[Closed] Fox X2 Recall

I had a call last Friday from Giant to say the '17 Reign Advanced I was interested in had been delayed well into the new year. Which comes with an X2. Probably 2+2=5.

Luckily I'd already gone for a different bike.

Haha was wondering how long before those started cropping up

Interesting point Deviant. My X2 was custom tuned by mojo for my Nicolai Geometron the bike Chris Porter designed and it came with 4 spacers fitted.

Picture clearly shows a failure of the can, starting by the stress raiser point near the machined valve housing/buldge. If you want to mitigate against this failure, put a few layers of decent gaffa tape around the can and then two nic ebig jubile clips, which will then just result in a safer release of air pressure, but prevent the can "unwrapping" and flying off........

If you even work to industrial pressure vessel standards, you'll know how weedy by comparison the thin, turned alluminium air can of most air shocks is. Considering that above 10bar, you would need to meet basic pressure vessel design standards for an industrial product, it's actually a little suprising on how bike air shocks can be made so weedy! However, because the compressed volume is small, the total energy release is pretty small too.

surely the best thing for fox to do would of been to put out a press release with the solution. not just dont ride the shock and wait for an announcement.

What makes you think they have a solution yet?

Congratulations, 99% of your post is absolute guff.

Was "i dont get it?!?!" the 1% ?

Well, the later 2017 models aren't in the recall. So worst case for Fox is to replace old with new. Whether they can manufacture fast enough is to be seen.

The best outcome for them would be to have a retro-fix. They do need to do something quick and seamless if they want to maintain customer trust, of they balls it up like Samsung, they're gonna lose a big chunk of market to Rockshox and the challenger companies.

Are the models with the climb switch as standard effected as all these are advertised as 2017 models???

I suspect the fix will be a combination of a new air can and the red limiter below, I think that's a new thing

I agree with maxtorque's theory. Split line is in the longitudinal direction which sees the highest stress. I would also suggest that people running higher pressures and more volume reducing spacers will have a greater likelihood of failure occurring since that combo will see the highest pressure rise through the shock stroke.

As for the rant about user tuning of shocks.....behave. Fully optimising shocks is far from easy, but there's plenty of guidance out there to make adjustments to suit ones preferences. So long as you follow the guidance and stay within limits (I.e. Don't fit millions of volume reducers) it's all good as far as I can tell.

Apprently the 2017 version has both the red limited above and a small allen bolt to keep the air can sleeve in place.

not the early 2017 ones - mine hasn't

OK, given all the above and the fact I don't have spacers and run it at about 190 psi and don't huck to flat from the roof of my house.....I shall ride mine till there is a replacement available.

Yeah - some bloke on pinkbike says he had one warrantied and got one with an Allen Bolt for the can - other 2017 cans don't have this.

BELIEVE NOONE

Just had a mail from Tribe in France. They have attached a press release from Fox with regard to this

must be the fix they've instigated following the faults on the 2016 and early 2017 models. I notice they've also dropped the max recommended psi down from 300 to 250

They have also cut back quite on the amount of spacers you can run. 63mm/2.5" stroke shocks are now 3 spacers max, iirc it was 5 max before.

Yeah, think mine has 4 in it, Mojo set it up originally, and there's a fifth in the box I was tempted to put in.

I'm running 1 and 180psi. Should be fine then.

They have also cut back quite on the amount of spacers you can run. 63mm/2.5" stroke shocks are now 3 spacers max, iirc it was 5 max before.

think it depends on if they are the old black rubber spacers or the orange plastic clip on ones. if the latter, mojo advised me you can run more and my 215x64 came with 5 fitted as standard with 7 being the maximum

2017 50 mm stroke. Three orange spacers fitted (of 4 max). [b]240 psi[/b]

Better not cycle near any children's faces.

Their chart shows different values for 2.5" and 63mm now, which is pretty baffling

^ it shows different amounts for a old shock measurements and a metric shocks, Fox USA never classed the 2.5" shock as a 63mm stroke shock. The 62.5mm shock will have a different dimensions to the similar sized 8.5x2.5 shock.

57.5, 60 and 62.5mm shocks all share the same chassis as the 65mm stroke shock, that's why those 3 can take more volume spacers as the stroke is restricted via a internal spacer. Just the same as a 7.275" eye to eye X2 uses the same chassis for 2" and 2.25" stroke but the 2" one can use more spacers.

One day the US might join the rest of the world and use the metric system.

Fox rear shocks just as rubbish as their forks SHOCKER!!!

Think pretty much every review said the 36 and X2 are the best. The only negative comments were on price.

Yes there is an issue, but they are sort of dealing with it and the cause has yet to be revealed. Could well be that only ones with too many spacers have failed

In the meantime RS have continued selling shoddy seatposts whose seals blow, and forks with CSU issues.

We demand top performance, low weight and perfect reliability, there will be issues with some products

hmm, might just drop a spacer or two out then to be on the safe side until there is some form of resolution to the problem.

Think pretty much every review said the 36 and X2 are the best

Having used a lot of the latest offerings for Fox and RS, I'd agree with that. The 36 is definitely stiffer than the Pike, it's a bit better overall on damping. It's not quite as plush on small bumps, but more controlled.

Fox and Mojo have always been great at sorting things out for me in the past, so I'm confident they'll sort out the X2 issues.

The X2 215x64 mojo sent me (unaltered) had 4 orange spacers in (and another 4 in the box - not enough space to physically fit that many in the shock).

Doesn't seem very consistent.

Anyone heard any news on this? Are they recalling them yet? Have they actually done anything for the hundreds of riders they've told to stop riding their bikes?

They'd better be ready to refund everyone that uses 4 or 5 spacers then I guess.

Bizarre to me that people would blame users for adding spacers (as long as they remain within spec). That's like having a dial that goes from 1-10, and if you set it to 10 it breaks, then saying "well obviously 10 is a big number so you shouldn't have used it. Volume tuning spacers are just inconvenient adjusters.

Does explain why I can't get through to mojo to order the 36 parts I want 😆

YT just emailed me telling me not to ride my Capra. They are waiting for further details regarding the recall.

I managed to survive the weekend racing on mine, and it didn't go bang.

Is there anyone that [b]doesn't[/b] use spacers? If everyone needs a smaller volume, what is the point of the large air can?

I was also not killed.

I don't use spacers in mine. Run it at 190 psi on a YT Capra and weigh (if I'm lucky and in the bathroom) 86kg.

I cant read the German email from YT, so will carry on till Mojo have some replacements.

190psi in mine, with 5 spacers, according to the manual, max is 5 and 300 psi....

hopefully more info will be forthcoming soon about what to do about it, but until then I am not going to put the float x that the bike came with back on, and will continue to ride it, as I have for the last 6mths.

I run 1 spacer as my frame is very progressive. I'm sure it will be fine and no one will die, just a bit off on their part. If the company I work for told our customers they were to stop using any boats our material went into, and stop building any yachts they were building and then just went quiet we'd probably never sell anything ever again and have millions to pay in damages. Just a bit annoying is all

Yeah, incredibly poor from Fox. I don't think they even have this on their own website, just a bunch of press releases to media.

I think some people need to calm down a little as well. Of course Fox have had to tell people to stop riding as soon as they were aware of the issue. Lets say they waited to announce this only when they had a solution in place but you're unable to ride because you have half an air can stuck in your thigh. You'd instantly be asking how long they'd known about the problem for.

In the grand scheme of things you've missed one weekend of riding so far. If you have to miss another, maybe deep clean the bike, service your forks or something. I'm sure Fox will have a fix for this as soon as possible.

Big air cans are good because you can always add spacers, if it's too small there's not much you can do.

It hasn't cost me any riding at all, some communication would be nice though.

I'll just leave these here.... 😉

When RS released the Debonair can for the Monarch shock it was perceived as "better" or an "upgrade" over a standard air can.

That's to do with the volume of the negative spring rather than overall volume though. The large volume negative spring was designed to improve suppleness/sensitivity of the initial stroke, Fox followed suit and it seems didn't take into account the higher pressures required.

Being able to custom tune volume is a good idea, with no downsides, what's not to like?

This

"if it's too small there's not much you can do."

Except buy an optional larger air can. Which is what used to happen. Now most of us ride oversized air cans reduced with spacers adding weight and bulk. With nearly everyone running air shocks it's not as if the bike manufacturers couldn't match their linkage curves to them.

Ideally make both options available, you can buy a CCDB with normal or big air can. Butif you can only have one it'd have to be the big one

Nothing to do with the fact my frame needs a large air can... 😆
