So I have an 04 (I think) Rockshox Duke SL Air. I did notice that it was leaking air very slowly, meaning I'd have to pump it up once a month or so, but recently it won't even do that. Now it doesn't hold air at all.
So how difficult would it be to replace the seals? I do all of the work on my bikes, but have never even attempted to play with a fork like this. What sort of tools and fluids would I need? Should I just say screw it and bring it to the shop?
