If you're looking to make your triathlon bike faster, more practical and race-ready, investing in a quality Triathlon BTA System is one of the smartest upgrades you can make.

A Triathlon Hydration System positioned between your arms keeps fluids within easy reach while helping maintain an aerodynamic riding position. But not all BTA systems are created equal. The ability to adjust bottle height, tilt and positioning can make a significant difference to both comfort and performance.

What Is a Triathlon BTA System?

A Triathlon BTA System (Between-The-Arms System) mounts your bottles directly between your aero extensions. This keeps hydration within easy reach while maintaining your aerodynamic position, reducing unnecessary movement during training and racing.

Unlike traditional frame-mounted bottles, a well-designed BTA setup allows you to drink without sitting up, helping you stay comfortable and efficient throughout long rides and races.

Why Adjustability Matters

Every rider's cockpit is different.

Aerobar width, extension angle, elbow pad position and riding posture all vary, meaning a fixed bottle mount rarely provides the ideal fit.

That's where the Ultimate Adjustable BTA System stands apart.

Rather than forcing you to adapt to the system, it allows you to fine-tune your Triathlon Hydration setup by adjusting:

  • ✓ Bottle height
  • ✓ Bottle tilt
  • ✓ Forearm clearance
  • ✓ Single or double bottle configuration

Whether you're racing an Ironman, 70.3 or Olympic distance event, these adjustments help create a more comfortable and efficient cockpit.

Adjustable Triathlon Hydration System

Designed For Modern Triathlon Cockpits

Many modern triathlon bikes feature narrow aerobar positions, leaving limited space for traditional bottle mounts.

The Ultimate Adjustable BTA System has been designed specifically for these tighter setups, giving athletes the flexibility to position bottles exactly where they work best.

The system uses standard bottle cage spacing, making it compatible with almost every bottle cage and the majority of BTA mounting systems.

If required, the optional Universal BTA Mount also makes installation possible on bikes without an existing BTA mount.

Single Or Double Bottle?

One of the biggest advantages of this Triathlon BTA System is its flexibility.

For shorter races or lighter training sessions, you can run a single bottle setup.

For long-course racing, simply switch to a double bottle configuration to carry additional hydration without compromising accessibility.

This versatility means one system can adapt to almost any race distance or training session.

Who Is This Triathlon Hydration System For?

The Ultimate Adjustable BTA System is ideal for:

  • Triathletes racing Sprint, Olympic, 70.3 or Ironman events
  • Time Trial riders looking for an adjustable hydration solution
  • Athletes with narrow aero cockpits
  • Cyclists wanting a cleaner, more ergonomic cockpit
  • Anyone looking for a premium Triathlon Hydration system that can evolve with their bike fit

Final Thoughts

A high-quality Triathlon BTA System isn't simply about carrying water. It's about creating a cockpit that works with your riding position rather than against it.

With adjustable height, adjustable tilt, support for single or double bottle setups and compatibility with standard bottle cages, the Ultimate Adjustable BTA System offers one of the most versatile Triathlon Hydration solutions available.
