Can I use a CroMoto Grande 29’er fork on my mmmbop with a large Marge and Endomorph fitted?
No.
You need either a Surly Pugsley fork or a Salsa Enabler Fork.

I've seen an endo on a 50mm rim in a bonty switchblade fork
There tyres are huge! 😮

This is how much room a fatbike tyre takes up.

It's not even fully extended - this was with a narrow rim. With a proper rim the tyre is 10mm wider. 🙂
Bang goes that idea then, was hoping that it would work seeing that I have a Grande 29’er fork looking at me on the shelf.
Build your own fork free.

Or sell the Grande fork and buy a Surly or Salsa fatwheel fork for about £90
Like that epicyclo, but I'm thinking that a 1/2 fat won't work that good due to the thinner tyre at the back?
found the pic, 47mm holm rim endo tyre and bonty switchblade forks

firestarter do you have any links for rim and tyre pls.
kris holm rims are avail from unicycle uk and its a normal surly endomorph tyre mate , try billys bmx for that

no worries 😉
Oh no...someone has fat tyres in stock...I may have to purchase.
I take it Endomorphs are not the best on the front though?
Just found these.. [url= http://www.trials-uk.co.uk/product.aspx?productid=756 ]RIM[/url] ...sorry for being thick but do I still need a 135 hub or can I use a normal front one with me fork using your set up firestarter?
lipseal the one above isnt mine its from mtbr but you would be using a normal 100mm front hub for it mate
edit.. on another thread ssstu advised to use a rear trials rim on a fat bike rather than a front one
SO..I guess the wider the rim is, the wider the tyre will be and might struggle to get the set up in the fork? I really could do with a borrow before I commit.
from what ive read there isnt a huge difference in widths between 47mm and 65mm rims but i spread about 10mm extra on a 80/100mm rim
i think coastkid had the measurements iirc
Measurements went up on one of the many recent fat bike threads.
Goes off to look.... 
Ok so been looking at other posts and I have a halo combat full wheel and the rim width is ment to be 36mm. So I'm guessing that I can fit a Larry or an endo on that? Just need to check the fork now and get the ruler out.
lipseal i knocked this together yesterday its a chubby semiskimmed fat bike lol

Been tying to find some 3" tyres, but there like hens teeth!
yeah they are i struck lucky with these 😉 you can get duro 3" tyres from unicycle uk
http://www.unicycle.uk.com/unicycle-spares-1/tyres/duro-wildlife-leopard-26-x-3-tyre.html/
someone linked to one on a trials shop on th can't afford thread IIRC
epicyclo did the measurements of the 4" tyres on different rim widths,
Been swaying on adding a fat rim 26" wheelset to the collection for my KM too,making it ridable on the beach for friends or may just get the 50mm Speedway cycles rims and run the 2.55 WTBs for a bit more float,
Think i mentioned it already but the Vredestein Black Panther 3.0 tyres are big fat xc tyres and really light- but not sold here in the UK, maybe could get them sent from Germany or Holland? 😮
Sell what you can and indulge in some full fat 4" F&R
Forgot to mention, firestarter nice build!
Cheers mate, I'm in half a mind to buy an enabler fork and fat wheel with a thicker rim out back but then I'd be afraid I'd like it too much and want fulfat and would have wasted money on this project . Decisions decisions lol
Mick.
Stop fannying around and just buy a fat bike. 😉
If I had the cash I would mate but I think I'd have to sell too much to make the numbers work
+1 firestarter
just looked on bike24, none of those 3" Black Panthers. will look a bit harder once I get on a pc.
I've just ordered a set of Chris Holm 29er rims 47mm wide. It'll be interesting to see how wide a fat 29er tyre will go on those.
May even approach the same flotation as a fatwheel.
What's the fattest 29er tyre available? Racing Ralph 2.4?
I think so epi the weirwolf 2.55 are quite narrow. I've been thinking similar but can't get the little thought in the back of my mind out of it that says get 26 wide ones built for your fat bike (that I can't afford at all lol)
WTB 2.55 spread the widest on 47/50mm 29er rims,
faster on regular trails than pugs etc but not as good on real soft stuff...so ive read anyway 😮
my 29er has these tyres on 37mm Halos and its alot more comfy than the 2.25 Ardents i had fitted previously..
will be putting 50mm speedway rims on the 29er soon and it will be a good halfway house between full fat and regular MTB 😮
am I right in thinking that the rim width is more important than the stated tyre width on these bikes ?, just starting to experiment with a 3 inch front and 2.5 back but on standard Mavic 317 rims for a pleasantly plump bike before the inevitable spend on a Pugsley 🙂
that seems to be the case Steve, maybe you've seen my other post re. 2.3 tyres on 70mm rims becoming2.9 wide (not much more to it than that, it was from a thread on mtbr re. raleigh xxix)
the whole thing confuses me 😕
hmm, yes I saw that and have spent all afternoon on MTBR as well, looks like the front tyre is more important as well, I'm seriously intrigued by these bikes (in am fact trying to talk Chipps into getting me one to test 😉
but for now I'm happy to play around with tyre and rim sizes 🙂
At the moment I've got an Endo with a Koxx rim (46mm) and a Pug non-offest fork up front, paired with a 2.8 Michelin tyre on a 37mm rim at the back of a 456.
It's actually really nice but can't comment on float as there hasn't been deep snow since I built it 😥
I really can't make up my mind whether to go for the full fat as per those ^^ as I think the difference may be too small to justify the extra cost but if it can be combined as an easy swap to 29'er and I can get rid of 2 other frames...................
I may have a lead on a new steel frame but don't expect to hear anything until after Christmas........ 8)
Aye it's interesting. I wonder if most of the appeal of the fat bike thing is that there's so much stuff to learn.
I'm going off to mtbr myself...want me to email/link to any good threads?
Am wondering if my unbuilt 50mm rim should get swapped out for a 70, someone linked to some cheap wide rims from Germany.
I reckon your onto something Al, lots of ability to bodge for (relative) cheapness 🙂
be prepared to waste a day or more on MTBR, there's so much to read, I just stuck to the posts with photo's in this afternoon
www.forums.mtbr.com/showthread.php?t=655762
I wonder if I have an old rim I can rivet to my 50mm one...
Al - 50mm should be fine. My 47mm with Endo seems to sit nice and wide. I'll take a pic and post shortly.
Edit - Bugger - at least I will when my battery is charged 😳
Found these rims, think they might be the ones you have woody?
[url= http://www.snowbikers.com/mtb_rim_echo.html ]RIMS[/url]
ta woody (that handle always makes me chuckle) I'm more thinking of what I can do with a narrower and cheaper tyre on my iterative/experimental foray into fat.
Lipseal - very similar, if not identical. I was told mine was a Koxx so I suppose quite possible they are made by the same people as I'm not up on trials stuff at all.
There's a lot of useful info on the [b][u][url= http://www.mtbtires.com/site2/ ]MTB Tires*[/url][/u][/b] site.
I think once you've tried the big fat 3.7" Larrys on a 80mm rim, all your other tyres seem much too narrow.
Hence the reason I'm getting wider rims for my 29er - to make my RRs even fatter 🙂
*btw, there's a really good article on the use of dropbars offroad.cynic-al - Member
Edit:

That would be me - I've had 3 sets of wide rims of them so far, 2x100 and 5x80. Got a few wheels to build yet 🙂
The thing about the extra flotation on the fatwheels is you don't really notice it that much unless you have a reference to something else, eg you have ridden it on an ordinary tyre or have someone with you on an ordinary bike. From your perspective on the fatbike you're just riding over stuff.
They're not just for snow - they're great on climbs on loose surfaces and also on those knobbly rocky stretches.
Epicyclo - have you still got your drops on as IIRC that was the first build with the bodged forks?
Yup - even 2.2 WTB's on my 'normal' bike look like they are 23c when you first get on !all your other tyres seem much too narrow.
Woody - Member
Epicyclo - have you still got your drops on as IIRC that was the first build with the bodged forks?
I haven't got drops on the fatbike yet because I have an Alfine hub and the changer doesn't work with drops. I believe Santa is delivering a Versa drop lever with Alfine shifters though, so I'll have drops on it shortly.
There are other mods coming too.
BTW if anyone is headed over to [b][u][url= http://forums.mtbr.com/forumdisplay.php?f=164 ]the MTBR fatbike forum[/url][/u][/b], I'm Velobike there (it was my name here before I had to change it after the Great Forum Hack of 2009)
sorry I posted that before I'd finished.
it was a different link lipseal.
epicyclo my point is that a 70mm rim seems to be a lot more capable than 50mm...I put my 2.5 Diesel on my 50mm rim and the profile didn't change much.
cynic-al - MemberAye it's interesting. I wonder if most of the appeal of the fat bike thing is that there's so much stuff to learn.
In all honesty Al i've always been interested in buying a fatbike since I had a ride on one a few years ago.
Buying a fat front for one of my bikes lead to buying a fat front for another then buying a full fat bike.
But a bit of it has got to do with the fact that the only way to find out how these bikes will feel on an "every day" ride is to own one and try it for yourself.
Sadly there aren't more people out there that are prepared to do the same thing instead of going on "someone I know said this about this kind of bike shite"
As with most things the only way to find out if it suits you is to try it for yourself.
You're definitely doomed once you try a fatbike - even just on the front.
I feel doomed after my 3" 26er experiment on the monkey lol
well I hope you are right guys but I will dip my toe in slowly just in case...

Looks good
It's on 32:18 which is ok as the snow isn't deep at the moment but I'm going to go 1 x 8 when I get back from Scotland.
Would have loved to have taken it with me but the ski gear and all the other Xmas bits means no space in the car 🙁
epicyclo did you get your rims from this place you linked to?

how is the weight?
Like that Woody!
took the half fatted TD:1 out for a spin today, felt good. i think running the rear at 20psi certainly helped, all good fun

Nice mocha, what fork is it?
that's a 100mm non offset Pugsley fork - spot on length with an Endomorph.

(nb scale was zeroed with the pencils in place)
Anyone looking for a taste of "full fat" I'll be in Dalby again tomorrow, yes I know the trails are closed, but even the Forest road is pretty challenging at the moment
Should be in from 10.30-11am until 2'ish, bike is a 18" Pugsley with SC32's on the front, Larry front, Endo rear, crank bros pedals, geared but conditions limit number available 😉
Post up here if your keen 🙂
Be warned you will end up buying one once your riden it 😉
A few more half fat pictures for folks that are tempted.

Stop it.... Stop it ...... Hopefully the snow will go soon and these fatbike thoughts will be a distant memory as I race around on my 29er with big -ish tyres.....
I like the look of that Salsa, from the States or bought here? Off to look at it's hub set up etc....
You realy think the longing will stop when the snow's gone?
Half fats are fantastic on rocks too. 😀
The half fat's UK brewed and the full fat's an import.
Full Fat is still ideal come summer, here a big day out on the Cheviots...

cheers epicyclo, I hadn't seen this when I pm'd you on mtbr.
EDIT Bruce - Cheviots rideable on a normal bike Shirley?
Cheviots is fine on a normal bike for sure 😮
still doable on the pug for giggles
It was the driest i had ever seen it that day up on the Cheviot, hence the Wellington bomber wreck raised out the peat,
That day it was still wet up on the top of Dere Street before Windy Gyle,
If when very wet as in winter the Fatbike is good on the spongy wet grass trails and also dosnt cut the ground up as bad 😉
coastkid - Member...
...If when very wet as in winter the Fatbike is good on the spongy wet grass trails and also dosnt cut the ground up as bad
For those south of the border who have to fight for every trail, this is important.
A fatbike does less trail damage than a walking boot, in fact it tends to compact the trail.
Maybe the ramblers could be chucked off the trails in winter because of the damage they're doing, and only the environmentally beneficial fatbike riders allowed. Well maybe in the flying pig season 🙂
Agree!...Its not about these bikes being better than normal MTBs away from Sand and snow but there low impact footprint on fragile terrain which folk should think about...
I chuckle to myself when sometimes walkers scourn me when i pass them cycling on the local Nature Reserve which i am legally allowed to do on the sandy paths yet there footprint is more compressed than the Pugs 😮
Ta Bruce, good insight into where fat bikes work well.
I guess my interest is in extending my riding. of the trails I know I can think of only a couple that might be rideable only on fat (path on side of Loch Etive). beyond that it's maybe more explorational or snow/sand.
i found this from MM 2006, i should have ordered one then!.my body shape matched the tyres at the time
