XB4 12 ALLOY CASTER HUB SET

See: Exotek

Exotek introduces new 12° caster hubs for the XB4 series (any XB4). They are precision machined from heavy duty 7075 aluminium then polished and anodized in glossy black and laser etched for easy left right identification. They are machined down to 6 grams per hub for lightness but much stronger than the stock plastic hubs.
