I bought my 2012 Trek HiFi Deluxe about this time last year. I read a good bit about bike tech before buying, so was familiar with maintenance issues on some items, such as the Fox RP2 shock. Being the overprotective new dad for my new baby, I decided to try and protect against dust on the shock. I ride on some pretty dusty trails. Anyway, I sheathed the fully extended cylinder of the shock with a segment of old 1.5" dia. inner tube. I squirted a liberal amount of graphite into the inner tube segment before cinching it into place with a cable tie on each end.
Seems to have worked like a charm so far. Instead of getting bathed in a fine dust of ground rock during each ride, the cylinder is bathed in a fine dust of graphite dust instead. Can’t say for sure if it’s helping, and I’m still going to order some new seals for this coming season, but I wanted to share the idea, in case anyone is interested. It’s very cheap/easy.
Anyway, I can attach some pix for anyone who may be interested. Not sure how to use the img tag above, however.

There’s nothing wrong with protecting your investment, but mtb suspension forks and shocks are built to withstand the punishment of dirt and grime. I perform regular maintenance on my fox triad and rock shox Reba and have yet to find any kind do build up in the chambers. The service kits include new dust seals and I change them out a couple times a year. Thanks for sharing though, I would be interested in seeing your set up.

How do you check sag with that protection on?

My understanding is most manufacturers recommend against covers like that. The problem is they can’t keep everything out, so what gets in ends up trapped inside. Most recommend just wiping down the stanchions every ride or so.

I’m wondering about putting powdered graphite in there. Isn’t that counter-productive to the dust protection? Graphite dust is super-fine and I’m wondering if it could actually get by the seal? I used to machine graphite and would wear all sorts of protective equipment. Even so, the graphite dust would worm it way in everywhere.

A dust protector to protect your dust protectors. It’s ingenious. While you’re getting ready to market your product, I will secretly be designing a dust protector to protect your dust protector that is protecting the shock’s dust protector.
Who’s got two thumbs and is about to be a millionaire? This guy right here.
Joking aside, The Lizard Skin shock cover is so cheap, You’d have to value your time akin to a child laborer in China to beat the price.

Good luck, if the graphite makes it way into the shock. That’s probably worse than any dust that might get in.
