The KIZER in line skate suspension frame is the latest in line skate frame from KIZER in line skating company. The specifics on this in line skating model are its suspension bushing and pivotally mounted swingarms.

Explanation:

One suspension in line skate frame consists of three parts: An in line skate suspension-grindblock and two suspension-arms (swingarms). The in line skate suspension-arms are mounted on pivoting axles (Main Pivots). Between the grindblock and suspension-arms are two Suspension Pads which are shockabsorbers that let the suspension in line skate frame absorb impact. At the backside a slightly harder Suspension Pad is placed (red), as the pressure is harder on the heel than in the toe. The middle hard Suspension Pad in the front is yellow. For buying later there are also softer shockpads available (color: clear). These are suitable for skating completely or only in the front and use  the yellow Suspension Pads at the heal. The Suspension From Kizer is customizable for weight and rider ability - this is the only frame that allows such customization.

What is the advantage of a Suspension in line skate frame? First, landings are better absorbed after very high jumps. This prevents knee and back impact. Second, obstacles on uneven ground can be run up easily.

KIZER Suspension in line skates are equipped with UFS to fix the frames on all boots/uppers available with Universal Frame System

Assembly Instruction For KIZER Suspension Frames:
When you order some KIZER Suspension Frames you should receive: 

- 2 grindblocks (H Blocks) - 4 swingarms - 4 Shockpads (2x yellow; 2x red) - 8 Axles - 8 screws (Go into axles) - 8 frame spacers - 4  bearing spacers - 4 UFS screws

The frames are shipped pre-assembled

1st step: Check the completeness!	2nd step: Remove pre-assembled axles! Remove the pre-assembled axles on 2nd and 3rd wheel position. Please loosen the screws and push out the axles.
3rd step: Loosen Swingarms! (2 different ways -easy and hard!) 1st way: If you pull really hard you can pull the swingarm arm from the grindblock (Difficult).	2nd way: Between grindblock and swingarm you can put a tool and lever/PRY the swingarm from the grindblock. This is easier and the suggested method.
4th step: Check and sort all components! Before you reassemble the frames, you should check if you got all components: - 1 grindblock - 2 swingarms - 2 Shockpads (1x yellow ; 1x red) - 4 axles - 4 screws (Go into axles) - 4 frame spacers - 2  bearing spacers - 2 UFS screws	5th step: Mount the grindblock! First mount the grindblock without swingarms with the UFS screws.
6th step: Mount the swingarms! First lay down the shockpads on the mounted UFS screws. VERY IMPORTANT: The yellow shockpad has to be mounted on the front and the red one on the back. Because the heel has more pressure than the toes.	Then put the swingarms back on the grindblock...and snap into place. Now ready for the swingarm axles.
... and fix it with the axles!	7th step: Mount the wheels! Before you mount the wheels you have to put the frame spacers from the inside into the frame. The frame spacers keep the space between the wheels and the frame and allow the bearings to ride fast.
Then put one bearing in the wheel. Now put in the  bearing spacer from the other side. After that you can push in the other bearing from the other side. These  bearing spacers keep the space between both bearings and guarantee the strength of the wheel.	Now you can mount the wheel in the frame. Please fix the wheels with the axles and the screws.
