Retul 3D Dynamic Fit

First measure, then improve

Retul: Bicycle Fitting for the Digital Age!
The Retul motion capture system was developed with professional racers and the best bike fitters in the world and now we bring this revolutionary fitting tool to you! With Retul's 3-dimensional motion capture technology, we can dial in your bike fit to millimeter tolerances. By allowing you to continuously pedal your bike in a trainer, the Retül system lets us see exactly what you're doing as you ride. Retül makes our bike fitting process faster and more precise so you can be riding at your best, sooner!

Why is a Retül Bike Fit Superior?
Every rider has unique biomechanics and therefore there are no generalizations that apply when truly fitting a rider to a bike. The Retül system provides millimeter accurate measurements of every moving angle of the body while riding at different workloads - thus providing the fit specialist with the information needed to fit you to the bike and realistically mimic your ride on the road. Retül helps the fitter optimize the biomechanics of the rider while taking each rider's goals into consideration.

We place eight markers atop anatomical landmarks (see illustration), along one side of your body that will be used to analyze your full body movements while riding your bike. The small Retül wiring harness is then attached to these markers and information about your riding is sent to the computer. The harness uses tiny LED lights that flash 42 times per second to send data to the sensor. The Retül software then processes all of that data in seconds, synchronizing the eight data points and tracking them across longitudinal, vertical and horizontal planes.

 

The fitter gains a wealth of information from the system. For instance, we can see all of the different knee angles throughout your pedal stroke. And the sensor is able to capture tiny lateral movements, such as knee wobble, that tells us how your body is moving in three dimensions. We repeat this process on the other side of your body to find any asymmetries between sides.

Clearly, the same accuracy and volume of data cannot be achieved by using a measuring tape to measure the rider in a static position. Even video-based systems, while impressive looking, cannot capture measurements in three dimensions, all while you are riding!

After capturing this information from Retul, the fitter is able to objectively analyze the data from the sample and evaluate the need for a position change. Once the changes are made, the process is repeated to verify effectiveness. This new data then becomes part of the final report, in addition to bike geometry measurements.

Once we have your final position dialed in, Retül allows us to keep that information in a convenient 3D digital record so we know exactly how to set up any bikes you may purchase in the future. Just as important, with Retül, we can quickly and easily compare your past and present bike fits as both your body and your cycling needs change over time.

Already chosen by numerous pro cycling teams and pro athletes such as Ironman World Champion, Craig Alexander, the Retül Bike Fitting System is available to you at ARB.
