Why Retül Can Help You
Buying a bike is about much more than picking the one that pleases your aesthetic sensibilities the most, as it's the fit that will largely determine how much enjoyment you will gain from your bicycle. So it's important to get the right size in the first place.
That's the easy step, however. There are many parts to setting the bicycle up that contribute to the fit, and it's quite easy to see how many people struggle to set their bike up to gain the most performance and provide comfort. With that in mind, we move onto Retul, the latest in an increasing range of bike fitting tools.
Retul is a state-of-the-art motion capture system that collects data from 7 anatomical points in a cyclist's riding position. The system provides millimeter-accurate data organised into an easy-to-read report. It's dynamic, collects data while the rider is pedaling on the bike and requires just a computer and enough space for the system to operate.
The fit begins with an interview to gain a profile of the type of riding you take part in, your cycling history and your future plans. You might be planning an attack on the local road races or equally just want to get around Taupo quicker than last year. The process then moves onto measuring your body, with some exercises to realise your range of flexibility.
Retül captures the rider's position relative to his pedaling motion, and therefore creates the most realistic replication of the actual pedal stroke and body position when out on the road and trails. Cleat positioning is often misunderstood but vitally important component of the overall bike fit. Your bike is placed upon a static trainer and after a short duration of pedaling, your position is recorded by the sensors and the data translated by the computer to provide an A4 sheet packed with numbers. This information can now be used to adjust your current bike or be used to help design a new custom bike. For the former it may be a case of adjusting your stem choice, handlebar widths, crank length, fitting cleat wedges, shims or seatpost layback.
Exceed Bike Fit have a large variety of specialized fitting tools at their disposal, including special sizing stems for adjusting handlebar position, size cycle, seat-posts with varying degrees of layback, saddles of different shapes and sizes, handlebars and aero bars of different widths and configurations, trainers, tools for tracking joint movement, and solutions to issues..
Each Fit appointment is different as clients have varying needs. In fitting one brings to bear whatever tools are necessary to achieve the goals, whether it is to set up your existing equipment, fit your second bike, analyse your pedal stroke, or help you with the selection of your new dream bike. A Comprehensive Fitting Analysis generally takes 2 hours, and is available by appointment only.
How does it work?
The system uses infra-red LEDs (light emitting diodes) that get placed on the body in key movement locations. The active system flashes each LED discreetly as the infrared light travels from the LEDs on the body points to the sensor on the tripod. The sensor then triangulates the position of the LED in 3D space. The system can track these points to within a millimeter of true position.
It's fast too. The system flashes an LED every 2.1 milliseconds. That's 476 times per second or 476Hertz. The system takes a full set of body measurements every 34 milliseconds. That's 29 full sets of body data per second.
Normally you would have had to travel to the overseas for a Retul fitting. However, Exceed Bike Fit has the only NZ Retul. A complete Retul body exam and bike fit will set you back $350.
