The Black Pearl riser is made from solid G10. It has a Bocote thumb rest and G10/Bocote back overlays as detailed in the riser features section. The G10 makes for a bomb proof riser and has more mass weight than any riser wood I've ever used. My 11" riser weighs right at 22 ounces, just over 1.5#. The amount of material needed for a solid G10 riser adds to the cost but makes for a very unique bow with great stability. The G3SS limbs use our super stable carbon layup back and belly with your choice of actionboo or foam cores. Black G10 limb wedge and tip overlays. Your choice of short, medium or long limbs on a 11", 13" or 15" riser for bows in 54", 56", 58", 60" or 62" length. All bows come with a D10 flemish twist string with wool silencers.
