This presentation:

• Why the ideal bike position?

• BackgroundsPerformance, muscles, pedal movement

• Determine position

Part 1

Why is it so important to ride with the ideal position ?

11.1.2000 4

Goal

• Faster biking

• Longer biking

• Less fatigue

11.1.2000 5

For who?

• Sports orientated Cyclist

• Mileage freaks

• Occasional bikers

11.1.2000 6

Incorrect bike position can lead to:

• Knee problems

• Achillestendon complaints

• Back problems

• Painfull arms, shoulders and neck

11.1.2000 7

Determine position to…

• Optimum perfomance– Musclefunctioning– Breathing– Aerodynamics

• Relaxed and painless rides under all cicumstances (sprints, climbs, descents, timetrials)

Performanceparameters

• Muscle functions

• Levers

• Breathing

• Biomechanica

• Aerodynamica

• Comfort

11.1.2000 10

Muscle

Conditions:• Energysupply (Fat, Carbonhydrates)• Blood- and oxygen supply• Reach of the movement• Pretension before maximum effort

11.1.2000 11

Pedal pace

• Slide

• Tension

• Pull

• Push

Max. Force

11.1.2000 12

Movements

• „Picking“Pedal movement from top till bottom

• „Kicking“Rotation of the shinbone around the knee

• „Piano“Movement of the feet

11.1.2000 13

Muscles related to pedaling:

Stretching (1,2 and 3)

Bending (4,5 and 6)

1. Calves

2. Quads

3. Calves

4. Adduscors

5. Glutes

6. Lats

11.1.2000 14

Pedal pace rotation:

11.1.2000 15

Pace

• The full rotation leads to a gradual load and unload

of all muscles involved.

• Ideal combination of:– Picking-– Kicking-– Piano

11.1.2000 16

Part 3

Determine position

11.1.2000 17

Incorrect bike position can lead to:

• Knee problems

• Achillestendon complaints

• Back problems

• Painfull arms, shoulders and neck

11.1.2000 18

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

11.1.2000 19

Sitting parameters

• Position of the foot

• Angle in knee joint

• Positioning hips

• Positioning of the back

• Arm position

• Body gravity centre

11.1.2000 20

Positionparameter

• Seat height– Saddleheight– Saddle lay back

• Handle position– Length– Height

• Cranklength

11.1.2000 21

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°

11.1.2000 22

How to get to the ideal position:

• Adjustment and try outs

• Mathematics

11.1.2000 23

Cyclefit calculation

• individual

• simpel

• reproductive

• Scientifically proven

• Field experience

11.1.2000 24

Taking measurement

Saddle position:Innerleg length, upperleg length , foot length

• Position of the handlebarchestlength, Armlength and Schoulderwidth

Fast, simpel and reproductive

Result

• Accurate• Scientifically proven• Field expierence

11.1.2000 27

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

11.1.2000 28

Cyclefit

• Precise measurement

• Exact adjustment

• Beter biking
