Saddle Height

Comfortness in doing cycling activities is not only depends on your seat position, but also the height. You can adjust the seat height to your feet length accurately by doing these things:

1. Tighten your seat. Place your ankle onthe pedal with the nearest position to the ground. Make sure the crank is on the vertical position.

2. If the heel of your foot points down about 30 degree , the height of the saddle is correct.

Cautions!


Make sure that the border mark on the seatpost is inside the frame already. If it is not possible to reach the right height of the seat, you have to choose the longer size.

The ideal position of these at is horizontal. Consider the parallel position of the seat with the top tube of the frame.


Make sure that the seat is correctly place down the seatpost,and the QR seat pin position to the inside more or less parallel with the top tube.
