The Supercar BTA is a simple, fast and easy-to-use between-the-arms hydration system.

A BTA setup is one of the fastest ways to carry hydration on a triathlon bike. It keeps your bottle easy to reach, encourages you to drink more consistently, and can even be faster than riding without a bottle at all.

2 Bottle Cages (+35 eur)
Computer Mount (+8 eur)
Rocketcone (+8 eur)

Locked-in Hydration

The Supercar BTA puts your hydration in the most optimized possible position - between your arms. Bottles are easier to reach and drink from, easier to change and the system fills in the gap between your arms, thus improving your aerodynamic gainzzz a whole lot.

Works With 99% Of Setups

The custom made baseplate platform accommodates a wide range of extension widths, bottle cages and riding positions without locking you into a proprietary ecosystem. If we haven't made an option which'll fit your system, we'll make it for no extra cost!

Carbon Composite Build

  • Works Universally

    No special bottles, special mounts and special accessories. The Supercar BTA works with standard components, so you're free to build a setup that actually suits your bike.

  • Custom for You

    Not every cockpit looks the same, so why should every hydration system? Send us your measurements and we'll make it custom for no extra charge

  • Ride Confidently

    We use these products ourselves and stand behind every one we make. If something goes wrong, you'll be speaking directly with the people who designed and built it.

The Faster Position

Everyone knows hydration matters. Hydration setup matters too.


By filling the space between your arms, it creates a cleaner front profile while keeping hydration within easy reach.

Free gainzz baby!

No Proprietary Nonsense

The Supercar BTA works with standard bottle cages and standard 500ml-750ml bottles, giving you the freedom to build a setup that works for you. We do recommend Elite Bottle cages tho!

Simplicity FTW

Most hydration systems are designed around averages.

We design custom around you. Detailed measurement guides allow us to adapt the system to a huge range of extension widths, positions and cockpit layouts.

Level the Playing Field

Cycling has a habit of taking itself too seriously. In the chase for marginal gains, costs go up and the everyday rider gets pushed out.

We don’t hate performance - we love it, but there’s a time and place for elite-level gear. There should also be space for riders who want competitive kit without the barrier of entry.

We simplify design, production, and setup to make performance more accessible.

More access means more riders. And that’s better for the sport.
