I ran the PC pull rods in 1993 & 1994 (Sold the bike after that). I then purchased the ones pictured here in 1995 & have used the same set ever since (remove them from the bike prior to sale) and have not had any wear issues.
KXCam,
I agree an inexpensive way to get by is to use something else, but, at any time you want to change your set up with these, its as simple as removing 1 bolt & nut spinning the insert and go from a Woods Slicing Machine to a Whoop Hound. I have tried different many setups including Triple Trees with less Rake, but nothing has come close to the difference these make as far as front end "Bite" for me.
