add it to your cart for seamless installation.

FEATURES:

  • At 402 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/Alpha Prime.
  • 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.

Soft and comfortable
Size: Small, Color: 5 Pack - Modal Blue/Red/Grey
My son love that these are longer on his tights than other brands that ride up. No more picking wedgies during sports! Very happy with them as a mama. My son says they are soft and comfortable and asked for me to order more!

Soft and super comfortable
Size: 4-5T, Color: 10 Pack - Covered Waist, Size: 4-5T, Color: 10 Pack - Covered Waist
As my youngest son is growing rapidly, I decided it was time to surprise him with a new set of toddler boys boxer briefs. I loved that this pack came with a set of 10, and it had 7 pairs Monday through Sunday and 3 solid colored ones. It's been so much fun to teach him the spelling of the days and to help recognize the letters. As well as letting him pick his favorite design or color. He is 4 1/2 years old and right in the middle of 4t and 5t clothes. This was true to it's size and fit him perfectly. I love that these are tagless, and the tag print is designed inside. These are super soft, stretchy, and comfortable. Perfect for a preschooler! He is comfortable in these, to play various of sports, wrestling with his big brothers and running around the playground. I love the soft waistband that doesn't put pressure on his waste and wicks moisture, as well as 100% cotton!! Don't forget to tumble dry low in the dryer, or in my case, I just let them air dry. They don't shrink after several washes and seem to last a while! I couldn't be happier with my purchase. Great job to Fruit of the Loom for designing these for my toddler!

Excellent quality
Size: Large, Color: 10 Pack - Breathable Micro Mesh
These boxer briefs are excellent quality and very comfortable for my son. The fabric is soft and breathable, and they don’t irritate his skin. They’ve held up well after many washes without stretching out or fading. The waistband stays in place, and the fit is true to size. Great value for the price — I’ll definitely be repurchasing
