KIZER Suspension Skeleton Frame White

Original description from the manufacturer:
Suspension frames help cushion impacts and vibrations from rough surfaces. Kizer's all-new Suspension Skeleton frame allows skaters to roll on a wide range of wheel setups, making it easy to find the perfect setup to compliment your individual skating style.
From flat to anti-rocker setups, the Suspension Skeleton incorporates a strong fixed single lock steel axle for fast wheel rotations, while the interchangeable framer rocker spacers allow skaters to move the wheels up or down a full 3mm.
This innovative frame also incorporates a central groove shape that virtually eliminates wheel bite.
At only 235g (size small) per frame, the Kizer Suspension Skeleton frame is incredibly lightweight. It's also designed around the popular UFS mounting system allowing skaters to attach the frame to an extensive selection of boots.
Here are your setup choices without the suspension system built in:

Flat (no suspension):
Bearing bosses rockered UP - Max 60 mm wheels
Bearing bosses rockered DOWN - Max 65mm wheels
Antirocker/Freestyle (no suspension):
Bearing bosses rockered UP - Max 60 mm wheels
Bearing bosses rockered DOWN - Max 65mm wheels
Antirocker/Freestyle (no suspension with a recess in soulplates):
Bearing bosses rockered UP – Max 65mm wheels
Bearing bosses rockered DOWN – Max 72mm wheels

Please note that the Skeleton body does not include any hardware. Axles, spacers, and other components are sold separately.
