First of all, there are not enough strokes. It weighs 53 kg, but when I make it a big stroke, I feel a bottom throw. That habit, fine unevenness can not be absorbed, and it transmits vibration vigorously. The fluffy fluffy absorbs the shock with a nice touch, but in that situation I felt it was unnecessary. I was on the road for a while, but this time I heard a sound like a chewy gum and a ponkut car and it was a really disappointing item.
I replaced it with a pain relieving purpose because it has low back pain, I was slightly lighter or a spring is too solid or not improved much. Making is good, but I also supplemented the oil, but I want a little more elasticity a little sorry.
