The F.I.S.T. Method for fitting triathletes to their bikes

Sport is full of "systems." One might ask if all these systems are necessary, since bike riders rode, swimmers swam, and runners ran (quite well, in fact), before any of today's systems. Why do tri bike owners need a bike fit system?

In point of fact, they don't. The worth of any of these systems is directly proportional to their abilities to transfer functionality that is already well-established in sport. A system for teaching a proper golf swing, or tennis serve, results in a student's ability to play tennis or golf in a way quite similar to those who are especially adept at these sports.



The end result of a FIST fit is a position easily recognizable. Any fan of baseball, tennis, basketball, bowling, or any sport grows to know what good technique looks like. Any triathlete who follows the sport knows what a good tri bike position looks like. You don't need to be a pro to know how a pro rides.
