User case studies

How to use the system

1. Case Study

Sam Barley - Fitted by Sam

Helping Kristian Blummenfelt optimise his aero position in preparation for IM World Championships.

"We used the saddle roll and positional stability data to confirm that small aero gains weren't compromising rider efficiency. The real-time feedback helped us hold both aero and biomechanical form during longer TT efforts."

2. Case Study

Sam Thompson - Podium Addict Performance Coaching

Reviewing the impact of changing skin & tri suits.

"What I love about the saddle metrics is how clearly it shows when a position is sustainable versus when it just looks good on video. This data gives me a new level of confidence in the changes I recommend during fits."

3. Case Study

Steve Loraine - Steve Loraine Coaching

Aiding an athlete with optimising position to reduce aggrevation of a shoulder injury.

"For me, the game-changer was being able to track how saddle movement patterns shift under fatigue during real rides-not just in the fit studio. It's helped me guide athletes toward more efficient, race-day-ready setups."

Frequently asked questions

What cyclecomputers are compatible with Body Rocket?
Arrow

Our goal is to make aerodynamics accessible to as many people as possible so we’re certainly not trying to limit which computers our system works with! Right now there’s no standard for communicating aero data to a cycle computer so we use Garmin’s Connect IQ system to display aero data on all Garmin devices

Will I have to pay for the dashboards, or BRIAN?
Arrow

The dashboards, as we’re showing them, come free with the product. BRIAN, and future dashboard features will be included for 3 years with all pre-order products.

How accurate is the Body Rocket System?
Arrow

Body Rocket is the only on-bike aero device to ever validate their aerodynamic drag readings in the wind tunnel, showing accuracy to within a +-2.5% error. In field testing scenarios, where it’s possible to limit variables, we regularly see results repeat to 1% error or better.

Do you ship internationally?
Arrow

Yes, we offer international shipping. Body Rocket is available to customers around the world including the US, U.K., Europe and more. To find out more about our shipping rates, check out our shipping page.
