Orange aluminium 9 degree caster hub set (Xray XB4'15)
Heavy duty 7075 precision machined alloy caster hubs for the XB4 series (any XB4).
Machined down to 6 grams per hub for lightness but much stronger than the stock plastic hubs.
Polished and anodized in factory orange or black and laser etched for easy left right identification.
Matches stock geometry and still accommodates a set screw for the hinge pin.
Sold as 1 pair.
