[#9242073]

Had my new bike delivered a couple of weeks ago, I've had a couple of short rides on it so far and all seems well. But, I've put a fatter cassette and single ring on and when I let the air out of the shock to check the chain length the rear tyre hit the set tube.

I've ridden it again fairly hard since to see if it hits during normal riding and it doesn't look like it has, but it was only at cannock so there's nothing to say it wont happen somewhere proper or if I take it over stile cop.

Has anyone heard anything about this from anywhere else? Or is it just me?

Sounds dodgy certainly. I wouldnt think that should happen on a full suspension bike, as its surely dangerous if you bottom out the suspension.

Come on guys, any one else own or know some one who does that can test theirs?

Save up and buy an Evil, at least at that money you know that sort of thing wont be a problem.

Joking apart that thread was what made me check.

At least I can be safe in the knowledge that I've got half decent parts to swap onto another frame if this one dies. And it didn't cost the earth.

I've pinged an email to go outdoors customer services, if it's not a fault I'm surprised I'm the first person to post about it on the interwebs.

thats a bit shady.
I set my patriot 66 up in "slack" mode and it snagged the seat tube (i probably had the slider in the wrong place). All it did was lock the rear wheel momentarily, which pitches the weight forward a shade and "unlocks" it.
wouldn't want to plan on it though

Whats the shock? you could add a bottom out bumper into the shock, or get a shock with a shorter stroke length if your worried about it?

if you want to keep the bike i would "update" the internal bumper.
Perhaps cut a big washer out of an old tyre or a couple of out of inner tubes. Make sure they are super clean before they go in the shock!

you could also put in some bottomless tokens (or a lump of grease) which will take up air space, causing the shock curve to ramp up quicker, which will reduce the likelihood of blowing through the travel while maintaining sensitivity.

It's a Monarch R shock, so volume reducers are an option I think. Last third of the travel seems to ramp up nicely anyway, but I've only put about 15 miles on it so far. I'll see what go outdoors say, and in the meantime I'll try and give it some proper stick and see what happens.

I don't really want to swap it, I've spent ages sorting it out and it's almost finished, just need to seal the front tyre properly.

in all honesty, its a lot of bike for the money and the shock is a pretty average length. Worst comes to worst just pick up a new frame from on-one or Crc.

Ive never cycled my five29 through its travel. Here is an album of bikes "G'd out", smashed into a compression to blow through the travel.
Interesting!

Uh oh, there's rubbing after ride no 3, no mud, less than 30% sag 😥

Going down the online route at the mo because I didn't get it from a shop, got a feeling they're fobbing me off though so a phone call to wolvo store will be coming soon.

What a palaver.

Managed to get an answer from Go Outdoors on twitter, they've acknowledged it's not right and are sorting me a fresh frame by the looks of it.

Thank god for social media, customer services weren't interested, suggested more air in the shock 🙄

Not sure I understand really and I can't see the problem from the photo?

Interested because I've had my medium sized bossnut for a few weeks now and taken it round the freeminers and verderers trails a few times in the Forest Of Dean with no noticeable issues, other than my lack of talent or speed that is!

Poor design I guess. My old commencal am1 meta 29 also rubbed something terrible.

@baldiebenty - if you can, let the air out of the shock and see how much gap there is between the tyre and the frame. There should be one, but on mine the tyre goes all the way to the frame and is rubbing the paint off on landings.

It's worth checking just in case it was a bad batch, eventually it could wear the metal away and the frame will crack.

ok, sounds like it's worth checking. I'll take a look tonight. Especially as I'm planning to take it out tomorrow night again.

A couple of different angles

ah right, I wasn't sure I could see any marks on the first photo. That definitely doesn't look right.

I haven't bottomed out the shock yet as straight out the box it seems to have been bang on for me, except tweaking the rebound. I'll check with the air out later this evening.

Is it possible the shock is either too short or the stroke length is too long?

It wouldn't be the first frame that has a rear tyre as a bump stop, Evil and Santa Cruz have had issues with it.

Hopefully a new frame will sort it, but I'd surprised if it's a manufacturing fault and not a design fault unless it's a shock issue and not a frame issue.

My 224 did that. Hemlock did it too but only because I'd filled it with slackness, it didn't do it as standard. Neither was ever a problem but it's not ideal, not sure what I'd do in your position if it wasn't causing an issue but it's reasonable to take it further for sure

They say they've not had any reports of this before, and looking online they appear to be telling the truth, I'm taking it in to the store on Friday for them to have a look, it's unlikely they'll have another in store to compare it too.

If it can be swapped for one that doesn't rub I'll be happy as the bike rides mint, customer services suggested a smaller tyre but I don't want to fork out my own money after 3 rides, and having a quick look around this morning there's not a huge choice of 650b tyres under 2.2.

MBR have just tweeted to say they're going to have a nose at their test bike too

We shall see what happens.

That's just silly, if it can't work with it's OE tyres it's wrong - and 2.2 is pretty small, even for a rear.

Glad it's not just me that thought that. I'd be knackered if I rode anywhere muddy with the tyre it came with on the back.

Hmmm, must check mine. I've only had out once so far and was really happy with it...hoping this isn't a general issue.

The cynic in me wonders if they "adapted" a 26er frame to 650b and neglected to extend the rear triangle because it looked like it was fine...

I hope not because I'm really happy with it.

I thought the medium was a bit too big at first (I'm 5'10) but fitting a reverb brought the seat forward a touch more than the original post and I've enjoyed every ride on it so far, although in fairness it did replace a "slightly" worn out carrera hardtail 😳

@rossburton - I did wonder that myself. I wonder if they'd started developing a 26er and then fashions changed.

That said, apparently mine is the first one they've heard of. I'm still waiting on MBRs check.

Other than this it's proper good, went out yesterday morning to tweak the rebound settings and set a few Strava PBs on sections I've ridden 100s of times.

I'd still recommend the bike 100%, go outdoors so far have been not as good as decathlon to deal with but that's the risk you take not going to a good LBS. If you have one.

Ok, Checked and damn it's close but no contact with the frame having dropped all the air out of the shock and fully compressed it.

Hopefully the pics will work.

If it's that close in static conditions, work stand etc, then may rub when riding.....

Did you push it down once you'd let the air out? Mine settles with about 2-3mm or stroke left and there's no rub then, but if I lean on it...

Tried letting the air out of the tyre tonight too to see how much further it will go. It's only a gnats nadger away from making it, but there we are. Going to the store on Friday, I'll get them to let the air out of the shock on one of the stock ones and see what happens, spoke to the main bike guy on the phone today, it didn't fill me confidence to be honest, but the person on Twitter says they would be able to sort something by post if it comes to it.

If the one in the shop is fine, I might just leave it and stick a couple of extra psi in and just ride it. Do they do a 195x50 shock 😆

Yep, let the air out and then pushed it full down, gave it a few good bounces too to see if frame flex would make it touch, didn't that I could see and as it is I'm not sure I'll ever use that much shock travel, I'm gonna pump her back up and just ride the little beauty 🙂

Sweet, then I shall see what happens at the shop I can't wait to give the thing some stick either, same thing happened when I bought a rock rider from decathlon i had to get the forks replaced on then within a week too 😡 I have no luck with cheap full sussers.

Took the bike in yesterday, very pleased that I was welcomed into the store by I assume the manager who knew all about the issue and was apologetic that the replacement frame hadn't come in yet. May well have to wait until next weekend to get it back but the weather is crap so not particularly bothered.

We let the air out of the shock on the display model and there was a good 5-10mm between the tyre and frame.

Confidence is high.

Update -

Replacement frame has the same problem. They think it's the whole batch of 19"s

Gutted, they're going to give me one back to ride while they investigate, Mike Sanderson is involved now which is nice.

Hopefully will be able to get out on it this weekend, weather looks reasonable for a change.

What Mountain Bike have one with the same issue. They suggest running a smaller tyre which seems an odd response coming from a mag.

1) Send it back.
2) Go to a good LBS.
3) Buy a bike from a proper bike company.

Yeah its no good if it's not from a 'proper' bike company , which would be why MBR (other bike mags are available) voted it their 'bike of the year 2015'

OP glad that Go Outdoors are trying to sort things out for you ,if you ever decide to get something a bit flashier please don't become a bike snob!
