What Our Gearhead(R) Experts Are Saying: "I use these to level out BTA bottles on aggressive aero setups. The 5deg increments make it easy to dial in the angle so fluid sits properly and refills are smoother. Lightweight, simple, and a smart add-on for anyone running an HSF system."When we're locked into aero and focused on steady power, even small cockpit details matter. The HSF BTA Wedges from Profile Design let us fine-tune our between-the-arms hydration setup, ensuring bottles sit level and ready for quick, efficient refills. Constructed from injected nylon reinforced with glass fiber, these wedges are strong, lightweight, and built for race-day reliability. Each kit includes three 5deg wedges, allowing up to 15deg of total tilt adjustment to match aggressive aero positions. Designed to pair seamlessly with the HSF Aero HC 800 or any BTA mount using a standard cage interface, they help maximize fluid carrying efficiency without compromising fit or aerodynamics.
