All this time I was under the impression that the NR front der was the best I have used. Hmmmmm. Never cared for reverse action front or rear derailleurs. Have 10's of thousands of miles on NR front der and it has always performed perfectly without trouble. I have also had the Cyclone MkII front der on a bike I used for about 10K miles and it performed well much like the NR. In general ft der rarely underperform for me.
