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.

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!
How to pick your BTA System
Measure your arm rest bolt mounting areas total width and length to determine the correct baseplate. For example here the correct size is about 160-205mm.
Then use your phones angle measurement app to determine correct angle of BTA.
AND don't worry, we'll personally help you pick the correct BTA
Wow! The BTA mount and arm rests are top notch quality for such a great price. Not to mention how easy the complete system was to put together.
I highly recommend this product to anyone looking for a quality upgrade to their hydration and TT position.
Kev’s customer service was excellent throughout the entire process which was the cherry on top!
Everything worked out. Feeling great about my BTA hydration system. Worked perfectly for my first race.
A very professional approach. A custom solution that fits my handlebars perfectly. Fluid intake is now easier at triathlon races than ever before.
Excellent product! It's absolutely worth the price.
Great quality, very easy to install. Nothing to complain about!
Perfect support and great product! The system had to be modified a bit to make it fit the DTU regulations, however that was not an issue at all as the team supported me from the beginning on, and made the supercar fit within the regulations! Great customer support and great product. Highly recommended!

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.
