The Black Ice FLX is just as dangerous as its namesake. Made even more so this year by the addition of the FLX-Guard, a cable containment system which addresses the tuning effects of high cable tension on today's premium bows. Draw your bow and the FLX=Guard flexes inward to absorb cable guard torque that normally transfers to the riser. Black Ice FLX advanced engineering and design delivers slick speed with absolute minimal hand shock and noise.
