If you want fast shifting, you want the interface between the cable housing and the cable to be as slippery as possible. Gore's RideOn Professional Derailleur Cable System utilizes an entirely new cable coating that is specifically designed with road shifters in mind. A housing lubricant was developed in parallel with this coating, providing the lowest friction cable system to date. This is the latest addition to the RideOn cable line, which was reintroduced in 2007. The first go-round, the coating on the cable, an essential part of the system, was about 10 times thicker than it is currently. That made the earlier iteration less flexible and not as smooth-running inside the housing. This coating makes the cable little different than a standard derailleur cable, other than it's slickness.Gore coats the majority of the cable and that coated cable runs smoothly inside the lubricated derailleur housing. The first four inches of cable starting at the head are uncoated, in order for the derailleur cable to spool and unspool smoothly inside road shifters where the cable passes over the body of the hood. In addition, the cables are protected by Gore's Ultra-Long Nosed Ferrule - which protects the cables from the elements along the downtube and under the bottom bracket. Finally, Gore's GrubTM seals seal the ultra-long nosed ferrules to protect the cable within.RideOn Professional derailleur cables incorporate 4mm housing and will work with all SRAM Double-Tap road shifting systems, all Campagnolo 10- and 11-speed Ergo Levers, and both Shimano's internally-routed STI and old externally-routed STI road levers. They manage this by putting two different cable heads on each cable. One end has the Shimano/SRAM 4.4 mm diameter head, the other the Campy 4.0mm diameter head. Cut off the one you don't need. The system comes with 2050mm of lubricated 4mm cable housing, which you cut down with a cable cutter for your front and rear mechanisms. It comes with a 1900mm front derailleur cable and a 2200mm rear derailleur cable. It comes with a total of six ferrules. Two for the shifter housing stops (one for the left, one for the right), Two ultra-long nosed ferrules for the cable housing stops on the down or head tube of the frame, a standard nosed ferrule for the chainstay housing stop, and a standard ferrule for the housing stop on the rear derailleur. Along with these ferrules, come two grub seals. One goes on the front derailleur cable just below the pinch bolt. Another goes on the rear derailleur between the pinch bolt and the derailleur body. And along with the Grub seals are two red crimp cap covers to show the world you're running RideOn cables. The claimed weight of a Gore RideOn Professional Derailleur Cable set is 69g for a 56cm frame.
