Improve your bicycle fork suspension

In this Instructable I will show you how to turn the regular coil suspension on a mountain bike into a shock absorber working on compressed air. With this Instructable you can save lots of money because the bicycle forks working on compressed air are usually quite expensive compared to the "normal" ones.

Step 1 Preparations

First I will remind you of that I take no responsibility of whatever you decide to do. Any warranties will probably be voided if you disassemble your fork suspension.  But I think that the chances of anything failing are very small since this modification is easy to perform.

This Instructable will NOT cause your bike to stop working with the old suspension system consisting of coils.
 
The parts you will need for this Instructable are:
-A bicycle fork that has a COIL suspension and rubber seals between the two legs
-A Schrader valve, I got mine from an inner tube for a bicycle tyre
-Epoxy glue and spatula
-An air pump
-Some cable ties (might not be needed)
-A hex key
-Some tools for bending (Leatherman, knife, flat screw driver...)

Nice instructable and idea. I like the idea, but I wouldn't trust my life to it, Sorry :( Anyway, how has this worked for you so far?

It has worked quite fine actually. My rubber seals are a bit too old, which means that the pressure is equalized in a few days, But the suspension is a lot better since my upgrade. With new seals I believe that there would be no problems at all.

I might actually try this with one of my spare bikes. But I'm getting the Rock Shox Tora shock soon, so I won't bother doing it to my Haro.
