XRAY have introduced new 71.5mm rear shock shafts for the XB8 and XB8E. The thick, robust 3.5mm rear shock shaft is precisely machined from special high-tensile steel and hand-ground for a super-smooth finish to ensure smooth movement in the shock body. It is 4mm longer than standard shock shaft to provide more droop. The 71.5mm rear shock shafts come in sets of two.
