A key component of the Compact Limb System Technology that powers the new TenPoint Phantom CLS crossbow, the 12-inch pultruded fiberglass IsoTaper limb is unique in that it is not ground to create a conventional hinge point like most limbs. Instead, it is ground to a static taper from thick to thin, starting at the butt end of the limb and extending to its hinge. The result is a limb of superior strength, without hot spots, that deflects relatively consistently across its entire surface.
