Hey folks I just got a Marzocchi Bomber CR and it's been working very well for me, but this rear shock has started not being as responsive just a few months from buying it. I don't know if it needs a rebuild already or what, but I'm not wildly happyMadder

I suggest checking your pivot bearings to see if they're toast before the rebuild.

Hard to guess as to what could be the issue with little information given. If you can be specific as to what you feel is wrong with the bike that would help us alot.
ex. is it rebounding too slow? is it feeling sticky on compression and rebound, or just one?

Do you live in an area where temperature varies a lot? A few months ago could have been 30 degrees different from now, and oil viscosity could be the difference you feel.

It could also be you have a bike with a Y-yoke and that suspension linkage can break Bomber CRs quickly.

It feels sticky on compression and at the beginning of compression it feels extra sticky for a tiny bit. The temperature here in Washington was about 15, but now we have highs of 60.

I don't know a thing about the bearrings, and haven't done anything since I got the bike used a year and a half ago.

Does anyone know where I can find service / rebuild info for this shock?

Everything I can find just refers to a fox shock from a few years back that this was based on.

YouTube video? Instructions with pics? Anything really other than just the exploded view.

Cheers

I swear it's deliberately MIA from everywhere...... how can not 1 person craving YouTube fame not have posted a video or something.

Problem is a rebuild is about 60% the cost of new so I'm willing to have a try or just buy a new one and sell this one to someone who can service it.

You don't necessarily have to change out the bearings but at least removing the hardware and inspect under the bearing seal. If they are rough, clean em out with a nice bike friendly degreaser and repack with Green Grease you can get at the store or Walmart.

Dental pick to get the seals off
Clean until they spin smooth and let dry.
Pack with Green grease, spin to get it worked in all the way, put the seal back in.

I had a '15 operator that looked perfect, took the shock off and felt quite a bit of friction. Previous owner greased the bearings with white lithium...that stuff packs out and gets dry. Cleaned and greased, smooth as butter now.

A good idea to do all your bearings, headset, hubs, and pivots. Washington winter riding will kill poorly greased bearings in a few rides.

If it is the shock and it's new, look into warranty. If it's used contact Butter Suspension or the shock howse

Rebuilding a bomber CR isn't something you can do in the garage with hand tools, you need a nitrogen charge, proper tools for disassembly, etc. It's not as simple as air can seals in an air shock, it's full tear down, which is why you should really do your bearings first. If you cant do your bearings there's no chance you could service the shock. Heck I rebuild forks for hobby and I wouldn't touch a damper rebuild in an air or coil shock.
