When it comes to strength and lightness, the use of aluminium and Shimano’s proprietary XT7 material in the new Biomaster SWA series is a winning combination. Biomasters come in a choice of High or Performance Gearing with cold forged gears, also feature X-Ship, six shielded A-RB bearings and one roller bearing, 11-13 kilos of drag power depending on the reel model, plus a one-piece bail along with A-RC spool for resistance-free casting.
