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."
