Can aftermarket 32mm Dust Seals and Foam Rings be used on my Rockshox Recon?
You need to check whether your fork uses flanged or flangeless seals. Both are available for 32mm stanchions, and it’s specific to each model which version is needed.
I’d just perform a service without changing the seals. If you insist, the foam rings should be fine (it’s just a open-cell foam ring, duh), but I wouldn’t want to use the third-party seals long-term. There’s no guarantee they seal as well as the real deal or that they have similarly low friction levels. It’s not worth it saving a few bucks while risking expensive fork damage, and your existing seals will survive another few months or however long it takes to track down the right kit.
