Shimano Launches Bike Fitting Program

Shimano integrates the Lite measurement into the Shimano Official Service Point (OSP) concept. has developed exclusively for Shimano the easy to handle Lite measurement, for optimal “customer service”. With the modern designed display, you only measure the total height and the height of the sitting position. On base of this excellent rapid measurement, the frame height and adjustment of the bicycle are calculated.

The Shimano Lite measurement provides 7 types of measurements.

In the last few years more and more attention in the cycling sport has been paid to coaching and supervision of the cyclist. So much progress has been made, particularly in the field of training and nutrition, that the physical performance has nearly reached its optimum.

In order to further improve the efficiency of the cycling movement, optimizing the position on the bicycle is an absolute prerequisite. The ultimate aim is to achieve a position of the cyclist on his bicycle which is as efficient and as aerodynamic as possible.

If efficiency were the only factor demanding attention, it would be fairly simple. During this last decade, the cycling sport has evolved from an endurance sport into a power-endurance sport. The influence of biomechanic and aerodynamic research is gaining importance. The goal is to find a cycling position in which power is maximally converted into motion.

Scientific and empirical research has shown that a correct position on the bicycle is determined by several factors.

The matrix that illustrates the correlation between these factors consists of the following elements: friction, efficiency, power maximization and comfort.



Power maximization


In reality, however, the results of this research are not always used to its full extent. It is apparent that many cyclists, and not only the recreational cyclists, still adopt a very poor position on their bicycle. This clearly illustrates that the vanguard of the cycling sport has so far failed to appreciate the effect and use of biomechanic and aerodynamic research.

A proper sitting position on the bicycle has other advantages, also. Cyclists are regularly confronted with injuries, and cycling tourists face physical complaints in large numbers. These injuries and complaints are caused by deviations in position or by an incorrect position on the bike.

The Basic measurement is the start-up of the measurements sytems Its designed for adjusting standard bikes used daily or for recreational purposes. The Lite Analysis takes into account the following measurements:


torso length

arm length

This data will be added to the computer program and the result will be a design that will show you the dimensions of the frame and the position of saddle and stem. A properly adjusted bicyle is the ideal condition for many kilometers of cycling fun.

The Standard Analysis calculates the ideal bicycle size and position of the cyclist. With the help of a computer drawing, each client can make an educated choice of which new bicycle fits. It can also be used to perfectly adjust an existing bicycle.

It can also be used to perfectly adjust an existing bicycle.

The Standard Measurement Jig is used to precisely determine eight body dimensions.

The model of shoe (sole thickness), pedal (height) and type of saddle are also taken into account.

The bike measurement program at also includes a module that translates the ideal frame measurements for a race bike and/or MTB into the best fitting measurement of a specific bike manufacturer.41 different bike manufacturer brands were included in this module, named the .

The Professional Analysis is the most extensive service. It is specifically designed for athletes who strive for absolute optimization of physical performance or those with particular physical problems, especially related to hip, knee and ankle functions. Building on the results of a

The Position Simulator has three functions:

To determine the exact seat angle of the frame, which is a direct result of the ratio of upper and lower leg length. This also calculates the correct fore-and-aft adjustment of the saddle which assists optimal power transfer and a stable position on the saddle.

to compensate, for example, for differences in leg length which often leads to pain in the lower back area.

To simulate the position that the computer program has calculated and to enable the client to immediately experience this improvement.

Motion Analysis

The Motion Analysis provides a very precise picture of the biomechanical aspects of cycling. Motion Analysis analyses the motions of the knees, shoulders and pelvis. The motions are analysed in real-time under high loading factors. Two cameras follow the motion of both knees, the shoulders and the pelvis. During this dynamic analysis, any deviations or irregularities in the pattern of movement are quantified very precisely. While cycling, the biomechanical picture changes under the influence of the motion and the loading factor (the applied pressure). Small biomechanical deviations are magnified as a result. For example: a cyclist with a small between both legs can usually sit up straight on the bicycle, but when subjected to a (heavy) load, the pelvis will start moving asymmetrically.

The unique advantage of Motion Analysis is that it makes it possible to immediately visualise the effect of possible modifications and adjustments.

Professional measurement

The Analyser determines the exact proper of the frame. The correct seat angle follows directly from the ratio of upper and lower leg length and is displayed digitally. The final result is a correct sitting position relative to the crankshaft, leading to optimal power transfer and a stable position on the saddle.

The seat angle measurement can be carried out quickly and easily. It is also closely linked to the practical experience of the cyclist, as the cyclist’s own bicycle is taken as point of departure for the measurement.

Digital Calibrator

The Analyser can digitally calibrate a bicycle with regard to the following settings/adjustments:

saddle height

saddle setback

difference in height of saddle and handlebars

distance from saddle to handlebars

The Digital Calibrator is built from components used in the machine construction sector, including a precise guidance system. A laser pointer ensures that the measurements are read out very precisely.

The Digital Calibrator only measures and reads out the points of contact between the cyclist and the bicycle. Accordingly, the specific frame geometry does not play a role in making adjustments to the bicycle, unless the geometry deviates so greatly from a correct geometry that a correct adjustment is no longer possible. In such cases, the importance of a correct frame size and geometry becomes very evident.

The screenshot below illustrates the optimum X- and Y-coordinates deduced from the measurement. The Digital Calibrator translates the measurements and applies them to the bicycle.

In addition, the Digital Calibrator can copy the exact position and geometry of one bicycle to one or more other bicycles.
