The Aerodynamics:
The oncoming airflow gets redirected by the EZ BTA Bullet to follow a smoother path, reducing drag inducing vortices that it might experience when it hits the flat wall of a normal bottle. These airflow contours help show you how the air will travel more smoothly when you use the EZ BTA Bullet. Even when an athletes arms are in front of the EZ BTA Bullet, the more turbulent air will still benefit from having a smoother surface to guide its travel, reducing the separation and therefore drag at the bottles flat edges when there isn't an EZ BTA Bullet.
Tested and Approved by the World Champ
Casper Stornes tests faster with the EZ BTA Bullet, even with a highly optimised set up like his! His TT plate on the front reduces drag saving of the EZ BTA Bullet and he still saved 3.5 watts!
Watt Savings at Different Speeds
At 40km/h it is estimated that you can save 3 Watts, and this was with an already highly optimised athlete, meaning for age-groupers we estimate it will be even more! This data indicates that the horizontal setup is more optimised than the placing your BTA at a diagnol with the EZ BTA Bullet, but both are far more aero than without the BTA Bullet.

EZ BTA Bullet: Aero Gains + Smart Storage
The EZ BTA Bullet delivers free speed while providing a clean, secure space to store a spare gel right between your arms, right where it belongs.
Wind Tunnel Proven
Tested on 1st December 2025 at the Silverstone Sports Engineering Hub Wind Tunnel with World Champion Casper Stornes, the EZ BTA Bullet delivered:
-
+3.5 Watts gain on Casper’s elite aero cockpit system
Further testing showed even greater gains when fitted to standard cockpits, meaning:
-
Most age group athletes can expect even bigger improvements
