What Our Gearhead(R) Experts Are Saying: "This is a super clean way to add a BTA bottle to a clip-on setup. It's lightweight, simple to install, and works especially well with ASC extensions. I like that you can flip it to fine-tune bottle position without adding bulk."When we're dialing in race-day hydration, simplicity and aerodynamics go hand in hand. The HSA Mini BTA Mount from Profile Design offers a sleek, low-profile way to position a bottle cage between our aerobars-keeping fluids within reach without cluttering the cockpit. Constructed from injected nylon reinforced with glass fiber, this mount balances strength and minimal weight at just 16. 5 grams per pair. Designed for 22. 2mm round extensions with 100mm center-to-center spacing, it integrates cleanly with shaped extensions like the ASC series. The dual-bracket design mounts in front of and behind the aerobar brackets, securing a standard cycling cage (sold separately). It can also be reversed and flipped for fine-tuned bottle placement, making it a versatile solution for triathlon and time trial setups.
