OFFERS RETUL 3-D BIKE FITTING TECHNOLOGY TO CYCLISTS AND TRIATHLETES
I use the Retul 3-D motion capture and analysis technology system for helping my cycling and triathlon clients to provide fast and accurate data collection to aid in bike fitting and avoiding injury. The Retul system uses infra-red LEDs (light emitting diodes) to be placed on the body in specific skeletal locations. Currently the US Triathlon team, Garmin/Slipstream Chipoltle Pro Cycling Team and pro athletes such as Ironman World Champion, Craig Alexander are benefitting from using this technology.
The Retul system collects data and allows me to more effectively analyze the rider to determine accurate saddle and handle bar positions, as well as the position of their feet on the pedals and their wind resistance. These data provides me instant and valuable information to optimize bike fitting, helping to avoid injury during training as well as squeeze out better racing times.
Prior to using the Retul software, all my clients are interviewed and their own “fit” data is stored in client specific files, which can be accessed at any time to compare previous fittings with new data. This “active” system differs from passive systems (similar to those used for motion capture for films and video. Note, I continue to use video analysis for basic bike fits and showing clients how they look on the bike for educational purposes.) in that the tripod mounted LED sensor is tracking the light directly from the source (the LED diodes). This avoids problems of false data encountered by passive systems that use reflective markers which can be confused by additional reflective objects outside the system such as shoes, clothes, or the bike itself.
The system flashes an LED every 2.1 milliseconds (476 times per second) and takes a full set of body measurements every 34 milliseconds, making 29 full sets of body data per second. The sample sizes or duration from the LEDs can be set for 5 seconds to 5 minutes, depending on the requirements of the rider. The Retul software then processes all of that data in seconds, synchronizing the eight data points tracking them across longitudinal, vertical and horizontal planes. After capturing this information, I am able to objectively analyze the data from the sample and evaluate the need for 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 post-fit bike and equipment measurements.
Already chosen by the Garmin/Slipstream Chipoltle Pro Cycling Team and pro athletes such as Ironman World Champion, Craig Alexander; the Retul Bike Fitting System is available for you at Velo Smart Coaching.

The Retül system is a state-of-the-art motion capture system designed specifically for collecting the most accurate and realistic cycling specific data in three dimensions. By gathering data from eight key anatomical points in your riding position, I am able to profile existing (before) and ideal (after) angles to meet your specific needs.
The results...more efficiency, power output, performance and comfort.
Why is a Retul 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 Retul system provides sub-millimeter accurate measurements of every moving angle of the body while riding at different workloads – thus providing me with the information needed to fit you to the bike and realistically mimic your ride on the road.
Retül optimizes the biomechanics of the rider while taking your goals into consideration:
• Performance
• Comfort
• Injury Prevention
If you are riding a bike that is not properly fit it can cause frustration, discomfort and pain. Visit Velo Smart Coaching and RETUL (retool) for your positioning and bike fit.
