Summit, you need to chill out and read up. Your definition of high speed compression damping was about as backwards as, well, I don't know what.

Personally I think that reducing the travel on your frame like this was a pretty stupid thing to do, but hey, it's your bike not mine. IMO if you wanted an 8" travel bike, you should have gotten an 8" travel DH bike not a 9.1 and reduced the travel. I think it is safe to say most people think this has a much larger negative effect on the performance than it actually does though; you retain the same small bump compliance as you would with the full 9.1", it is just the bigger hits and compressions in the ground, or whoops if you will. Without changing the spring you haven't done anything to how the bike rides, and if you aren't hitting big enough stuff to go through the full 9.1" of travel, then all those little spacers are doing is adding weight and looking haggard.

That's my two cents.

 The CCDB is position sensitive, just like every other shock on the market, just with much less of an extreme change from the beginning to the end of the stroke. That's the whole point of having a pressurized compensator piston. Want proof? Take off the spring, compress the shock, and it'll come back on it's own eventually. They run 70 psi vs 125psi+, and it displaces less oil with the narrower shaft. Only difference.

Take it from a UC Mechanical Engineering grad, who runs a Double Barrel. A more noble way to achieve the same would be to make the air chamber size bigger and run a higher pressure to keep the same feel off the top, but make it more progressive in the last 1/3 of the stroke without affecting the midstroke after the sag point. Spacers work too, but they will compress. Try to get an aluminum travel limiting spacer off a DHX from a Specialized Demo 7, and run the proper bottom-out bumper from the CCDB. It works very nicely.

 Wow! Those comments from summit800 are getting annoying. This guy really don't know how the ccdb works. Good job on your mod.

I guess Specialized don't know what they are doing with the travel reducer on the demo 7

 Why do some people like starting arguments on the internet? I mean it's not like it should matter to them whatever you do with your shock...

 what does this complicated machinery do then?
