The Sexiest AM/FR/Enduro Hardtail Thread (Please read the opening post) If it's really low, that could be your problem. If that's what you're running, I'd expect that it's probably fine.Ĭheck the pressure on the Boost chamber with a shock pump. It's seen ~20-50 days in the whistler bike park per season since about 2013 and I'm ashamed to say I've never rebuilt it.

I've never had to take it in for service since the boost chamber takes a regular shock pump. That being said, I run one of the Fox DHX 5.0 that you showed in your video. This could also effect your rebound response. That will make your shock feel bad and you'll want to take it in for service if you can't do it yourself. I've been told that shocks lose pressure in the boost chamber the way air in a tube loses air over a year even without being ridden. Rockshox Monarch also has a valve on it's boost chamber, but it hides the valve under a cap that's flush with the surface. Just because you don't see that on your shock doesn't mean it's not pressurized. In the video of the coil Fox DHX 5.0 you posted you can see the valve for the boost chamber. Coil shocks still have air pressure in them. Most new shocks require you to have nitrogen to rebuild your shock as well, and it's very dangerous to dissemble it if you do so while it still has pressure in any part of the system. You do need to dissemble the shock to bleed the damper. would not recommend if you dont have the confidence or mechanical knowledge of how the thing works. if you want to service the internals of your shock, you will need special tools as well. If you want to bleed the damper of your fork it most certainly requires special tools and taking it apart.

if you adjust the rebound, you change the ease of oil flow, which will change the sound it makes. close the rebound = smaller hole for oil to flow through = slower rebound. the more open the hole is = oil can move through it faster = faster rebound. If you adjust the rebound dial, it opens and closes the hole that the oil flows through.

The noise is literally the sound of oil moving through a tiny hole. Is bleeding the damper easy to do ? or require taken it apart Maybe just through lack of use some of the oil ? or air got trapped in the wrong place ? That may be it !!, because i heard the air squish sound before (It doesn't seem to be making that noise ever since messing with the rebound dial).
