The use of CI4+ delivers a substantial weight saving on the compact Ultegra body making rod speed easier to generate when distance casting. To further increase casting performance the Ultegra uses 2 Speed Slow Oscillation line lay and an AR-C spool fitted with a Shimano Baitrunner mechanism. Cold Forged gearing and X-Ship produce powerful winding performance and 5 Stainless A-RB bearings plus a Shimano Roller bearing deliver supreme smoothness. The 14000 is supplied with 3 line reducers per spool, while the more compact 5500 is supplied with 2 reducers to cover any situation.
