Tough Bar V4 AS

The Advanced Series bar, sold in 45 and 51 cm widths on a 22.5 m line set. It uses an anodized aluminium bar center in place of the V5's stainless steel, and its ceramic ball bearing untwists the front lines on its own after a rotation rather than needing a hand. Back lines are 1.5 mm SK99; the front lines are built in two parts, with a thicker 1.6 mm SK76 first 8 m for wear resistance and 13.5 m of SK99 above it for less stretch and drag. Front pigtails end in loops, back pigtails in knots. The low V splitter takes an optional high Y adapter, which mounts on a thickened section of the front lines about 5.5 m above the quick release.
