Frame Finder is a web app that graphically overlays the fit dimensions of real-life bikes on top of a rider’s personal fit coordinates. If a bike’s seatpost can move up and down 10 centimeters and back and forth 4 centimeters, Frame Finder creates a rectangle that is 10 x 4 centimeters to encompass every potential saddle position. It does the same for stems, aerobars and saddles to depict every possible fit configuration.
