They are extremely good. They even have the mylar insulation on them. It's better than the original factory insulation. My first cable had his old style ball stud. In order to make it the length we needed, he drilled and tapped a threaded rod and screwed the ball stud into it. That threaded rod portion inserted into the hole in the transmission lever and the nut was tightened down on the underneath side. Being hollow, mine rung off. Maybe I put a little too much UMPH on it, but a solid bolt wouldn't have broken. He's changed the design of the ball stud. You will need to save the body pass-thru grommet from the old cable. Rodneys doesn't come with that grommet.
Both cables were smooth and worked flawlessly. They are preadjusted to the correct length. There are several others who make the cables, but you often need to adjust them to obtain proper shifting.
