Specialized epic 2004 manual

Dowel pins ordered for making a tool to unthread the reservoir piston head. Very cool. The rebound damping is handled on the piston in the shock body and the comp damping is in the remote or piggy back. The brass mass provides a way to remove the platform once the rear wheel hits a bump but the transition never feels smooth - you always feel a little "spike" before the system opens up.

If it was me, I'd be looking at ways to remove the brass mass, modify the adjuster to preload a LSC stack or modify the adjuster to control the comp free bleed. Suspension tuning has come a long way from when the brain first came out. The super-digressive stacks and their easy DIY tuning that come in shocks like the latest Monarchs mean the brain has really had its day, even on horst-link bikes like the Speci. You can look to the info of tuning the RT3 if you want some comp shim stacks to try.

Even though the shocks are different, fluid displacement on the comp circuit will be same as the damper rod is the same diameter.

So provided the free bleed is similar, the reservoir comp stack in the resi will see the same volume of oil flow as what the comp side of the RT3 piston will see. Also, there is really nothing in those pictures of your shock pull apart that looks like something made by Fox. If I had to take a guess, I'd say its made by Manitou. I can't imagine Fox making all new components just for a Speci brain.

Take a look at some pictures of the Manitou Q series of shocks and you will see many similarities - from the air cans, to the rebound adjuster, to the same design and seals used on the seal head. Last edited: Jul 20, I have started prototyping up an electronically controlled equivalent with a single axis accelerometer. That sounds interesting. You could do the same and chuck the accelerometer up front. Have you checked out the "magnetorheological fluid" stuff? That seems to be the way of the future for electronically adjustable damping.

Just dropped my brain shock off for a very expensive service so will be interested to hear how this turns out. And for those questioning if fox make these - they have since I took mine to Tekin and they send them on to Fox to be serviced.

The AUTOSAG feature automatically determines the correct amount of sag, and eliminates the need to refer to an air chart to determine the correct pressure based on rider weight. However, the shock still requires compression and rebound adjustment based on type of terrain and rider weight.

Rebound damping controls the rate at which the shock returns after it has been compressed, and is adjusted to your weight with click micro adjustments for rider style and terrain.

I saw how much satisfaction he now gets out of riding his own hand-built machine and, to be honest, it just looked damn fun messing around with the mechanicals and figuring it all out for yourself. I might give that a shot. So, the options. I do a lot of different types of riding, but one of the more important aspects is that I want to be able to go uphill.

Then the Heckler and that seemed to fit the bill as a sturdy but climbable machine. Then, my Specialized bias took hold again my previous 2 bikes have been Specialized… and I was looking at the Stumpjumper and the Enduro. In the end, fate decided for me. The S-Works models are the top of the Specialized product range and the S-Works Enduro differs from the others in that it incorporates the Specialized Brain technology for bob-free pedalling.

As someone who hoped to keep up with his hardtail friends this sounded pretty good to me. Even better, the model was the last to feature the old frame design before changing to the standard top-tube, bottom-tube style, and the more unique the better!
