Oversized Pulley Wheel System for Campagnolo 11-Speed

##CeramicSpeed Oversized Pulley Wheel System for Campagnolo 11-Speed The unique design of the CeramicSpeed Oversized Pulley Wheel System for Campagnolo 11-speed optimises bike performance by improving the efficiency of your drivetrain for a smoother chain through the derailleur, so you will glide up the hills and feel more of your watts transfer to top end speed when the sprint arrives. Specifically, this 13-tooth/19-tooth system claims to reduce friction by 40% over a standard 11-tooth Campagnolo pulley wheel. This OSPW system is compatible with all Campagnolo electronic rear derailleurs and all derailleurs with a mounting sleeve, with the current exception of Campagnolo 12-speed Record and Super Record derailleurs. **Please note:** When travelling, please remember to dismount your entire rear derailleur with an Allen key, as the OSPW System will not fit in most bike travel bags and could be damaged if left on.
