At first it is very unusual and feels a bit spongy, because you're just not used to the spring. After 2 days, it is perfectly normal.
I have installed the hard spring me before the first use. Simply unscrew the bottom, take out the old pen and make sure to sit on which side the two plastic parts at the old spring. Remove the rubber on the new spring and the old spring attach with spacers. The new spring greasing (I used lubricant from Shimano), the plastic parts to the right place and back into it in the bar. That's it.
In addition, I have oiled the hinges with Brunox Deo. Suntour recommends that about every 500 km or after cleaning of the bicycle when it was very dirty.
The saddle can be attached easily and is very well set the angle.
The only "disadvantage": The shape of the support of the seat is shifted 3-4 cm backwards. Anyone that can not be corrected with the saddle adjustment and the top tube is on the border too long anyway should only times sample sitting here.
To me, they must now hold only long. I love the new Comfort bon my hardtail. As long as you do not go singletrack or lot through the forest over roots etc. no longer need you as this fork, but still relieved his buttock and back.
From my full purchase recommendation. Especially at the price.
