Diamond Stud, Hardwood Grey: Brace Height 7", Axle to Axle 33 1/4". Draw Length 25" - 30", IBO Speed 310 - 318 fps, Kinetic Energy 78.6 fpe, Adjustable Let-off 65% - 80%. Single Cam and built on an all new riser design. With its customizable valley and single rotating mod, this smooth-drawing "Stud" can be dialed into individual shooting styles. It also features optimized mass placement for reduced shock and noise and increased efficiency. To further reduce noise and vibration, the Diamond Stud utilizes the new string supressor technology that is directly in line with the stabilizer bushing to transfer vibration away from your hand. Vertical Force Technology (VFT) disperses any power not converted directly into arrow speed away from the riser, equally in opposite directions virtually eliminating hand shock and recoil.
