    RS Monarch RT3 losing air

    Anyone else experience this? I've only been on 10 rides with this shock and now it's losing air. I tightened the air valve, hopefully that will fix the problem.

    So far after tightening the valve core, it wasn't lost any air over night. Let's see what happens today on the trails.

    Mine used to bleed about 10psi when I rode it but it stopped after about 10 rides.

    I had to stop and put air in the shock about 4 times on a 4-hr ride today. I'll give it one more week to see if it stops.

    Take it off and stick it under water to see where it is leaking. If it is leaking from around the shaft seal you know you need to send it back, if it leaking form the valve core you can replace the valve core.

    I sprayed some soapy water on the shock to see if I could tell where the leak was coming from but no bubbles. I'll have to spray the valve core to see that's where the leak is coming from. For some reason it slipped mind to do this earlier.

    I got my RT3 from Titus and acutally had to replace the valve. It was immediately leaking air. Not a big deal. My mechanic had an extra one. But I have noticed that it has lost some air over time. I have put about 100 miles on the bike and shock and I think I need to adjust the pressure again. Have noticed it is compressing more initially with me on the bike.

    My mind is boggled

    So after riding my El G this weekend my shock is still leaking. When I left the sag was set at 20% and when I returned it was down to 30%. I removed the shock and placed it in water, I thought I saw some bubbles coming from around the dust wiper but the more I dunked it, the less I think it's coming from there. There are no bubbles coming from the shock while under water. Plus, the shock held air all throughout the week with it sitting in my garage. It seems like it only looses air when it cycles. I guess I'll wait and see what Titus will do.

    Keep me informed of what you find out. When did you order your RT3? I seem to be having some of the same issues as you are.

    I've only been on about 10 rides with the EL G. It seems several people have had issues with this shock. Rick from Titus said he would take care of it last week, however, he was in the UK. I checked with Push to see if they would tune it, but they said they are about 1-2 months away from starting to service the monarchs.

    Sending it back

    Heard from Rick at Titus. He wants me to send the shock back so it can be warrantied by SRAM. Guess I am done riding for the year since it getting cooler and cooler in Northern Arizona.

    With the shock off of the bike, put about 250-260psi in it and place it in a bucket of water. No soap. Leave the air valve cap off as well. If you're leaking air, that's the best way to tell where.
    Maintain internal heights.

    Thanks, but I have already shipped it out. I have the shock up to 240 and I didn't see anything. It's driving me crazy!!

    I had a Monarch R (stock on Salsa Spearfish) that just recently did this same thing. All of the sudden started loosing air while riding after ~6hrs. It wouldn't leak while stored or submerged. LBS called SRAM and had me a new RT3 the next day.

    Nice. My shox finally made it to Portland today, so my riding season will be done for the year if I don't get a new one or mine fixed soon.

    Just arrived

    Rock Shox sent me a new shock. It took a few week to get this sorted out but Titus did come through. Lucky for me the snow has not come yet, so I'll be able to get out and ride tomorrow. I'm crossing my fingers that this one won't leak.

    Did yours have the "swivel valve" by chance? The schrader valve swivels out to put air in? I guess they have had serious issues with this.

    It's the shock that Titus sells on the their website. There's no information about a "swivel valve."

    I hope you get enough rides in before winter jdc to see if the shox is
    okay. I got the same shox from Titus (8.5x2.5) about 2 months ago,
    but have it on my 06 SuperMoto. I'll keep a closer eye on it now to see if it leaks.
    Craigstr the shock has a fixed valve stem on it.

    Only have a few rides on my new EG and I now have the same problem with my shock. I had to air it up half way through my ride yesterday. I will try submerging in water tonight to see if there are any obvious leaks.

    I think I might pickup a backup shock, as I can't really afford to be without the bike for weeks...summers are short as it is.

    I did pick up a backup shock (cane creek cloud nine). My shock is still at SRAM I am guessing. Has been out of my hands for over a month now. I would suggest getting a backup for the interim.

    It took over a month to get mine back, but RS did send me a new shock. So far no problems, but I've only been on a few rides since the snow has finally melted.

    How is the CC cloud 9?

    Yes - this is the second time mine has been back. I think they just replaced the internals the first time, but it came back doing the same thing. The CC Cloud Nine is actually really nice. I think it is plusher than the RT3. There is definitely more pedal bob to it, but it is not terrible. Small bump compliance is really nice. And it being an air shock, it is super reliable. I just check the pressure every time I go out. No more filling up every ride. A good back up for sure. But I like the climbing characteristics of the RT3 a little better.

    Is there a trick to removing the air can? Mine seems to be welded on! I've destroyed my strap wrench trying to get it off.

    My RT3 started leaking air from the base of the valve stem. For those of you that had the same problem, did Rockshox warranty it? The shock is less than a year old.

    Thanks!

    There were no visible leaks on mine. Only leaked when cycled. I am not sure but I think there is a one year warranty on the shock. So if you are going to get it in, I would hurry. They don't deal directly with consumers, so you will have to go through Titus or your LBS.

    Sent mine back to RS and it took almost a month to get it back. Seems to be ok now. Was loosing air throughout the stroke like some others.

    I just got my shock back from Titus/Rock Shox this week. It took over 4 months! And to top it off, they sent it back without any decals on it. Not a single one left...weird.

    had similar problem, was going to send back, but first tried lubing seals (flouropolymer stuff, probably float fluid would work too, but apparently RS are picky about what you to do it). no more leaks since. was losing about 1/3 the pressure in a long ride before!

    I have the same issue and this is what Titus told me:

    You can either take it in to your local retailer and have them send it in for warranty/service or email SRAM for their procedures on handling direct warranty issues. Either of these would be the fastest way to deal with the problem. We can send it in on your behalf as well but we are not set up for direct consumer service so it could take a bit longer.
    I'm going to try to send it to Rockshox direct or Titus if that doesn't work. I didn't buy the bike from the LBS so it would be weird to get them to do all of the warranty leg work.

    EDIT - spoke to Titus today and they are sending it into SRAM for me

    In my experience, this is a bandaide fix. The seals don't get properly lubed from the factory. Once they are damaged and start to leak, adding oil will only work for ~10hrs. After I put in new piston/can seals properly lubed, I have not had a problem after over 100hrs with the recommended can service intervals. YMMV.

    If you can change the seals yourself, don't even mess with sending it to RS. You can buy the x-ring for the piston and can individually for pennies.

    I tried to take mine aprt to re-lube or do a seal replacement and I couldn't get the can to budge. Tried a strap wrench, warming it up first and still couldn't get the thing to spin off.

    Same here. No way that thing was coming off. Broke a strap wrench trying.

    yes i also tried to undo can before just applying lube externally. will probably have to return at some point then as couldn't do it. it's been fine for weeks now, no more air lost. but at some point obviously it'll need a service.

    what i don't understand is why outer sleeve just spins around, but doesn't leak. is this correct?

    Asked myself the same question before... Apparently most air shock work the same way, its the rubber o-ring at the end keeping the air in.
    That's why it pays to have it lubricated frequently and not be dried out and hardened up.

    The tiniest nick or an uneven ring is often the cause for leaks... depending on these irregularities-- can be a fast or slow leak.

    BTW-- the Monarch I feel just isnt the right shock for the EG unless you like the bike stiff for say race and generally a more xc setup.

    Having one now and have given all the time its needed to break in. For a more compliant rear, even the old crappy RP23 (pre boost valve models) with a biy of DIY shimming on the air can is a lot better.

    odd, my small can RP2 (other bike) doesn't have two parts to the can. just seals above thread and on stanchion where you'd expect.

    for me, the Monarch is a good choice i think, i need it firm because of my... ahem low bb. and i ride it for xc anyway

    ah excuse me, I tend to use the term seals and o-ring interchangeably on these parts...
    yup the seals are what I meant.

    Ive made a complete rebuild myself without changing any o-rings, just greased everything. No more air loss now even when its snowy outdoors.

    Thanks guys. An update I mine. I took my shock into the lbs and the guy took the valve stem out and the o ring was all mangled up. So he just replaced that and it's good to go. Thanks!

    Glad i found this. I took off the outer air sleeve to adjust the air volume. When l went to use it the shock it lost tons of air and rather quickly l might add. Im thinking i need to tighten the shock up meaning it might of came loose when l was messing around with the outer sleeve.
    Do really want to dunk my shock in water? If l have a fast leak wouldn't the water have a greater chance of killing the shock?
    We'll see

    I'm curious to see if they are any better than these old posts. I just received mine and air is leaking from the valve. I removed the cap with a little "pop" which I thought, no big deal. But then I did it 3 days in a row, each time with a little "pop". Maybe the cap will hold it??? But the big problem seem to be the ram seals anyway.
    It will be a week before I'm riding it, will see how it goes.

    if its leaking from valve just change valve core, it's standard schrader right?

    mine after working perfectly for a couple of months, is leaking again when cycled. i think it's from the end of the can (negative air chamber) when removing can i can see dirt there, i just don't think the seals are good enough.

    my Q is: is the air can sealing any better on higher end SRAM shocks like the RC3 plus? or should i go to coil or even.. fox ?

    edit: looking at service manual, looks like air cans are identical between RT3 and RC3, so i don't think i could trust either. will look at coils.

    had an interesting chat with a suspension specialist in uk today.. seems there may be a known problem with the RT3 (and presumably the RC3, but apparently not the vivid air?) something to do with the anodising on the air can? anyway they fill with dirt and leak air unless you service them loads.
    now wishing i had gone straight to coil or CCDB or something! i really like the Monarch action when it works though, but SRAM were not helpful when i spoke to them, they charge loads and kind of evade the question. so a replacement air can and damper may cure this i don't know, do i want to risk spending more on Monarch?

    i'm thinking about Vivid Coil, anyone got anything good or bad to say about that? it's still SRAM, but i can get one (2013) for same price as Van RC. maybe will regret, at least no air to leak! wrong thread sorry maybe answer here if you can

    My RT3 started working a lot smoother after awhile...
    Recently it keeps losing ~10-15 psi of air after every ride, or within a few days if the bike is not ridden.

    Gonna just watch awhile more and see if anything else develops from there...
    Will open it up and see what's wrong after my new shock arrives.

    yep, take the air can off, i bet you'll see tons of dirt around and inside the end (damper shaft to air can) seal. clean it out and lube with Fox Float or something similar, and if it hasn't already done too much damage to the damper/can/seals i bet your shock will be fine again for a while. if you ride lots, you need to do this maybe monthly?
    btw if you need new seals you maybe SOL they're sold out in uk now apparently, maybe US has some.

    btw i had a Fox RP2 for years never had this problem. RS sealing isn't fit for purpose imho. what SRAM should do imho, is improve the design and offer free upgraded air cans to everyone affected. fat chance.

    edit: mine never lost air if not ridden, possibly not same issue. still there seem to be problems with sealing on some/all of these shocks..

    Thx.. planning to do just that. Yea-- while I have things I don't like about the RP2, holding air is definitely something it does well.

    Seals and kits are not a problem for me to get.

    Strange thing on mine is that the said amount is all it loses and afterwards it stays right there without going any softer... hmmm

    Anyway I have a Vector HLR arriving anytime now and was talking to the factory on how I wanted to match it with the front fork.. so let's see what they have modded with the shims to let the front and rear match up. My Monarch might just end up being something to tinker with on the workbench.

    the losing a fixed amount thing sounds familiar, i was always down from 125 to 100psi after a long ride. i think related to losing air from the negative chamber? not sure.

    i've also ordered a new shock (coil vivid, for some reason).
    it's a shame as the RT3 in action is a much much better shock than the RP2/RP32 imho. (where the RP2 just wallows, the RT3 gets better and better the faster you go). if only they were more reliable :/

    if i'd known this myself before learning the hard way i would have cleaned and lubed it much more. if you ignore it, the stanchion (damper) will get damaged by that dirt.

    I fixed mine. Long story short i was unscrewing my entire shock as if i were taking it apart. I simply screwed it tight again.

    yeah um don't do that

    it amazes me the large air can seals even work, there's not much holding it on. just two thin orings, and the big one you see just stops the outer sleeve sliding off.
