1. Power the ShockClocks on and Start Recording.
2. Put the rider on the bike. Pavement – in standard riding position, dirt – standing on the pegs (this helps to make the numbers consistent because riders tend to sit in different places). Have the rider grab onto something for balance like a pole or the edge of a doorway. Having the rider grab onto something is preferable to having a third person hold the bike because the bike can be held more still.
3. Because there is friction in the suspension use this method of measuring Static Sag. Rear – push down on the rear of the bike about 25 mm (1 inch) and let it come up very slowly, particularly at the very end just before it stops moving. As it comes up it will stop. If there were no friction in the suspension it would continue to come up a little further.
4. Next pull up on the rear and let it come down very slowly, particularly at the very end just before it stops moving. As it comes down it will stop. If there were no friction in the suspension it would continue to come down a little further.
5. The actual Sag without friction is half way between these two points.
6. Repeat with the front end.
7. Have the rider get off the bike and measure Free Sag on the rear. This is done the same way as measuring Static Sag but without the rider on the bike.
8. Repeat with the front end.
9. To capture the point of full suspension extension (the zero point), put the bike on a stand or have someone assist you. Grab the bars and lift the bike until the front wheel is off the ground. This can be done at the beginning or the end of the recording.
10. Repeat with the rear by grabbing the chassis and lifting the bike until the rear wheel is off the ground.
11. Stop recording.
12. Download the files. Include the word “SAG” in the file names. |
