I’ve had the same problems as a lot of people on here. Rockshox have just sent me a new pair after mine went back under warranty for the third time. Will see how I get on with them.
I reckon some of the issues could be caused by;
a. The manufacturing tolerances at Rockshox on this particular fork have slipped since switching to the solo air system. Solo air seems to be more of a money-saving move by Rockshox as I personally think it offers no performance benefit over dual air; in fact performance seems to be much lower than my old dual shock rebas.
b. The solo air system has some fundamental design flaws (e.g. the common issue of grease blocking the poz / neg air valve).
c. The new lightweight lowers are overly prone to flexing / warping.
It could be a combination of the above, or none of the above, but I’m really not happy with these forks, and it has put me right off Rockshox stuff.
I’m a light rider (69kg without kit) who predominantly rides XC with some trail centre reds now and again so I’m not ragging these forks. Unfortunately I’m stuck with them as decent new 1 1/8″ steerer forks are so hard to find nowadays.
