Gore Ride On and Bontrager

With newer designs and wider and ever engorging bottom brackets, the front derailuer cable now has to thread through part of the frame. One of the criticisms of the design is that a small plastic sleeve is actually placed just when the cable curves up. Maintainance is an issue as dirt and gunk tend to built up much more easily.
Enter the Gore Ride On Sealed system with teflon cables which are said not to need lube during service. You can feel the 'teflon' immediately as you try to pull the cable to tension before screwing in the bolt clamp. Any difference in shifting? Not that I could notice, but I do not shift the front that often and the old cable arent that old to start with.The cable is pretty easy to install. Time needed: 30min max. The plastic sleeve runs all the way through.Cable/frame 'donuts' tend to slide up and down and congregate at an area after a while. Not much use. Install some Bontrager rubber sleeves/widgets on the outer cable.
Time needed: 20mins!! The are a pain to get onto the cable but once at the required location; DOES NOT MOVE.
