Retül Bike Fit

About Retül

Retül provides world-class bike fitting technology for all levels of bike riders

Why PhysioHaüs?

PhysioHaus is led by the most experienced Retul fitter in the UK (John Dennis) and as such works directly for Retul to train all the other fitters in the UK and other parts of the globe.  Tim works directly with John to ensure the quality of the work is of the highest standard.  As a physiotherapist with an experienced understanding of the biomechanics and rider assessment the Retul system empowers the fitter to make the best fit decisions when it comes to making adjustments to a clients bike. The reasoning skills behind what adjustments are made are based upon interpretation of the data by the fitter. The system itself doesn’t tell the fitter what to do. A common mistake is that you will have the same fit and position whichever Retul fitter you decide to go to. This is not the case.

Can I transfer my fit to another bike?

Each rider receives a document of their results that includes their individual range of movement taken during the fit and then using the ‘zin’ tool we accurately take measurements of the completed bike position. This allows the client to use the information taken to apply to another bike of the same type, similar geometry and frame size. Alternatively, we can utilize the Zin tool to digitally dial in a second bike.

How can a fit help or prevent injuries?

The fit session itself has several components to it. Each of these provide us with a picture of the individuals biomechanical profile which then has to be applied to the fit and the position decided upon. A  physiotherapy screening, an individual’s injury history along with biomechanics are taken into account during the process. Applying this information to the 3-D analysis ensures the best position for the rider. If you need ongoing injury management that can also be arranged through the clinic.

How long does a fit take?

On average, 90-120 minutes. Some fit sessions are more complicated than others either caused by the riders injury history or simply by their pedaling mechanics and sometimes large functional asymmetries. In other words the left and right sides can be very different!

What about LED placement?

The process is subjective but electrodes should be placed accurately to allow for reliable and valid data to be obtained. Our Lead Fitter is a Chartered Physiotherapist ensuring accurate and detailed knowledge of surface anatomy. This is a crucial part of the Retül fit process. Bad marker placement = bad data = bad fit decisions.

What do I need to bring with me?

To the fitting session, you will need to bring with you your bicycle, a set of appropriate cycling shoes and a set of shorts and short-sleeved top (ideally tight fitting to prevent any unwanted movement of the LED markers).

What does a Retül fit include?

The Retül fit process includes 3 components. Before the rider is analyzed on the bike, a physiotherapy screen takes place that looks at relative range of movement, flexibility and foot mechanics and structure. The findings are taken into consideration along with the dynamic fit data when individualizing a rider’s position. The client is then analyzed on the bike to obtain data on the position they are currently riding. Measurements are taken from both sides to look for any side-to-side differences- not something that is possible through a static or 2-D assessment. The results are then used to make any necessary adjustments. Data is taken again to view the affect of the positional changes. The aim of any fit is to obtain the most comfortable and efficient position and consequently the most powerful.

Why should I get a Dynamic Retül fit?

As the information is from dynamic data, not a static fit, what is actually happening during the pedal stroke with regard to range of movement is captured for analysis.

A bike fit using Retül technology typically includes the following steps:

  • 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.
  • 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, 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.
