The Carbon Express Maxima Triad XSD is a micro-diameter tri-spine shaft with a.166-inch inside diameter, built on Carbon Express's RedZone construction that stiffens the ends of the shaft and leaves the flex in the middle.
It is offered in three spines, 300 at 10.9, 350 at 10.1 and 400 at 9.2 grains per inch, each with its own outside diameter, and is sorted to +/-.002-inch straightness and +/-1-grain weight.
It ships with a spine-specific In-Out insert weighing 97 grains that carries the standard 8-32 point thread, so standard broadheads and field points fit.
