Product Overview
This complete between‑the‑arms (BTA) hydration system takes front‑end fueling in triathlon and time‑trial racing to the next level. It‘s not just a quick bottle holder – its core purpose is to place your bottles precisely where aerodynamic drag is minimized.
The system combines a precision BTA riser, lightweight bottle cages, and dedicated bottles to offer unmatched adjustability. From raising and lowering to tilting and fine‑tuning fore/aft position, you get full control over bottle placement – adapting to your body, riding position, and race distance.
Key Features
Precise control & stepless adjustment – The BTA riser offers a height range of 100–157mm and ±25° tilt. Fine‑tune bottle position for the best aero benefit without sacrificing drinking comfort
Designed for tight cockpits – Ideal for riders with narrow armrest spacing. The modular design allows quick switching between single‑bottle and dual‑bottle configurations for different race distances or training needs
Wide compatibility – Uses standard 63mm bottle cage spacing, integrating seamlessly with most bottle cages and aero handlebar mounting systems
Aerodynamic optimisation – Positions bottles between your arms to reduce frontal area. Wind‑tunnel data shows an optimised BTA setup can save 8+ watts
Aerospace‑grade materials – The BTA riser is CNC‑machined from T6‑6061 aluminium with a hard‑anodised finish – lightweight, rigid, and durable enough for the demands of long‑course triathlon
