1, it is directly establishing buffer gear in order to the foot lever that supports whole machine body, and runners produces relative swing with whole machine body, so its whole machine body is more unstable.

2, its whole machine body acts on buffer gear, the bigger load of salty this buffer gear of shape, and buffer component can close the angle phenomenon because of relative rotation produces, so its service life is not long yet.

3, as mentioned above, this commonly uses product whole machine body (even together with runners) swing buffering, forms utmost point wild effect, influences the stability and the smoothness of running relatively, causes runner's discomfort.

4, as mentioned above, formation vibrations by a relatively large margin that this commonly uses the product whole machine body because cushion reduce original rigidity of its mechanism and stability relatively.
