Exoskeletal hybrid construction combines an ultra-rigid aluminum alloy in load-bearing areas with a lightweight composite for a 50% weight reduction in non-critical locations. This allows for the lightest possible frame with no sacrifice in strength. 38% stronger than magnesium and 6x stronger than a graphite composite frame. Single-piece aluminum frame is machined with computer-guided precision to hold all critical components in perfect alignment. PT drag systems feature ceramic washers to dissipate heat during long runs. Customized, high-grade stainless bearings minimize vibration and friction. Special polymer cage for added sensitivity and corrosion protection. Polymer-stainless hybrid PT bearings. Lightweight aluminum crank handle. Continuous Anti-Reverse. MaxCast skeletal spool. Quick-release side cover. Adjustable centrifugal cast control.
