Incorrect bike
position can lead to:
•
•
•
•
Knee problems

Determine position
to…
• Optimum perfomance
– Musclefunctioning
– Breathing
– Aerodynamics
• Relaxed and painless rides under all
cicumstances (sprints, climbs, descents,
timetrials)

14
Pace
• The full rotation leads to a gradual load and unload
of all muscles involved.
• Ideal combination of:
– Picking– Kicking– Piano

17
Incorrect position of
the saddle:
• Too high
– Moving on the sadle
– No efficient pedalling
– Overload of knee
• Too low
– overload on the knees
• Too far to the front
– Unfavourable lever, overload on the knees
• Too far to the back
– Unfavourable lever

The ideal position
• Knee angle of 145°-155° (pedal in
lowest position)
• Knee joints above pedal axle (cranks
horizontal)
• Angle sholder/upperarm approx. 90°
• Angle elbow joint approx. 160°

Result
• Accurate
• Scientifically proven
• Field expierence

26
Cyclefitpositioning
• High seatpositioning (not too high)
– Full force development without over streching.
• Streched seatpositioning (not overstreched)
overstrekt)
– Streched back for good oxygen intake
– Correct arm angle for more comfort and to
prevent fatigue
– Relaxed neck muscles
– Aerodynamic position
