Level I: Using the adjustable Retül SL machine, test the sizes and geometries of up to 4 bikes using video analysis. Get a compete report with your measurements and final recommendation !

Level II: Adding the 3D Retül 8 point pedaling analysis, much like the tech used in video games, allows us to analyse every possible angle and measurement of your position in real time ! This is a great way to see and track your pedaling style, knee movement, foot angle and movement, hip rotation and so much more, and how different bike sizes and geometires can affect these results. Test up to 6 bikes !

Level III: Get into the details with unlimited testing of bike geometries, custom geometries, crank arm lengths, stem lengths, bar widths, saddle models, cleat positions and so much more. Included is a follow up so come back with your bike when it has arrived to fine tune it. This is the option to find your ultimate unrestricted perfect position with every component custom, all from A-Z and beyond !
