SRF Measurments

Once the initial bike setup is completed, the rider takes their place on the bike and the SRF setup is cross-checked against an evaluation of real rider positioning using a digital inclinometer to establish accurate measurements of angles of rider torso, leg extension and arm positioning. Measurement are captured on the SRF application.

Sizing Guide



The SRF software returns a set of recommendations for final setup in the event that the initial setup differs from the intended positioning delivered in the first step of bike setup. Final adjustments are made and the bike is ready to ride.
