Making shocks bit stiffer.

[vrooom]

my fork are Marzocchi Dirt Jam Comp, 100mm travel. I would like to make it bit stiffer. the adjustable on top of the fork are at max level.

Are they air or coil?

If air... pump more air

If coil... you can either get a shop (or do it yourself) to increase the thickness of the oil or replace the springs with heavier versions.

No idea if they are air or coil.... i'll have to find out.

Ok they are coil. I could do it myself. what oil to use ?

Dunno tbh.

You need to find out what grade of oil they have in as standard, then go to a thicker oil. As for sourcing oil, you probably need go to a bike shop and buy proper hydraulic fork oil. Are you sure the oil isnt just used for lubrication though, as opposed to actual damping?

According to this Marzocchi fork manual, your fork is an elastomer fork with a coil spring. It also gives a troubleshooting table for when the fork is too soft/hard etc.

Marzocchi generally use DOT oil, the same as in motorbike forks. It's readily obtainable, just check with a reputable bike shop which DOT it is (I'm afraid I can't remember and don't want to give the wrong advice).

The Marzocchi website will give you all information regarding set up of the fork, however if it is a coil spring that's too soft, then it may be that you will have to replace this for a stiffer version. There is a highly recommended fork servicing company called TF Tuned Shox which wil do all of this work for you.

With an elastomer fork though, its going to cost more to pay someone to rebuild it (~£70) than it would to replace it with something superior off ebay etc.
