On servicing the air spring on my 2015 Rockshox Sektor gold, I found a broken piece in the internals. Looked like a washer, circa 15mm across, in three jagged pieces littered around the internals. Thing is, this is exactly what TF found when they serviced the forks a little over a year ago. The bits had done some very minor internal scratching at that point. They reassembled the fork using all the proper bits. On cleaning the upper tubes, I can see some very small scratching, but fresh fork grease last time basically meant these mini scratches didn’t have much of a harmful effect.
Now I have done a strip and clean and reassembled, but obviously I didn’t put this part back in. As it has probably been broken and floating around in bits for the best part of a year, I don’t think I will die as a result. But if someone can tell me what the part actually is, I wouldn’t mind knowing. I recall seeing a similar post on Facebook from an occasional riding buddy about this too, so I think it might be a well-known Rockshox issue from 2014-15 ish.
Any thoughts?
Quick bump - if anyone out there knows the answer I’m curious as to what the broken (and now missing) part is........
Thanks.
I don't know anything about a sector but the wavy washer is a weakpoint on a boxer. Used to balance positive negative airsprings i believe. Might be that.
Thanks oldtalent. In terms of washers, I could still see two intact. One flat and one wavy that I believe are to do with positive negative balancing. These are both about an inch across, though. The broken one looked like it was about the diameter of the air shaft(?)
