Mini Closed Back Signature Arm Cups

Mini Closed Back Signature Arm Cups: Maximum Comfort for Your Aero Position

The Mini Closed Back Arm Cups provide comfort and support for your triathlon or TT bike. These arm cups take the proven design of our Mini Open Back Arm Cups and enhance it with our patented closed-back design, offering the most substantial arm wrap and surface area of any arm cup on the market. With a length of 127mm, these cups ensure a stable, comfortable fit, keeping you in the aero position longer for faster rides.

Featuring the same textured neoprene pad as the Mini Open Back Arm Cups, the Mini Closed Back Arm Cups deliver an exceptional combination of grip and cushion, making them one of the best comfort upgrades available for triathlon bikes.

If you require Speed Concept wingspan, add it to your cart for easy installation.

TriRig designs innovative, aerodynamic products built with elite athletes and proven through real-world performance. With a relentless focus on progress, problem-solving, and minimal design, every product helps athletes push limits and achieve their personal best.

• 226 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.

• ⚙️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.
• 🔧 Need help with the install? See our install guide.
