Only just had chance to check my replacement frame. In the end they ended up giving me the "new" version of the frame because of how long the replacement was taking to arrive. The replacement has the exact same problem which suggests it's more than just a few bikes that have been affected as go outdoors claim.
Has anybody else got a replacement that's fixed the issue yet?
New version as in the 2017 frame?
No it's not the new frame design that was posted by sam1newbold. I was told the replacement I have been given is the same frame design as it has always been apart from a new lick of paint seen [url= https://twitter.com/andrewmpeace/status/785442566565134368 ]here.[/url]
Still nothing here. Should have been here mid last week, will drop Mike an email tomorrow. Not too fussed at the moment, as I've been too tired/I'll/busy to go out on the MTB anyway but still.
Not bothered about getting a refund, there's nothing better I could get instead, good things come to those who wait I hope, so I'm expecting something epic.
Hi Prawny
Anything to report this week?
Sam
Just noticed this posted up on Facebook:

Be careful if you decided to ride big drops with the shock bottoming out.
Hi Prawny, my replacement frame has arrived in the shop and should be swapped over this week, hopefully I won't have the same problem with this one.
Yep mine too, dropped it into the store yesterday. Fingers crossed this one will be fine, not sure I like the new colour as much, but I wasn't massively fussed on the old one so no great loss.
That pic above is a terrible photoshop job, you can see where the front wheel has been cloned over. Nice try though.
I don't think it's a photoshop, here are more photos of it.

Hope you get it sorted. They fit the new colour of the frame for me and it had the same problem.
Oh yeah, on closer inspection it's a fern that looks like cropping. I stand corrected.
That's well borked, wonder how hard they were pushing it.
Eeek
HI Guys,
I've only just been made aware of this feed:
The QC issue is a result of the front shock mount being welded 1 -1.5mm further forward (towards the head tube) than it should, we’ve had around 15 bikes returned from thousands sold. The issue has been rectified at the factory and anything from here on in will not be affected. The fixes I have are: 1.) I have a small number of replacement frames, but some of these were damaged in transit so I’m waiting for some more. 2.) I have offset bushes, these will move the rear shock back to the correct position and is an easy fix.
stores are aware of the issue and will be able to help you.
once again sorry for this, and as i've said it really is a small batch issue and the buzz is just that and will not stop you mid ride etc.
Best regards,
Mike
2.) I have offset bushes, these will move the rear shock back to the correct position and is an easy fix.
What stops the offset bush naturally rotating in the frame? (And making the problem far worse)
What does an offset bush look like before and in situ?
@ Sir HC The suspension forces keep the bushing rotated in the correct position. The shock is always under compression when in use which keeps it in position. It's a non-issue 🙂
@buckster we'll get you these images, but this has been checked and it fixes the issue 100%
Ref: Photos a few posts above.
Those were taken last Saturday at Cann Woods near Plymouth. They're completely legit - I was following the rider (a friendly chap I'd just met) down one of the smaller lines when the bike failed on landing a ~2.5' drop into a mild downslope. The owner has been in touch with the local Go Outdoors store and initial impressions seem to be that they're sorting him out.
Not a great bit of design work, unfortunately. The shock seems to have bottomed out and extended the wrong way, if you will, forcing it further into the downtube. At the same time, the rear wheel has somehow flexed around the saddle and well and truly wedged itself to one side of the seat tube.
Hope you guys get sorted soon. Good to see a response from Calibre Bikes.
As my rear tyre touched the frame when the rear shock bottomed out, I contacted the Cardiff store; who informed me its a 1 in 15 medium frames problem. I dropped my bike off to them yesterday morning and picked it up yesterday evening with a brand new 2017 frame on it. Cant fault their service tbh. I will check the frame doesn't touch the rear tyre this evening and give it a blast on the weekend, but I expect the problem will be sorted now :o)
@ Sir HC The suspension forces keep the bushing rotated in the correct position. The shock is always under compression when in use which keeps it in position. It's a non-issue
The force on the bushing will actually cause it to flip round in use and given that this can cause failure which results in the tyre contacting the seattube, I'd be wary of relying on clamping forces alone to stop the bushing rotating, it should be mechanically keyed in place (Scott/Trek/Etc, use a flip chip and don't use a simple offset bushing, as they know it will rotate in use)
The original use for offset shock bushings was to slacken the headangle, the offset holes being positioned to effectively lengthen the shock. The forces being fed through the offset bushings would keep them position correctly.
Unfortunately, Go Outdoors rang yesterday to say that the replacement frame has a big paint chip on the head tube so they will need to order a new one. I guess that was what Mikes post was referring too. Hopefully I won't have to wait too long for the replacement and hopefully it will be a 2017 frame as it looks to be stiffer with bigger tyre clearance especially as I'd like to fit a bigger mud tyre for the gloopy months.
Are there any photos of the 2017 production models?
I'l post a photo tomorrow. The frame is supposed to be 10mm longer with bigger tyre clearance.
This is quite revealing, looks good to me
http://factoryjackson.com/2016/10/21/calibre-bossnut-2017-prototype-bike-check/
That's the second collapsed Bossnut I have seen now. No way would i trust one if it wont even survive small 2 1/2 foot drops. It wouldn't last 5 minutes round here. I have an anthem that takes more abuse than that and that's an xc bike. The pictures on the gooutdoors quite clearly show the bike being used on a jump but it doesn't sound like it can actually cope with it. I think I would be getting my money back and buying something more suitable.
I see a few people raising issues with the fork yoke clearance as well, is that just a thing with the sektor forks?
I'd been tempted to get the bossnut on a cycle to work, but these recent issue are making me think ...not.
Are there any further photos from the other side of that failure.
It looks like a failure at the seat tube where the linkages attach from the suspension arm. Judging from the shock still being attached to the arm itself. I can't see the seat tube itself though from the angles given.
Interested because I'm getting to the stage where I'm hitting drops not much smaller than that and trying harder on the jumps, first time at 417 Project @ Gloucester last Sunday etc. so I'd rather this didn't happen to mine 😮
Lets not forget this is a 130mm travel bike i.e trail bike, not an enduro 160mm or downhill 200mm or freeride bike. I have done little 2-4ft jumps and drops on the Bossnut with the faulty frame and the bike was fine. A mate of mine recently cracked a Lapierre Zesty frame....
I use my 160mm Giant Reign for gnarlier trails and bigger features. If ya looking to hit DH and freeride trails and hit big features, get a downhill or freeride bike.
Eh? Any 130mm bike I've had has been more than capable of taking a bashing. Maybe not a DH course under a decent DH rider but pretty much anything up to that point. Nothing described on this thread should worry any MTB.
With regards the fork clearance, I have a 2.4 high roller 2 on 26 mm ID rims on a Sektor no problem.

The new 2017 Bossnut frame and the rear tyre does not touch the frame...
Right click on the image and select view image
Just picked up frame number three, still touching.
Getting a bit miffed now. It's a 25 mile round trip to my nearest store, and I've had to do it 6 times.
It's a blooming nice bike to ride, but I'm starting to lose the faith.
Chrispianlee - I'm not sure your's is a 2017, my new one is the same colour, but the reach doesn't seem any longer (hard to tell without back to backing them tbf) and my tyre still touches.
How much of a gap do you have on yours? The large one in the store when I took the first one back had a good cm gap at full compression, but I've not seen another medium in the wild, and my 3 have all butted straight up to the seat tube.
What's your plan now prawny? Didn't the shop bother checking the frame before you collected it?
It doesn't look that way. The mechanic doesn't work Saturdays, so I dropped the bike off and picked it up from a young lad that didn't really know anything about it.
I've emailed Mike back to let him know and see what he comes up with, in an ideal world I'd get a bike back that is right, or one of the new new ones when they're ready (I've just checked the linkages on the factory jackson story, mine is just a new paint job, same old frame). I've asked about getting my money back, which I don't really want to do, but cycle republic in town have got some Boardman FS Team and Pro in stock. So there's always that option if it comes to it.
Prawny - Is yours the same colour as mine? They informed me its the new 2017 frame and as I havent seen it elsewhere, or online. I assume thats the case as its different to the 2015/2016 colours. The length is only 1cm apparently, so minimal. I didnt measure the gap, I just let all the air out the shock and checked the tyre wouldnt touch the frame. Yeh its only the mediums that had the problem apparently. Thats ridiculous that they have replaced your frame twice and the tyre still touches!I would demand it gets rectified asap or you want a refund. Good luck and let me know how you get on.
Yep same colour, I had an email yesterday from Lisa (Mike is away) apologising again. She said the 2017 frames won't be ready until April, a frame that comes out in April '17 would be more likely an 2018MY bike though so they probably werent wrong saying this colour is a 2017 bike.
They've given me the option of a refund if I want, but then what would I get instead, I can't really afford to add more to it, so the only option would be a Boardman FS Team, which I'm less keen on. I'm really not sure what to do, I might just see if I can hang on until April, I'd hardly ride my MTB at all between now and March anyway.
My mate who works at Halfords bought a boardman fs team. He got rid of it within weeks because the back end was so flexy. He used to call it the bendy boardman. It may not be the best bike for you if you ride hard enough to bottom out the bossnut.
I Reckon you will prob be waiting longer than April for 2018 frames. If they cant get you a 2017 frame with the problem rectified, I would get a refund. Go Outdoors told me the problem has been rectified on the 2017 frames, which is what I have; with the problem sorted. If not, get a Whyte 901 hardtail 2016 or a Large Giant Trance which are going for £999 at Winstanley Bikes and Triton Cycles.
I'd ask for a refund, I just don't think i trust them to get it right. You should seriously consider the Marin Hawk Hill for £1200.
http://www.marinbikes.com/gb/bikes/description/2017-hawk-hill-multitrac
You get stealth dropper post routing, 27mm inner width rims, wide range 1 X drivetrain
If I were in the market for a budget full suss, thats where my money would go
chrispianlee, I got a replacement "2017" frame with the same colours as yours and it had the same issue. Apparently the 2017 frame is the exact same frame as it has always been just with a different paint job and by the sounds of it, some of them having the issue fixed. How much clearance do you have now with the shock fully compressed?
The marin is nice but it's 30% more expensive so it's not doable.
Choices seem to be a. Wait b. Decent hardtail (901 or similar) c. Sack it go back to my old mtb and treat myself to a new commuter with hydro discs.
I'm flitting between a and c currently, think I'm too old and tired for another hardtail, even a nice one.
I'm old and very happy with my hardtail. Just need a frame with a bit of"give" in it and plus size tyres. Or a fatty?
It wouldn't cost me a huge amount more for a Sonder Transmitter...
Definitely go for the refund, how about using the components of your old bike on a new frame?
Get the refund. You never know what you'll spot between now and the middle of next year, and you need the money in your pocket ready to go.
get the refund.. i've been curious about this bike but after reading this thread theres a not a chance i'd go near one, or a 'new' model. ever. i certainly wouldnt have ended up with stockholm syndrome like the OP or put up with this amount of messing around.
its simply not true there aren't more options. there are loads of options around 1K. (vitus for example..)
tbh. i've had two marin hawk hills in the past (HT ones) and they were both great bikes at the time.
what about the secondhand market? you can get some amazing deals if you shop around.. when going SH just keep some money spare to cover tyres/grips/chain/cassette etc
