@kayak23 Not sure if they're identical, but these off eBay look similar...
You can actually dismantle it and replace the bearings. But it's some weird size, I got as far as finding that out before I demolished a crank arm taper by not tightening it properly.
Cheers.
Did you happen to note down the bearing size Northwind? Would be good if I could just replace them but in still riding it despite the creaking so if you had that'd be great.
Hi bearing size is 17x31x10, easy enough to do ,took me 45 mins & cost £10 for 2 bearings delivered from airebearings in Leeds.did a picture how to on facebook/ calibreduneowners
anyone want to sell me a medium dune?
been posting wanted ads for ages but nobody looks at those things!
am keeping a close eye on ebay, and there's fairly high turnover, but a lot are chain-sucked or the sellers just aren't willing to post.
give me a shout if you can sort me out
ok, finally got one : )
wandering, has anyone made up a set of 29er wheels to swap in?
don't get me wrong, i love it as it is, and bluto arriving next week i'll love it more, but i can imagine a use case to convert into a more regular hardtails for certain types of rides.
also will 29er rims/tyres fit in a bluto?
Put 4.8" Jumbo Jims on at the weekend and got out for a quick spin this morning. Best upgrade so far, so much faster than the old Juggernaut Pros it's not even funny...
Also, the bike looks like a proper monster truck now! 🤣
They're awesome aren't they?
Every time I looked at them when I first put them on they just made me smile in their ridiculousness.
They still make me smile but look more normal now 🙂

You get used to seeing the big tyre out front, so it sort of becomes normal. Friend in the village was round this morning, so gave him a shot on it, round the garden. Only then, seeing someone else ride it, did it sink in that they're really ****ing massive! 👌
I think it looked better on 4s tbh. But I'm pretty used to the 4.8s now. Mine came with the 4.0 JJs and for my use, the 4.8s are just miles better.
So this happened this morning, which was unexpected...
I don't have the money to upgrade the drive train to SLX this month, so am looking for a replacement 8-speed rear mech. CRC have the same piece of cheese, but I was hoping that the ALIVIO M4000 9-Speed rear mech might be a better replacement. Does anyone know if that mech would work with an 8-speed chain and shifter...?
Anyone know what length steerer I would need for a bluto fork on a Dune? I'm not near my bike so can't measure it.
Anyone replaced any spokes on the dune and know what length to order?
Got a tree stuck in mine the other day and lost a rear spoke.
Still riding it so if there's any way of ordering it before breaking the tubeless set up down, that would be great.
Looking for recommendations and sources for some tyres and a crankset and bottom bracket for my calibre dune please. Was thinking 4.8 jumbo Jim for the front and 4.0 for the rear. The ones I can find at the usual places are very expensive .
Cranksets - can anyone simplify all the different standards for me ,there are plenty of SRAM cranks for fatbikes on eBay etc but I'm not sure if suitable for the 197mm back end on the calibre.
I would be happy with a double up front or a single with a bigger cassette. I currently have the standard 2x cranks (which would be fine if I could get a new bottom bracket to fit) with 10 speed deore shifter,mech and 36 tooth cassette.
Has anybody had any joy getting any of the standard parts from gooutdoors yet? As I am going to need a back wheel before too long as well.
Maybe I should just buy a new bike!!!
Thanks
I run Jumbo Jim 4.8 front and rear. The rear buzzes the chainstay a little at certain pressures but I think it's because the tyre became deformed. It didn't do it when new.
I have a noticeable wobble to my rear wheel now, plus I lost a spoke the other day.
It s for chain clearance reasons with 2x that I was going to opt for another 4.0 on the rear.
I've got a couple of dings and a wobble on the back wheel too,I really wish gooutdoors would hold spares in stock for these as I've really enjoyed it over the past 2 years plus.but getting parts is a bit of a pain in the arse.
Oh I see, then yes the 4 is probably the best bet.
I think Go Outdoors are unlikely to stock spares really..only interested in getting completes out the door. Still, awesome bike. Can't fault it.
Hi,
got a Dune the other day, great fun. Bought minion's FBF and FBR 26 x 4.0 and put them on the stock rims. The come out at 3.8 inches/96mm and approximately 28.5 inches diameter.
Has anyone put a 29 x 3.0 on the rear?
Want a few different wheel sets.
The brace on the seat stays looks like it would a few mm's in the way. Loads of clearance at the Bottom bracket though.
Also thinking about a 27.5 x 50mm(i.w.) wheel set to run 3.25 and/or 3.8 tyres.
No issue with clearance with them.
This article shows 27.5 x 50mm with 3.8's pretty much the same diameter as a 26 x 4.8.

Cheers Tom.
Cracked my replacement frame in just over a year again,went in exactly the same place as before. That's it for me, will get another fat bike at some point but it will be a named one that will hopefully last a bit longer !
Unlucky. Mines coming up to 2.5 years , it's had a pretty hard life and many of the parts are well worn or have already been replaced but the frame is still holding up, even the paintwork still looks pretty good.
To be honest if it died now I would have had my money's worth many times over and I'd consider buying another one
Did the frames break near the bottom bracket / chainstay area?
My bikes on its 3rd winter, ride it pretty much like any other bike apart big drops and it still in one piece. If it dies now considering the cost v fun I'll be happy and buy a replacement frame for my parts from someone else.
Maybe a Smokestone or ICT
On the plus side it has all the “right” standards, so you could transfer pretty much everything onto my ICT frame (for example). Good luck breaking that.
Here's the Dune with 26 x 4.3 Surly Edna up front and a Duro Crux 27.5 x 3.25 out the back.
Good news is the 4.3 Edna fits on the Dunes standard rims in the back, and came up 4.2 inches.
Great tyres the Edna's. Monster grip and rolls well for a proper fat tyre.
When I saw pictures of the Duro Crux 27.5 x 3.25 I thought I'd like a Wheelset with these.
So just the rear wheel at the moment.
The Crux mounted on a Halo Vapour 50mm comes up as 3.2 inches. And just over 29 inches diameter.
I have never done tubeless before, and the Halo Vapour made it a piece of cake. Awesome wheels. The rear cost £179
Took it for a 1.5 hour ride today.
The Crux has huge grip everywhere. Not quite as much as the Edna on loose over hard, but today I went up a wet muddy track which is really rutted and powered up it, out of the saddle. The Crux just dug in. Very impressive.
Rolls very quick and quietly on tarmac too.
Obviously it doesn't have the float of a fat tyre, but its not that far off.
So this is an interesting combo. Fat up front, faster semi fat out the back.
The 2 tyres have almost the same diameter.
The Duro Crux comes in 29 x 3.25 too, so thats next for the front.
Sorry don't know why the images aren't loading.
Can someone give be some help please, my bottom bracket 150x151 is knackered, has anyone found a replacement?
Go Outdoors said they will press a some'sort in for £120 ish.
Also my front head bearings are grunting if I tighten up the Alan key too much, is their a link to a replacement?
Sorry to be cheeky as a newbee. Lol
You can replace the bearings on the existing bb for around £15. You want 2 bearings,17x31x10,google that fsize. I got mine from airevelo bearings in Leeds.if not already done so join calibre dune owners club on facebook, I put a how to on there last year so you’ll need to search for the thread
The headset is a cheapo one,
FSA No57,available from China via ebay costing around £23, I managed to find a U.K.
supplier after much searching but to be honest your as well just changing the complete headset.you want a 44/56 inner diameter (ID) Headtube 1-1/8" to 1.5" Tapered Headset,zero stack. Uberbike have a limited no/colour in stock & usually have a sale on
Dunerider, your a star thanks so much for your help. I love my dune but bloody hell they don't half make parts difficult to source.
Cheers
It's tricky if you want to replace like-with-like, for sure. But equally it's easy to find equivalent or upgrade parts. So frinstance probably half the Dunes out there end up with Aeffect fat cranks.
Had my Dune for 2 months, second hand from eBay.
Its cracked around the BB/Chainstays.
Bummer as I have just bought loads of upgrades.
I'll FB Calibre, they sorted me out a rear mech hanger twice for free.
That's a real shame mate.
Worth a try with Calibre. Perhaps a discounted frame as a gesture of similar?
Just bought a secondhand, but in very good condition Surly Wednesday, only items that I couldn't swop over off the Dune were the rear wheel & the seatpost - So £350 later I've got a new fatty again.
Added up all the upgrades you need to do to the Dune to make it decent (tyres, brakes,h/bars, dropper post & drivetrain)soon realised that I'd have been better buying a decent secondhand frame & speccing that up as wouldn't it have worked out any more expensive(probably less TBH) & I'd have had a better frame all round.
Don't get me wrong I enjoyed riding my Dune(both frames !) & did a lot on it, but believe me when I say the Wednesday is Soooooo much better than the Dune ever was !
Does the Wednesday feel heavier? I mean, it's bound to a bit, but very noticeable?
I reckon that's what I'd get if I ever kill my Dune.
I’ve still got a large ICT frame in the shed if anyone is interested. Wouldn’t even need to change the rear wheel 🙂

No, if anything it feels a bit lighter & nippier, which may be down to the fact there's only enough room to run a 4.0 JJ at the back. Which I thought I'd really notice out on the trails, but it feels fine & the steel frame/fork feel much nicer on the trails..
Anyone know where to get a replacement front axle nut for the Dune?
Realised mine must have fell off today loading it into the car after a ride 😥
Just picked up a Dune this morning, it looks ridiculous, but in the best possible way!
Unfortunately my old parts bin brakes and reverb don't have long enough hoses to route along the downtube. It'll look messy but I'll just cable tie them to the toptube for now. The brake isn't worth dicking about with hoses for.
Go Outdoors bike technician was nice enough and the forks are the correct way round. I'm impressed the tyre logo's are properly aligned too.
I had to use some straps to lash the bike on my Thule 598. I'll look at getting the proper feet but for now it's a bimble from the door bike/child duties.
Pictures!
Go on then..

Completely stock at the moment. I've some old Juicys that will route along the downtube. Reverb will have to be cable tied along the top tube though.
1*10 to go on and tubelessness to be sorted.
What's the easiest way to tubeless it with stock rims and tyres?
Little ride up the road and it rolls well. Brake levers are shocking! The wider Q factor will be good for the Mac-Ride too.
Congratulations,they are a great cheap bike.
The split tube method with a strip of foam camping mat worked for me but it was a bit of a pain in the arse to say the least. A compressor helps.
Lots of information about the dune on this thread https://singletrackworld.com/forum/topic/would-you-buy-a-new-fatbike-for-1k/
My Dune is taking shape now. Nukeproof bars, Race Face stem, Guide R brakes, 1*10 and Reverb fitted. Just needs heli-taped.
All the bits gathered for some ghetto tubeless action too.

It really does glow in the dark doesn't it!
Is anyone running 203fr/180rr rotors on their Dune?
Guide R's are ok but I feel would benefit from bigger rotors if the frame and forks allow for it.
Was looking for something else and came across this thread. Thought I'd share. My Dune is still going strong! It's the newer "large" frame but it's still quite small.
Bought to see if I liked fat bikes. Replaced pretty much everything very quickly. Only frame and wheels original. Everything else upgraded.
-RaceFace Ride Crankset with 30T chainring.
-1x11 Shimano SLX everything else. 203mm rotors front and back.
-Schwalbe Jumbo Jim 4.8s.
-RaceFace Atlast Stem and Bars.
-RaceFace Seatpost
-Fabric Scoop Elite saddle
-Axiom Fatliner Rear pannier rack with ROS bags.
I only really use it for general riding. I like it and it's a real head turner but you always want something new.

Looks cool, and quite like mine 😎
Do you find your 4.8 Jjs rub the inside of the chainstay?
Mine do a fair bit. I think I've wanged it heavily round a few too many corners and misshapen the tyre and probably wheel.
Yeah. I get a bit from time to time. Mainly on the drivetrain side.

My main issue though was whatever mounting point was here. Ended up filing it off:
[url= https://i.ibb.co/P4SRwHc/IMG-3162.jp g" target="_blank">https://i.ibb.co/P4SRwHc/IMG-3162.jp g"/> [/img][/url]
My JJs don't seem to be perfectly finished, there is some excess material at the middle seam. I had to send a pair back before these that were all cracked.
That's quite interesting, I didn't have any issues with 4.8 clearance on the original (medium) size with my 4.8 JJs and Minions, but that definitely looks tighter. (that stupid boss is the limiting factor on mine by quite a lot).
I did find that if I pumped the tyre up high it grows enough to foul, which is an odd thing to see but at any sort of normal fatbike pressures it's got enough clearance. Not huge but enough.
I run mine pretty high (20-25) unless it's been snowing or something as most things I ride are pretty flat and I like to speed along. It doesn't give people time to ask questions 🙂
Hi folks, sorry to jump straight in with a question before introducing myself!
I've had my dune long enough to crack the frame and replace it, I've now worn out the freehub pawls. Has anyone identified a replacment freehub / pawl set from anywhere? I cant find any markings on it nor any helpful info on the KT Hubs site.
It looks very much like a Halo Spin Doctor....
What fork travel would suit the Dune best?
I'm guessing 100mm, but I can get hold of a 120mm a bit cheaper....which is better obvs.
