Perfect suspension? Square edge front suspension test

Описание: Front suspension test.
Front suspension has position sensitive compression dampers.
Front springs are 0.42
Rear suspension is standard shock with a stiffer spring to match the front. Rear compression clickers completely opened, rebound in the middle of the range.
Test track length 2.4m.
Frame rate 240fps
Large bumps 150 high x100mm, small bumps 100 high x100mm.
Bump pitch 720mm.
Speeds have been calculated by counting the number of frames a movement takes.
Bike from frame rate 43kph (12m/s)
Bike speed from speedometer 40kph.
Front suspension first impact compression speed 12m/s
Rebound speed 3m/s.

Things to note:
During the test there was no action taken by the rider to prepare for the hit. The bike simply rolled over the test track.
Front suspension rebound speed is over 3 times faster than rear however front suspension bounces significantly less than rear suspension.
At time 14 sec note the tyre hitting the ground and compressing. The tyre rebound did not cause the front suspension to bounce significantly. Noting the shape of the tyre on the ground it is possible to see the change in force from the suspension by looking At time 16 sec note the rear tyre hitting the ground and bouncing significantly more than the front tyre even with the rear suspension rebound being much slower than the front.
Also note at time about 13.9 the force of the impact is such that you can see the 48mm forks bending slightly.
Note that the front part of the frame barely moves while going thru the bumps.
During the first bump it appears that the frame starts to move upwards after the front wheel has cleared the bump. The reason is that after the wheel gets to the top of the bump it is moving so fast that the force of from the suspension is not enough to slow down the wheel before the suspension bottoms out. This is why the frame moves after the first bump has been cleared.
The front suspension is setup firmer than the rear suspension. see    • Front and rear stiffness comparison   for a video on the firmness of the front compared to the back. The front suspension is considerably firmer than standard suspension.
This allows for low dive during braking or landing of jumps without sacrificing plushness on small high speed bumps
