Shimano AR-C Aero Ci4+ 4000

The AR-C Aero follows on from the success of the Aero introduction in 2013. Available in a versatile 4000 size, in both standard (4.8:1) and high speed (6.2:1) options, the AR-C Aero is made from technically advanced CI4+ composite for a huge weight reduction, just 255g. The combination of X-ship gearing and 6 Shielded A-RB bearings plus a roller bearing ensure maximum power and smooth performance. For easy accurate casting the Aero uses Aerowrap II line lay and an AR-C spool.
