Objective, Dynamic, Accurate data...
Every rider has unique biomechanics and therefore there are no generalizations that apply when truly fitting a rider to a bike.
Purchasing a new bike can be both a fun and exciting experience, but riding a bike that is not properly fit can cause frustration, pain, and ultimately may lead to putting the bike in storage where it’ll start collecting dust.

On the other hand, maybe you already own a bike and are experiencing some discomfort. A proper bike fit not only will provide you with the most economic means of expending energy, but will prevent that awful pain, such as in the knee, so common with riders who are trying to adapt their bodies to the bike they already have purchased.
We’d rather adapt a bike to the body you already have. There is a big difference between being sized for a bike and being fit for a bike. When it comes to the biomechanics of fitting a rider to his/her bike, little ‘tweaks’ can be very significant.
Retül is a state-of-the-art 3-D motion capture system designed
specifically for collecting the most accurate and realistic data for
bike fit specialists. By gathering data from key eight (8)
anatomical points in the cyclist’s riding position, fitters are able to
profile existing (before) and ideal (after) angles for their client’s
custom needs, which could be to gain more efficiency and performance,
more comfort or maybe to fit the customer around an injury.
The passive data collection devices still used by many fitters today,
such as a tape measure and plumb bob, are outdated and less accurate
because they are subject to human error. Fitting with the Retul system
however, provides sub-millimeter accurate dynamic data that is organized into an easy-to-read report for both the certified fitter as well as the cyclist.
Retül allows the bike fit expert to capture 100% objective data in a
dynamic state and evaluate multiple viewpoints (3-D) simultaneously
while the rider is pedaling. This system requires only a PC and +/- 80
square feet of space for line of sight requirements but can easily be
packed away for conserving space or taking the system with you.
Retül optimizes the biomechanics of the rider
while taking into consideration
