What is Retül?
The retul system is the only motion-capture technology on the market that allows bike fitters to fit the cyclist dynamically while using three dimensional-angles to analyse the ride's biomechanics. The Retul software captures thousands of data point from cycling specific movements, and inputs real-time data into a personalized customer fit report.

Retul has become the most advanced bicycle fitting system available today. The old way of measuring a fitter involved tape measures and plumb bobs. These type of tools do not allow for accurate measurements while the rider is pedaling. The Retul system reads the body in 3D, while the body is actually in motion. Retul is taking the guesswork out of measuring, while providing the bike rider with an accurate data set available in bike fitting. By using the Retul System, this will allow the rider to have a "true fit" to the bike allowing for maximum results while avoiding injury and discomfort.

What are the key features of the retul fit system?

Retül bike fit technology incorporates three main data points in fit theory:

Bike Fits Must be Dynamic: Most bike fitting specialists fit riders in a static position. This is because the traditional tools of the trade - tape measures and plumb bobs - do not allow accurate measurements while the rider is pedaling. Using motion capture technology, Retül records the rider's positions in motion, therefore creating the most realistic picture of the rider's actual pedal strokes and body positions when out on the road and trails.

Measurements Must be Accurate: Measurements made by traditional tools have one thing in common.  They are subject to human error and therefore can be devastatingly inaccurate. Even slight inaccuracies can drastically change the rider's feel after a ride. The Retül system is accurate to within less than a millimeter, creating true objective data which can be utilized by the fitter for the perfect biomechanical fit.

Biomechanics are Best Assessed in Three-Dimensional Space: it data collected in a traditional two-dimensional plane (i.e. video-based systems) is fairly limited because the fitter can only look at one view at a time, and those views stand as independent reference points. In order to make the best fit recommendations, the fitter must realize that the front and side views are actually interdependent reference points. In other words, the front and side views must be viewed simultaneously in three dimensions in order to see how all the applicable movements of the body are working together.  Retül uses a 3D motion sensor to simultaneously gather data on multiple angles of the rider.


WHAT HAPPENS DURING A BIKE FIT WITH RETÜL?

 The fitter does an initial physical assessment of the rider, and at this point can address the rider's concerns about performance, pain, or any other issues the rider hopes to alleviate during the bike fit. Once this is completed, the Retül process truly begins.

LED markers are strategically placed on eight anatomical points of the rider: the wrist, elbow, shoulder, hip, knee, ankle, heel, and toe.

As the rider pedals, Retül's sensor bar gathers real-time, three-dimensional data of the rider's pedal strokes and movements. Retül's rotating platform allows the fitter to collect data for both sides of the rider without the rider leaving the bike.

The rider's data is compiled into a reader-friendly report for analysis by the fitter. The fitter can then assess the rider's position and make necessary adjustments.

The Zin, Retül's handheld digitizer, allows the fitter to digitally measure the rider's bike at 13-15 points, depending on the bike. The Zin can measure fixed points, contours, and curves, and provides a complete digital map of the bike.

The fit information is saved and stored on the fitter's computer. The data includes the rider's personal profile, specific data and measurements from the fit, bike measurements, and the rider's final fit position. The fitter will be able to access and print these records for comparison and tracking of historical fit data for the client.

Dynamic fit bike with full XY adjustability to determine ideal riding position while a rider pedals the bike.

WHAT ARE THE KEY CONCEPTS OF THE RETÜL Müve FIT SYSTEM?

Key Features:Simple turn-crank movement allowing adjustment of saddle and bar positions while a rider pedals the bike Fitter can change saddle, stem, bars, pedals and crank length to find the rider’s ideal position and equipment for road, mountain or TT/triathlon positions Attains saddle heights of approximately 90 to 590mm Attains frame stack and reach of all production bicycles. The Muve fit bike also allows to compare several bikes in a time efficient manner. This way you can be assured that you are on the right size, and right geometry of bike.
Once the optimal fit parameters have been established, this data can be used to compare against all the bikes available on the market today.
