If you were going to buy a new one, you should not need servicing for quite a while, if ever, so why not just buy one? One thing I'll find out when I get into mine is how fast the oil tends to get trashed. There's some hard-pounding hours on my shock. If the oil comes out fairly clear, you all will be able to take confidence these things can get the crap beat out of them with little worry for servicing. I typically pour some of the oil onto a white paper towel to see the amont of particulates in the oil. I'll soon be receiving getting a back-up Reiger so I can confidently get into the Reiger in need of servicing to do so and display its guts here. Speculation by three of us now is this is a bladder accumulator shock, and not piston accumulator (DeCarbon-style piston separating gas from oil). We need a USA source for servicing these things, and I or another should be able to do so. The factory's caution against just any old servicing effort is understandable, as they are trying to prevent problems from poor rebuilds. Sometimes the special tools are needed, sometimes the lack of them just adds to the time to service one.
