Bike Fit Nice To Know Position Tips
When the bike fit is set up correctly you should not worry about injuries as your position on the bike is very good and let your muschles work accordingly. When looking at the bike fit your position on the bike is controlled by the 3 support points when you ride your bike:
- You sit on the saddle (at least mostly)
- Feet step on the pedals
- Your hands hold the handle bars
These 3 support points are the points, which are important with regards to sitting correctly on your bike. The distance and angle between each point is crucial to the correct set up of your bike and of course should be adjusted in proportion to your physical measurements.

The angle of your bike’s frame should fit your height. On a road racing bike the angle of the seat pillar in relation to horizontal is between 73-75 degrees. As your starting point, a person with long legs should have a bike, where the seat pillar leans more. If you have short legs, it is better to have a slightly steeper bike. Most bike makers are aware of this and the angle of the seat pillar varies in proportion to the size of the frame.

Most bikes are delivered with a standard pedal arm length, but you should be fussy when buying a new bike. Also that your bike should be fitted a pedal arm length suitable for your particular requirement.
Your choice of pedal arm length can vary from your regular road bike to your time trial bike and again be different on your mountain bike.
