Profile Design HSA Riser 90mm Kit (2x 45mm Spacers)
Category: Spare Parts
Subcategory: Headsets
Elevate your performance and refine your aerodynamic profile with the Profile Design HSA Riser Kit. Specifically engineered for dedicated triathletes and time-trial cyclists, this essential upgrade allows for precise vertical adjustment of your between-the-arms (BTA) aerobar hydration system. In a sport where every watt and every second is critical, optimizing the position of your hydration bottle can lead to significant gains in aerodynamic efficiency and on-bike comfort. This kit is the key to unlocking that potential, enabling you to create a seamless, wind-cheating silhouette by positioning your bottle perfectly in line with your arms and head.
The primary benefit of the HSA Riser system lies in its exceptional modularity and its direct impact on drag reduction. By raising your aerobar-mounted bottle cage, you can effectively fill the gap between your arms, smoothing airflow and minimizing turbulence. This not only makes you faster but also enhances stability. The kit provides a total of 90mm in potential height adjustment, achieved through two individual 45mm riser units. Use a single riser for a 45mm lift or stack both for the maximum 90mm elevation, giving you the flexibility to dial in the exact height that complements your unique riding position and aerodynamic goals. These versatile Spacers are the ultimate tool for personalizing your race-day setup.
Achieving the perfect bottle placement is about more than just height; it´s also about angle and accessibility. The Profile Design HSA Riser works seamlessly within the Profile Design ecosystem. Pairing the riser with our BTA wedges will allow riders to fine-tune the placement of their bottles to achieve the best accessibility, ensuring you can hydrate quickly and confidently without breaking your aero tuck. The system is designed for broad compatibility with any standard 65mm spaced BTA mount, making it a versatile addition to a wide range of triathlon and TT bikes. Its durable, lightweight construction ensures that you add function and performance without a weight penalty.
Key Features:
* Aerodynamic Optimization: Raises your BTA hydration system to reduce aerodynamic drag by smoothing airflow between the arms.
* Modular Height Adjustment: The HSA Riser works with our aerobar mounted brackets to raise the bottle by 45mm. The risers can be stacked for a total height of 90mm, offering customized positioning.
* Enhanced Accessibility: Lifts the bottle to a more natural and easy-to-reach position, facilitating faster and safer hydration during competition.
* Precision Tuning: Designed to be used in conjunction with Profile Design BTA wedges for micro-adjustments to the bottle´s angle.
* Universal Mounting Standard: Compatible with any 65mm spaced BTA mount, ensuring a wide range of application.
* Lightweight Performance: A robust and lightweight construction adds minimal weight to your setup while providing a secure and stable platform.
