Retül Bike Fit at Sweet Pete's in Toronto

What is Retül bike fitting?

The Retül Motion Capture system is the most advanced dynamic bike fitting system in the industry. In the past, fitting has been limited to static measurements taken while stopping at specific points in the pedal stroke. While this is a good method, it does not allow measurements to be taken while actively riding. The Retül system captures real-time, 3D, millimeter-specific data from 8 anatomical points on each side of the body with extreme accuracy. 

The large amounts of data allows the Retül certified fitter to asses everything from the riders position to how they move on the bike, as well as asses any pain or discomfort while riding. They will look at individual points as well as how all the body moves as a whole.

The Goal Of A Bike Fit

The goal of a bike fit is to optimize balance and comfort in the overall position of a rider while they are riding their bike. 

As well as gaining efficiency, a Retül fit allows for compensation of injuries or anatomical imbalances, and in most cases leads to performance gains and improved comfort in the saddle over extended periods.

Retül has established optimal ranges for each angle of the body involved in cycling. This allows the fitter to make precise adjustments that are individualized to the rider while also making the rider more efficient.

How does the Retül bike fit process work?

You'll be in good hands with our professional bike fitter, who is certified by the International Bike Fitting Institute and is dedicated to giving you the best fit experience and results possible.

A fit can be done on an existing bike or upon/before the purchase of a new bike.  To get fitted before you buy we can use the fully adjustable Retül Müve bike that can replicate the fit of almost any bike and size, this allows the rider ton get perfectly fitted to the bike as part of the purchasing process.

Keep reading to learn how the whole process works.

Step 1: Personal riding history

We start all fits with Rider History. This includes past riding experience and specific upcoming goals, as well as past injuries and discomfort or pain experienced as a result riding.

Step 2: Physical assessment

After the Rider History, the fitter will asses the cleat position and perform a physical assessment. The physical assessment looks for any left/right discrepancies or tendencies in the physical makeup of the rider as well as assessing overall fitness and flexibility. 

Step 3: Gather fit data

LED markers are then placed on 8 anatomical points on each side of the body, and an initial video capture is done from both front and side angles. 3D data is then captured under various degrees of resistance on both left and right sides. 

The rider will be able to see themselves on the screen as it displays their movements in real time. Using the captured data the fitter will make adjustments to the bike/position and then re-capture. This process is repeated after each change until the rider is optimized and comfortable.

After all adjustments have been made a second video is captured and examined. From this and the initial video a photo will be extracted to display the changes.

Step 4: Apply the fit to a bike

The final step is to ‘digitize’ the bike using the Retül Zin. Using 13 points on the bike, the Zin creates a digital profile and precise measurements allowing the fit to be copied to additional bikes, or transferred to a new bike.

Step 5: Personal fit report

After the fit is done, the fitter will create a comprehensive report which includes:

  • a summary of the fit
  • an overview of what changes were made
  • an overview of the physical assessment
  • data from the final left and right 3D captures
  • pre-fit and post-fit photo’s
  • a Zin report with millimeter precise measurements of your bike

What is saddle pressure mapping?

New to the Sweet Pete's fit studio is the groundbreaking Saddle Pressure Mapping System developed for Trek by Gebiomized in Germany. The system analyses pressure from 64 sensors enabling us to accurately quantify pressure and better visualize the rider’s contact with the saddle. This allows us to make positive changes to the saddle and position on the bike arriving at the optimal position and saddle for any rider.

For a scientific approach to choosing a saddle, this system allows you to see precisely where your saddle pressure points are. Full analysis of saddle pressure points using pressure mapping tool and application.

Excellent for riders looking for a more comfortable saddle.

Valuable for riders who have left/right imbalances and are asymmetric on the saddle
