New innovation and new XRAY patent the XRAY Adjustable Rear Hub. CNC-machined from premium lightweight T6 aluminum, polished for luxuriuous and stylish appearance. Ultra-strong rear upright provides very long life and durability in even the most extreme racing conditions. The rear upright features composite bushings which have the hole positioned off-center, which can be inserted in the bottom of the block where the hinge pin is mounted.
