What Is BikeFitting
A professional bike fit is the evaluation of a rider’s physical condition,abilities and needs then adjusting the bike to meet those requirements.
Bike fitting is finding the personal position that suits the needs of the rider at the time of the fit.
Any rider who spends a significant amount of time on the bike will benefit from a professional bike fit.
Brief History of bike fitting
Ever since the days of custom hand-made frames by Cino Cinelli there have been formulas to compute frame size and saddle height. Mostly it involved some sort of inseam or leg length measurement times by a magic number to get to a frame size. The rest of the bike set up was usually set up to mimic how the pros at that time rode. All the bikes of that era seemed to have narrow slammed handlebars and high seats.
It was LeMond’s formula of 0.886 times your inseam measurement that brought bike fitting into mainstream discussion. At the time LeMond had just won the Tour de France and everyone wanted to ride like him. If it worked for Greg LeMond then its good enough for me. What everyone didn’t know at the time was that LeMond has longer than average femurs so what worked for him probably didn’t work for everyone.
Another rule of thumb that I routinely still hear today is that your heel should just clear the pedal at the bottom of the pedal stroke while remaining in the seated position. The end result being that as you move your foot to the cycling position you will have a slight bend while pedaling.
These theories and formulas have not changed much over the years with a general consensus being that the knee had to be in slight flexion and your elbows slightly bent.
It wasn’t until the 80’s and 90’s that the schools of thought from Fit Kit, BikeFit and Serotta started to show repeatable and measurable results.
Through the 90’s and early 00’s bike fitting was dominated by static bike fitting techniques and the world of plumb bobs and goniometers.
These theories are fundamentally true and are correct foundations for any good bike fit, but bike fitting was truly revolutionized when 3D software of DartFish and Retul became mainstream. Simplified, 3D bikefitting digitizes and crunches thousands of static bike fits at once and analyzes them through the same fundamental fitting process. It allows the rider to be analyzed in a truly dynamic fashion without any hindrance of starting and stopping to take measurements. It is a much more natural way of analysis.
That being said there are many factors that affect the rider’s final position.
Active ankling, hamstring and quadricep flexibility, saddle tilt, handlebar width and drop, cleat fore/aft position, style of riding, event type all affect the rider’s most comfortable position.
The best way to determine your personal position is with the help of a professional trained bike fitter.
