Aye that's what I meant above - reports seem to be that a wider rim is needed for lower pressures.

That thread is about sub 50mm rims - more like 30mm is what they're on about. I'm not convinced that the extra 3lb or so, more weight is justified by the extra float.... JMHO 🙂
Hairy - It took me 2.5 years to put my bike together! Saving the pennies and accumulating parts at the same time.... worth the wait though 😀 Now I just with this flu would clear up and I could ride it!!

3Lb difference?
I'd check your scales. 😉
Seriously try a wider rim for yourself.
What width rim is that on the front futon
Hairychested - Member
...BTW How did you know where to drill?
Ran a dressmakers cloth tape around the rim, took the measurement and divided by 32.
So are these fat bikes good all year round? A few have commented but lots of posts about the spec etc rather than how they ride.
Not moaning about the spec type chat as all information is useful but just looking for opinion about the ride all year round rather than when just snowy or sandy

Have a look at coastkids video
Firestarter - the rim is a 50mm Uma by Speedway.
I was thinking that the 100mm rims weighed 1560g? As in this thread: http://forums.mtbr.com/showthread.php?t=586418
The 50mm Uma weighs 750g IIRC so a pair would be 1500g as compared to 3120g - the difference is 3.5lb - there may be lighter 100mm out there!
Stu - funds are a little hard to come by at the moment - but if any rim is going to get fatter, it will be the rear wheel that gets fatterer. I'm very happy with the way the 50mm front rim performs. What advantages can I expect from a 100mm front rim, bearing in mind sand does not feature in my rides at all.
Mantastic - I ride mine all year round, no reason not too 😀
I think 100mm for a front rim on a fatfront bike is going a bit too far but the 80 does make the tyre a lot more stable than a 65 at lower psi.
I'll be going fatter on the back too when my fullfat bike arrives. 😆
when are the two salsa fat bike owners having their group ride then ? 8)
Cheers futon
And stu remember to send your cast offs my way lol
My semi-skimmed should be ready soon 😉

Just over 850 grams. So an extra 30mm for just over 100 grams 😉

There'll be three that i know of and I'll not be riding with any of them because as you know i'm a right antisocial barsteward. 8)
Stu - what low pressures are you thinking? Lower than 8psi?
6 maximum.
OK - that IS low - I ran mine at 6psi on the icy/snowy roads last week - no problem, but obviously nothing like singletrack riding. So you only run yours at <6psi? Mine spends its time at 9ish psi. I'd love to try out someone elses first to see if the upgrade is worth it.
Futon River Crossing how much was your frame?
Just love the look of these bikes equally keeps adding to the want
for one.
$5500 - A lot cheaper now: http://www.jonesbikes.com/production_framesets.html - they are now made in Taiwan, not the USA. You'll need to add VAT and duty and shipping 🙁
Still have not seen another fatbike on the trails.
fantastic vid, coastkid
Cant't believe the ****ing thing floats, thats awesome!
oh, and i want one too!
how do you measure pressures that low??
flashes - Memberhow do you measure pressures that low??
With a low pressure pressure gauge. 😆
I know this is a real long shot, anyone in Worcestershire own a pugsley I can have a nose at?
I'm not far from Worcester.
You're welcom to try my Mukluk when it arrives.
Cheers for the offer stu, am in Bewdley so not far. I will keep a lookout for your posts when it arrived
So, what frame will allow me to run two 135mm SS wheels? Pugsley or what? Need to know if I'm to be saving a few quid a week for a year.
singlespeedstu may I ask what a Mukluk is
Do you have a pic mister
Digital gauge for low pressures is essential as 1psi can make a big difference. There's a mukluk on page 1 of this thread - it's the blue bike.
May i point you all in this direction for answers to many questions.

Brillaint on snow, even up to 8" deep when soft and no problem on hard-pack. Excellent on dunes, wet beach sand, peat bogs, game trails, heather moor and just about everything else. Don't think about buying a Pugsley or other Fat Bike, just do it!

Oh a steel Jones is in the realms of affordability but I think it should be ti really for a Jones . MukLuk looks nice I could prob get frameset Jan but couldn't afford wheels for a while
And my karate monkey would have to go too 🙁
Found some light 80mm rims Flattop - 790g!! I can resist anything except temptation.
frc.
It [b]does[/b] make a big difference being able to run the tyre that bit softer without it washing out when landing on off cambers and cornering hard.
Pugs has been the most fun bike ever owned...
Im now running my Larrys on 65mm marge rims at 5 psi front and 6 psi rear...i use scrader valves and a motorsport gauge for pressures,

this wasnt very good with the old 60 TPI side wall endomorphs but great with the new 120 TPI tyres, oh the Endomorphs are now available in the thicker sidewall and which ever tyre you go for (if buying new) get the 120 side walls as way better, id recommend Larrys for front and rear for our terrain and condition here in the UK...
Good to see you Saturday Gary! (even if on foot!)

As Gary knows im selling all my other bikes and frames and parts not needed apart from the pug and KM 29er to fund a new lightwieght fatbike for XC riding next year!,keep the pug as the Tiger Tank/ride through anything expedition bike 😮
new bike should be a sub 28lbs build 😉
be interesting to see what my sandman comes up at when its built ...
the 100mm rims are drilled to hell - there isnt much metal about them
will be sure to weigh it 😉
Ti Fatback? Coastkid.
Found a frame now can some one point me in the right direction
where to get a set of wheels/rims from please.
Ti fatback is what i did want but recession has said it will now be the 9zero7 frame and there 80mm (drilled) rims,offset rear and inline front.
Being a offset frame like the surly allows a normal rear hub and i already have lots of Hope stuff,hubs,brakes,headset,seat clamp,
Phil Wood BB and middleburn cranks,carbon bars,post,1x9 XT, so should be a light build, be great for big days out on the hills...
Also i like the guys at 9zero7 and there real keen to export to here in the UK. Also my epic frame bag will fit it being roughly the same triangle as the grey pugs 😮
Thought to share....
Re: comments on a 29er rr wheel not working on an offset rear end..has anyone tried offset drilling on a wide 29er rim?
In any event, if the rim/tyre is slightly offset relative to the rim, is that a big deal?
Hmmm those 9:zero:7s look nice - alu is only $499 too!
Dam it looks like i wont have the 1st one here now! 😮
I like them because its straight top tube and anodised red finnish
Aluminum is spelt wrong on the frame for here though!

So, what frame and fork set will allow me to use two SS rear wheels with a regular 135mm spacing?
Pugsley
aren't they off set?
All I want is two same wheels so I could have different gear ratios on hand.
The frame and fork are offset on the Pug so you can swap front/rear.
Only the Pugsley frameset uses the 135mm rear hub (offset) fork up front for interchangable wheels so that is what you want if singlespeeding one and want options on gearing 😮
EDIT;as just said! 😮
But if the bike is to be gearless AKA singlespeed, will the Pugsley allow it? I have two SS cassette rear hubs on the shelf.
Mine is SS fitted with 2 SS freewheels.
Do you have to remove the caliper to swap wheels or is it me being a numpty?
Hairychested are you basing a bike build on 2 sprockets?
You dont have to remove a Hope Mono caliper but you do an Avid BB7!,
i have the Hope on my Karate Monkey which has the same dropouts,
if you have to remove it for clearance to get the wheel out then all you do is loosen the top bolt and remove the lower bolt- then pivot the caliper and hand screw in the lower bolt a few turns and its out the way 😮
Or use Hope bolt up hubs.
Just unscrew the bolts and the wheel drops out the bottom. 😀
Pretty much so, I have two hubs and sprockets. Good enough a reason for a new build?
Pfft. Real cyclists start with a valve cap or M5 bolt 😉
What front racks and mudguards are you guys running (particularly Gary)? I'm looking for something for the front of my Fargo that will allow me to run my Big Apple 2.35's (which come up a bit bigger than Weirwolf 2.55's). I've looked at the Surly Racks but they seem expensive for what i'd use them.
Those Big Apples must be huge! I thought my DMR Moto's at 2.4 were big but they are still smaller than a 2.5 Weirwolf.
They are pretty big - dead comfy though. And a proper pain to fit onto my Stans Flow rims. The new folding version are £50 rrp though - for a fairly heavy slick!!!
At last snow..............well that was a good day....

A Mukluk! How's the rear traction in that soft snow?
heee! another!, its great eh? 😉 😮
coastkid that 9 zero 7 looks great - where did you get it?
Don't think I'll ever be a fatty, but loved your vid Coastkid. Makes me want to start planning adventures for next year.
I Havent ordered it yet,made myself a deal to shift all the old stuff first 😮 but heres the link; its Chain Reaction Cycles Alaska,no relation to here in Ireland, [url= http://www.chainreactioncycles.us/907.html ]9zero7 fatbike frame & rims[/url]
Cheers - that was the site I found, and yes I thought it was the same lot at first 😆
I don't like 9zero7 frames' looks. Salsa is so much prettier.
FRC - It's fanstastic in todays snow. Tomorrows ride on the frozen snow and ice might be a different story.
It feels very stable in the snow and sand over "our" other bike but with 50% more weight
If I could work out how to install the bl**dy software that would allow me to download pics from my Nokia phone, I'd post pics...........
Couldn't believe how good it was in snow. Sooo stable, no drama, overtook cars, going over to ,Leigh Woods, good on slush as well. Brill...........
I made a wee film mid week after work on a summer evening 2 summers ago on a local trail mounting a compact camera above the pugsley front tyre...
The film caused a massive interest in a bike with a tyre that "ate the world" as an American described..looks like one day i may make another film (Larrycam?) with another fatbike in front 😮
im amazed at the UK interest 😮 but its all good...
bought a tap and dye set today ......
home made 165mm rear hub coming right up - just need to find a donor 135 36 hole with an alloy axel i can tap ....
found an old hope big un axel to canibalise for a spacer ...
drill it enough to allow the bolt to go through the axel
counter sink the other side to let it slide over the axel
tap hub axel
long bolt through the lot ....
then long spacers on the disk mount
it wont be pretty but ive seen it done back in the olden days on my 98 big uns and on my mr big st 10
MrTall - OMM racks will certainly fit a 2.5inch tyre (I have one fitted to a Pugsley 100mm spaced fork) and I'd expect even the superfat Surly snow tyres would fit - have a look at:
http://www.carradice.co.uk/index.php?page_id=category&category_id=35
Must admit I'm getting a bit fatbike curious 😳
I'm confused about the rear hub is it 135 or 165mm? If its 135 it would take an Alfine, correct?
Need to have a look/try of your fat bike terry. 😉
There's loads of different "standard" rear spacings on different fatbikes.
t_r, I have a big_un with the bolt-thru setup. How would you make it into a 165mm? Curious as it might allow me the Salsa frame not a Pugsley (prettier and lighter). Thanks!
You do know you can run a 135mm hub in the Salsa with there adaptor don't you?
I was wondering if that adaptor would fit other frames as it would save the faff and expense of a new hub and keep the front and rear wheels interchangeable, even though Salsa say it needs a wheel dished 17.5mm to driveside. I'm also a bit concerned at the additional strain this would put on the chain/seatstay area (if any) but it's late and my brain is starting to hurt thinking about it!
No, I didn't. I was just wondering if it were possible to use that hub with a bolt-through and a tubular washer to space it to 165 when I noticed the bodge/fix. I'm wondering if the offset rear wheel built on a Big'Un, due to the inherited strength of the hub, was strong enough for the rather large 17.5mm offset? You know, all the talk about spokes being very loose on a non-drive side.
MrTall,
Front racks are Old Man Mountain Cold Springs, fitted both front and rear. Made custom lower brackets to get them to fit as I wanted, i.e. lower. Choose these because they have a "rugged" look and add (I think!) to the overall look of the Pugsley. More [url= http://www.pugsley-on-patrol.org.uk/equipment/racks.htm ]here[/url]
The mudguards are actually those used on trial motorcycles here in the UK. The rear was made from two spliced together. Mounting brackets were fashioned from some aluminium flat bar. There work well but do not stop everything. They would work better if longer but then they catch on bushes, rocks, etc, so a bit of a compromise.

I Guess you`ve looked out the window this morning Gary? 😮
Yes, just about to have a wee coffee first, then break open the shed and ready the Pugsley. Might wait a while for it to get a but deeper, then the left-over hard-pack from last time should be easier to ride across. May take the Go Pro and make a vid.
Gary
Is there anywhere you can actually just buy a set of fat wheels? As I don't have the skills / time to build any.
