OYSI Oy3x Caleb Smith Pro Model Frames

The longer 283mm wheelbase incorporates a microrocker to promote agility at lower speeds yet retain stability at higher speed.
OY3X is a UFS (universal frame system) based chassis, which is the standard mounting system for aggressive/street skating boots.
OY3X is also specifically designed to be installed on the REC boot standardized 165mm mounting system by using a custom UFS RISER/REC ADAPTER (4 of these are included with each OY3X package).

UFS Boot Mounting options:

•    3 x 100mm @ 247mm wheelbase (min/max 100mm wheels)
•    3 x 110mm @ 283mm wheelbase (min 100mm wheel / max 110mm wheels)
•    3 x 125mm @ 283mm wheelbase using 2x UFS RISER (min 100mm wheels / max 125mm wheels)

REC Boot Mounting options:

•    3 x 100mm @ 247mm wheelbase using 1x REC ADAPTER at heel (min/max 100mm wheels)
•    3 x 110mm @ 283mm wheelbase using 1x REC ADAPTER at heel (min 100mm wheel / max 110mm wheels)
•    3 x 125mm @ 283mm wheelbase using 1x REC ADAPTER at heel (min 100mm wheels / max 125mm wheels)

The OY3X chassis and UFS RISER/REC ADAPTER adapter work together, providing a specific slotting to allow the chassis to be properly aligned about the center of the foot when mounting to a Recreational boot with the standard 165mm REC mounting specification.
