Bike fitting is the science and art of adjusting the geometry of a bike to maximize both the power output and comfort of the cyclist. The HSS Bike Fitting Service is the first hospital-based, in-house bike fitting program of its kind. We use the Apex Fit Bike from the UK – it’s one of the most advanced fit bikes available worldwide. It is a great tool for our experienced clinicians to determine what questions to ask, resulting in a better position and more precise fit.
Our program is led by Happy Freedman, internationally recognized bike fitting specialist and cycling coach with over 30 years of experience. With the resources at HSS, we go well beyond the scope of a traditional bike fit to accommodate your individual purpose and needs.
Your Performance Screen will be conducted by one of our Performance Specialists.
The Apex Fit Bike was developed in the UK. It’s one of the most advanced fit bikes worldwide. In addition to recording all of the cyclist’s positions during a fitting, we can measure energy output of each leg independently.
We can also use the Apex for physiology testing. This fit bike allows us to write our own software and to integrate bike fitting with medical technologies including surface EMG, force plates, 3D modeling, and more.
*Note: Not all tools and technology are necessary for all bike fits. The equipment required will be determined based on individual needs. Tools will be selected for specific applications to make the bike fit as optimal as possible.
Basic Bike Fitting
Advanced Bike Fitting
The standard bike fit takes 2 hours including a comprehensive Performance Screen. However, some fits for longer rides or triathlons can take 6 to 8 hours for optimal results. A full work up for elite athletes can take up to two to three days (you get a break, of course!).
Whenever possible we would like to see the bike you’re currently riding as well, particularly if you are planning on using that bike for your event. Even if we are doing a fit for a new bike, reviewing your current bike often reveals causes of current issues or complaints that can be remedied with the bike fitting process.
Bike fitting started in the 1970’s with the research and work done in cycling by bike builders like Ben Serotta in New York and researchers like Dr. Andy Pruitt in Colorado. In 1979, Ben Serotta paved the way for the development of modern bike fitting by inventing the size cycle, which allowed bike builders to replicate riding positions for a cyclist before actually building the bike. The size cycle allows the bike fitter to determine the geometry of the frame and a cyclist’s position on the bike before the purchase of a bicycle or creating a custom frame.
In the fall of 1985, Dr. Pruitt performed the first 3D motion capture bike fit. Their goals were to improve the cyclist’s position and mechanics while cycling, leading to better performance and fewer injuries. HSS’s first 3D motion capture bike fit took place in November 2000.
Today’s modern fit bikes do everything the original ones did and more, as they are connected to a computer that allows for a range of additional measurements. They record the cyclist’s positions and can measure energy output in watts. Combined with other tools such as lasers, motion capture video, force plates and more, today’s bike fit helps draw a much improved portrait of a rider’s measurements, which can then be translated into an improved riding position, through adjustments on the bike and off, including orthotics.
