How you doing Fabio?

[Mike Bike]

Mags, is the excessive sag a new occurrence? It sounds like something has gone wrong with the internals of the shock. I would suggest taking it to JB..he will be able to advise you accordingly and repair the unit as necessary. I cant imagine replacement would be a cheaper option..but i stand to be corrected as i ride a HT. Hope this helps

HEY MAGS - I'm gonna help you out here and get the grammar Nazi's off your back so you can actually get some real advice (thanks Mike) and not "chirps".

 

Hi.

 

My name is Mags.

 

I require some assistance with my rear shock on my Specialized Stumpjumper. It is a 2010 model.

 

At the moment i am experiencing severe sag on the shock, despite increasing the pressure from 160psi to 200psi.

 

Even at 200psi the shock compresses approximately halfway with my body weight on it.

 

If one of you kind gentleman cannot advise me on whether or not the shock can be repaired, can you please advise if it can be replaced with a Fox DHX model shock.

 

I really appreciate all the grammatical help from my fellow hubbers, but i would appreciate some RELEVANT shock related advice (thanks again Mike) even more.

 

Thanks

 

Mags.

 

Thanks Wayne, now I understand.

 

To the OP:

 

Most Specialized shocks have a special mounting that's unlike those on other bikes. Therefore I doubt that you can replace it easily with something else. There are exceptions such as the older Stumpies with the shock behind the seat tube. I think those can be converted.

 

Send us a picture of yours and I'll take a look. However, the solution is in finding the real problem.

 

Shocks are two-part affairs. The one part is the spring (in your case, it is an air spring that you pump) and the other part is the damper. Only the spring has an effect on the amount of sag you get on the bike. Sag is how much the shock depresses when you sit on it.

 

The damper could have an effect on sag if it is a lockout type shock, but lets take that out of the equation. Then you are left with the spring. Either the spring is hard or it is not. In your case, you don't say whether you've tested to see if it holds pressure. I suggest you pump it and then smear a strong soapwater concentration on the shock and look for air leaks. These will show up as bubbles.

 

If there is an air leak, we've found your shock's problem.

 

The other problem could be that the inertia valve (lockout) on that shock doesn't work anymore and it now feels different to what you're used to. But lets first determine whether it leaks air or not.

The shock on a 2010 stumpjumper has a specific eye to eye length that is unlike most stock shocks (most Specialized bikes are like this), but there is a walk around if you don't want to replace it with the same shock: you can get www.pushindustries.com to adjust the shock of your choice to fit that frame.
