The FORMA makes it easy to train and race in your ideal aero position. This body position device mounts on the cockpit of the bike and connects with Garmin bike computers. Infra-red lasers measure riders' head and chest distance and the deviation from their reference (ideal) aero position is shown in real-time via an app installed in the bike computer. Post-ride data can be viewed via FIT file.
