Ultegra XTB The Ultegra is Shimano's flagship surf casting spin reel, and it's upgrade to Ci4+ rotor and body delivers a threadline that is substantially lighter to hold, yet stronger too. X-Ship provides better gearing and power, while the Aero Wrap II oscillation system delivers uniform line lay on it's big pit AR-C spool, so casting to distant gutters and bommies has never been easier.
