I just got a hold of this and installed it to my Strida this morning. There are several positions that you can set based on your liking. I am still in the process of fine tuning the set up as my initial test ride is a bit to “springy” for me. One thing I note is that you need not level your saddle to the ground. Because when you sit on your saddle, it will compress so you have to compensate for that when setting the spring/device.
