The sleek carbon fiber and titanium, un worn out, Specialized Future Shock FSX Rock Shox was not holding air in one side. I liked this damn thing, it’s perfect for street riding; light, compact, and short travel.
I went to start a tear down and investigate what could be the problem. Of course, I want to do the least amount of work possible, so I start with what I can do on the exterior. Under the boot, there is a internal snap ring retainer clip holding the interior guts inside.
First, let the air pressure out of the forks, then use snap ring pliers and remove that retaining ring.
First thing to try is to fold that lip back down. I was able to poke it down, snug along the stanchion, with a nonscratching plastic tool. Then replaced the snap ring.
Whodathunkit, the damn thing worked. It holds air and slides better than ever. I imagine that in the future it will blow out there again; but as long as I avoid the big air jumps this fork will keep performing well.
I was able to inspect my complex machine, determine the problem, and solve the problem, with the utmost of economy; and avoid a complete teardown and overhaul.
