An actual relevant thread from me - I know, I can't believe it either.

I bought a DHX air in May 07 for the RFX as it was on closeout (the thread of joy I posted at the time is here http://forums.mtbr.com/showthread.php?t=298239 - I was very polite then:D ).

I'd be surprised if the shock has 100 miles on it (really) but yesterday I dug the bike out to give it a tune up as I'm expecting to ride it more this year after some time spent overseas.

Anyway, a quick once-over and the RFX was in fine fettle. Checked the shock pressure and put a bit more in as I have eaten a few pies since I last rode. Got on the bike and the shock immediately blew through it's travel and the i2i is now 7in as opposed to the DHXc which came with the frame at 7.5in.

So....either it was always 7in and I got the wrong DHXa but just never checked when I put it on originally (which is quite possible as I'm somewhat dumb but I got the shock from people who would know the correct i2i for an 06 RFX...) or it has stuck part way through its travel. Either way it isn't holding pressure which I think is pretty poor for a shock that's hardly been used (albeit in storage for quite a while).

I don't expect the shock to be warrantied as it is over 2.5 years old and was on blowout when I got it, but what are my likely options? Anything I can do myself to un-stick it? I'm in the UK if that makes any difference.

Thank you kindly for your assistance in this matter - I know I should know more about this stuff.

Cheers,

TB

do you have any use for a cool looking paperweight?

Behold the first Pro-Core (TM) Review of 2010

Yes, but then I'd have to sell the Mojo frame that's doing the job at the moment.
At least the DHX a can be repaired and even modified to accommodate your weight (see DGC mod). TA apparently loves his DHX a;)

That said, in the business of paperweights, the Mojo is a perfect example of Form/Function and really is not suitable as a true AM Paperweight. I think it is better suited as a Nutcracker. The Lopez link resolved some issues they were having with Kola nuts.

Being "Pro-Core (TM)" I would certainly defer to "broken" 5spots as a "heavyweight" alternative. :thumbsup:

Yes, it is rubbish. Sell it quick!

I just e-bayed one off my wife's 5spot, got $182.50 for it :thumbsup:

Some folks swear by them, PUSH won't touch them, hmm, wonder why?

DHX airs and and any air shock generaly is as poor a performer as Liverpool in the Champions League on your iteration of RFX based on my experience. If you are looking to shave weight off the bike look at the tyres.

PS I miss cornish pasties and pies!

Release all the air. Pull the shock off the bike. Pull the air sleeve and do the recommended air sleeve maintenance (a total moron can do this, so you're probably pretty close to being OK with it). Add a plastic shim per DGC's thread to give some mid-stroke support. Reassemble. The DHX-A is not inherently a bad shock despite many bad reviews. The shim will greatly improve it. I doubt you have a "stuck down" issue since you would see much less eye to eye than 7". If they gave you a 7" eye to eye shock, then you've been had.

Can't - someone will do a google search and find this thread:D

I probably will sell it, but I'll need to fix it first.

Oooh you b1tch!:eekster: You mean "won five times", etc.?:D We have decided to concentrate on the Europa league this year thank you very much.

I see your mob finally won a match this season - great choice of manager.

I'm looking at the tyres (and thanks for spelling that correctly) but the weight isn't coming off.....do I need to touch them or something?

Jeebus - five years a member and I still can't multi-quote. I reckon I'd have about 100 posts if I could use the interweb correctly.

Thank you for your kind words in the quote above - don't suppose you have a link to "the recommended air sleeve maintenance"?

The Fox website has a video of the procedure - in a nutshell - you deflate the shock, remove it from bike, clamp eyelet in a soft jaw vice, unscrew the main shock air can and pull off, clean, check o-rings, add Fox Float fluid, re-install. You can unscrew the air can "whilst" (please note fruity use of UK lexicon) the shock is still on the bike if you lack a vice. Add the shim before reinstalling the can. Actually, you should just sell it. The DHX-A will suffer terribly under your massive lard load and the 3 to 1 leverage ratio on the out-dated non-DW link RFX will also cause pain.

Thank you Grandfather. I can tell you want it, how much are you offering?

I was worried for a while but we have only lost once in forever just too many draws - I honestly wouldn't be surprised to see a play off run. Keane got the mackems out of the championship so no reason why he cant do it for us. I think Benitez is much more liely for the sack than Keane.

PS mtn biking is great.

I disagree, further evidenced by the fact that Push won't even work on it (pretty big detracter right there). How many companies spec it, just to have the riders say it blows through the travel? You might reduce bottoming-out with a shim, but it's still going to have a flat mid-stroke as all air-shocks do. If the shock could be revalved you might be able to do something with it, but it's not possible. How many years has fox had to fix this? On 95% of the bike's it's speced on, the DHX Air is a turd.

I think the DHX air is speced, and sells due to the same reasons the old Jr T and Z4s sold. Push on them in a shop or ride them off a curb at slow speed and they are amazingly plush. The faster you go (unlikely to be encountered during a short test ride) the worse they perform. Doesn't really matter though if it sells and makes money.

Don;t go mis quoting me :nono:

I doubt I ever said I loved it, that said the mod definitely improved the mod stroke and allowed me to run a little less pressure to have better initial stroke! Its ok and not as bad as everyone makes out ya could ;ive with it setup with this mod and tuned properly.

But love it no, I am and always will be a coil man :thumbsup:

If you haven't been spoiled with a real coil on the RFX then I doubt you'd mind if you do this mod and ride it especially if ya need a crutch in light weight to help you uphills etc

TB you you'd try it out search DGC shock mod thread!

But being a heavy arse you'd def suit a coil better :D :thumbsup:

measure ya i2i 7.5 stroke 2.0 or 57mm!

Go hard big guy

Thanks TA. Snowed in here so I may take the large hammer to it tomorrow and see how it goes...:D

Dibbs, there's a coil on it now, but it's a DHX coil....I just can't ride it at the moment due to the weather. I do agree that they look better and more manly.

My DHX-A circa 2007 had the "stuck down" issue and wouldn't hold air. It only lost about a half inch off the stroke like yours. Fox ended up fixing it for me under warranty.

It still sucked afterwards but at least I was getting full travel and it held air. You may have that stuck down issue which I believe was due to oil leaking into an area where it wasn't supposed to. It was a common problem on the early DHX-As. Again, it really did suck even when fixed.
