Mine should arrive next week. How essential is it that I buy some Hope QRs? I suppose it depends on how much I would enjoy the wheels falling off.
Seriously though, how much of a problem are the On One QRs?
Collecting my Fatty tomorrow from On-One Edinburgh.....excited!
Do I need to factor in new QR's as well as better brakes?
chrishc777 - MemberHow much pence al?
If that's not a joke, email me! (frame only for sale mind!)
Not had a problem with my qrs. if you do get some hopes, remember they're a funny size: iirc front is a standard 135 rear, rear is 170mm weirdness.
leeph - I picked mine up today from Planet X in Edinburgh. I got an email on Wednesday saying it was ready but they're a bit snowed under at the moment and it was still boxed up when I went to get it. The guys were great but worth giving them a call if you haven't already just to save you waiting around.
Cheers hot fiat.....will try before I spend more cash.
Let's hope for snow!
I wouldn't rush out and buy new qrs straight away. My first fatty was no hassle and my new one appears to have a different design of qr.
Had a look at mine last night whilst changeing the tubes* and tyres over. The ridges machined into the QR ends are pretty blunt. When I've got 5 minutes I'll file them into something a bit sharper and more pronounced just to be safe.
*Are they actualy motorcycle tubes? I'll send them to my dad to use in his Royal Enfield!
cynic-al - cheers for the photo's, I think I'm gonna have to get the drill out on my rims. 🙂
Also I found the front QR gave me a few issues with the wheels moving a little in the dropout causing the brake to rub. A shimano rear QR works great on the front.
Wow it comes in the biggest box ever 🙂
Wow it comes in the biggest box ever
I'm hoping so for my 3.5 year old sons sake. Hours of fun to be had playing in a massive box.... 😯
[i]I said earlier...[/i]wouldn't rush out and buy new qrs straight away. My first fatty was no hassle and my new one appears to have a different design of qr.
And I got back today to hose the Fatty down and the rear wheel was half out of the drive side dropout. /facepalm
Back to tubes, Schwalbe SV 13F.
Saw 2 kids aged about 6 or 7 on mongoose fatbikes in Ealing park today
Edit, was this one

Flying RM Blizzard
Exactly the same issue, rode my new bike yesterday up near cheviot and today on the beach. Thought the rear brake needed setting up properly - turned out to be the rear drive side skewer half of the dropout.
What's the fix? Hope skewers?
Going to try the file option first. Hopes are £30 a pair and Salsa Flip-offs £45 ish. Salsa come in Orange if that helps... 😉
My gears felt like they were skipping, rear QR slipping? Couldn't see any evidence of it but couldn't find anything else wrong.
I use a Hope QR on the back, and a Shimano QR on the front. No issues.
Ordered some bragain Hope QR's, in purple* for £16
*clashes horribly, but at least they're not bland.
Trekster - what do you think of the RM?
Also - where is that picture taken?
I've had mine a week now and given it a pretty good test over three rides. I'm really happy with it. It's the cheapest bike I own but I can see it becoming the most ridden.
I gave it a good run along the coast on Sunday. I felt like a big kid playing in the dunes and just cruising along the beach at low tide drawing shapes on the sand. There's a lot of exposed bed rock on the coast here so it's opened up some fantastic technical bits of riding close to home that I never new existed. Fun, fun and more fun.
I gave it a go in some rooty woodland stuff as well. With the wide bars and slack set up it's great on the singletrack and the grip is crazy on the wet roots. Bits that just wouldn't be fun normally were great.
The original tyres were rotten, swapped for Floaters which I'm happy with. The seat post is a shade short even for my stumpy legs on a medium frame. Other than that seems good. I'm looking to drill the rims out, lighter tubes and maybe put a carbon fork on at some point. It is heavy, and I can imagine it would be more fun if a bit lighter but it's definitely good enough as it comes.
Can't wait to give it a go in the snow and hopefully on some boggy hill routes in the highlands next year. So many new riding possibilities!
Just had the most infuriating ride ever on mine!
I presume it's the single wall nature of the rims, but the tyres don't seem to want to seat properly with tubes, too 3 or four attempts with a track pump to get the tyre vaguely round and not poping off the rim completely!
So cut to todays ride, afternoon booked off work, weather's looking reasonable, bikes ready to go.
1st hickup) Missus is ill, I got no sleep, then overslept so couldn't ride into work.
2) as a result of 1 I ended up working a bit later than planned, no worry though, by the time I've driven home I'll have made up the time lost, the ride will just be shorter.
3) realized I've removed the towbar bracket from the car and have no idea where it is, so the bike goes into the car.
4) At the absolute furthest point on the ride from the start I get a puncture. The tubes split completely, not the end of the world, I've a spare, and it was stretched quite a bit, maybe I was just unlucky.
5) get about 50m further down the trail and the tyre pops off the rim. Stop to let it down, re-inflate, try again, pops off, by this point it's getting dark and drizzling and I've had a sense of humour failure, my arm aches and I've run out of CO2 cartridges.
I've had tubeless woes in the past, but tubed woes? It was beyond irritating! Kept looking at the rim cursing whoever designed/spec'd it. Surely you could make a rim along the lines of the old Atomlab GI with the box section bits on the outside so the tyre doesn't have that huge step to get over?
Is there a knack to seating fat tyres?
This weekend I will be making life difficult for myself trying to tubeless them.
when i built my rolling chassis i had trouble with the tyres not seating evenly into the rims and giving the wheel an egg shape when spinning. i inflated them up to around 40-50 psi and they eventually sat correctly after i bashed them down on the floor on the high spots. not troubles since and still not trouble with my qr.'s either.
I've changed to rolling daryls
When mine arrived I pumped the tyres up hard as mentioned above and left them at 40psi until I went out on it a few days later. Try some soap on the beads to help them pop into place.
Still waiting for mine, being built in the 22nd so not getting my hopes up for a Xmas fat ride on the Quantocks.
tinas - not a problem with Surly rims. I'll leave you to ponder whether or not you maybe get what you pay for.
I don't think the rims are an issue (though they are very basic). It's the baggy fitting tyres that seem to be to blame.

Haha, I have a cunning plan.
I might be in the minority here but after a few months of oo fatty ownership I just found out both my hubs are convertible to 12 mm rear and 15 front with the supplied adaptors.
That's new then as the front axles on mine are 10mm id. The hub width and disc offset is also unsuitable for a bluto.
I think it's what the V2 bit is all about. 🙂
Slightly OT but .....
I ordered a On One fat front wheel (V2) to use in a On One segmented fat fork for the front of my Inbred - I already had the fork and the wheel was from when they were doing their 20% thing.
I run Schwalbe free ride tubes on my Puffin when using Marge Lites and Nates. Using the same tubes for the On One wheel and Floater tyre just didn't work, tyre kept popping off of the rim.
Tried a Surly toob and the tyre went on first time with no hassle.
Might just have been luck.
Haven't use it in anger yet as the wheel doesn't fit in the forks 😯 But on One are sorting that out for me 8)
I think it's what the V2 bit is all about
Ohhhhh, mine were labled as V2 on the spec sheet, didn't come with any addapters though? Presume I can just check by pulling the ends off and measuring the ID of the bearings?
The front is a simple pull off and check and the rear is too on the non drive side. I've found the drive side unscrews and then removes. I think the wheels are excellent for the money with adaptable hubs.
Fatty's are back to £699 on the Planet X site, too.
Get ready for the snow!
I got some of the purple skewers ordered @16quid shame not too......should go well wiv the pink tyres 🙂
I had the wheel undock once on my previous fatty but after I'd really cranked up the skewer it didn't do it again and also had the tyres sliding around the rim but that settled after pumping them hard then they were fine at 5psi..
Now about that snow 🙂
I've just converted the front wheel to tubeless, went up first time without sealant.
Materials:
1.5mm underlay foam (also sold as jiffy packing foam).
50mm Gorilla tape
Tubeless valve (cut from an old tube in my case).
Method:
Remove everything from the rim including the tape.
Cut the foam into 5x ~3.3m strips 60mm wide. Or try and buy some foam 60m wide if it exists, or some ~7.5mm thick foam would need less strips.
Starting just after the valve tape a bit of the foam to the rim and wrap it under a slight tension, the foam was slightly waxy so doesn't slip around. If you're using multiple strips like me, tape each one to the end of the last one. Untill you have 5 layers, stop just before the valve (same as all tubeless systems they work best if it's a bit thinner at the valve). This was enough to get the rim level across it's width inside with the step at the edges which is what was needed.
Then add a layer of gorilla tape, one on each side, making sure it goes slightly up the wall of the rim so that it's sealing the rim, I guess if it didn't you'd pump sealent/air through the foam. A bit of tension helps it stick to the rim and the sidewall without creasing.
Poke the valve through and do the nut up.
Stick the tyre on, it'll now be quite tight, but it'll still go on with just fingers and thumbs as the foam's squidgy enough.
Inflate with a track pump, got it upto 20psi and it stayed up for 20min so should be good with sealent, certainly a lot rounder than it was before 🙂
Total weight was 10g more than the original rim strip according to my kitchen scales.
Any photos
I'll stick some up as I do the rear.
Just stumbled across this site - http://sand-bikes.co.uk/#!home £399 for a fattie!
Local and tempting - anyone got one?
Sand bikes are pretty much the same as the other fatties around that price.
If you want a fattie to just play on occasionally and you have no intention of upgrading, then thats your bike.
It has a 7sp screw on block, so you would need a new wheel if you wanted to fit a cassette.
Here you go:
The 'problem', the rim has some box sections which catch the tyre bead as it's inflated and stop it poping up onto the rim, especially with the tube pushing it against the rim. The original idea was just to get it working properly with the tube, wasn't too fussed about tubeless.

The foam, in retrospect ~55mm might have been better, but I had a 30cm ruler and was being lazy, it might come back to haunt me if the gorrilla tape doesn't quite hold as it didn't leave much rim either side to stick it to:

Finished the tape just before the valve hole so there's about a 1" gap as I've found in the past that the area round the valve struggles to seat as it's too bulky if I don't trim the tape in a bit.

Pressing it in with the blunt side of the scissors:

Valve added, pressed it into the rim and nipped up the nut on the stem. You can see how tight the tyre is on the rim now, it's not difficult to get the tyre on and off, but it's definitely not going to fall off again! It's not so tight that the tyre's pressing into it but with a track pump it went up with no effort at all without sealant.

Good work TINAS that could be my next tinkering session (or shouty sweary session)
