XRay X4 Graphite Upper Deck Split Rear 2.0mm

The XRay X4 Graphite Upper Deck – Split Rear (2.0mm), part number XR301073, is the rear section of a two-piece top deck designed primarily for asphalt tracks. Precisely machined from 2.0mm graphite, it includes milled holes for tweak-free top deck screws. The split layout enables independent front and rear flex tuning, delivering greater steering response and stronger on-power steering, while its shape targets maximum traction with balanced steering characteristics.
