update for on one fat bike rims and tyres problem

Ok so after a week of on one having my wheelset, floater tyres and carrying out multiple different combinations of my wheels with new tyres, my tyres on other rims etc etc they finally fitted them to an actual fatty and rode around for a day! Consensus? The tyres were faulty and not round! Also replaced the tubes and 2 new tyres and not only were they a piece of cake to pop the bead, but after letting them down they are spinning perfect.
God I am a happy man

Not so successful here. Did a couple of rides trying to run my Floaters at 10-15 psi and ripped a valve out of a tube on both, after the tyre rotated on the rim. Loads of faffing, doing my own investigation but mostly riding at 20 psi to be sure of getting back as beads always unseated at 16 psi while riding. 14 phone calls plus emails to On-One, tyres sent back for investigation for 2 weeks, wheels and tyres sent back for 4 weeks, still not resolved after 3 months and patience ran out in the end. Complete bike rejected under Sale of Goods Act for a full refund. Loved the bike but too much messing about and fobbing off going on.

Thats crap Stu 🙁 gutted for you pal!
Iv’e just got back from Wales and the bike was truly amazing!

Trek farley?

Took mine back last weekend, they agreed that the rear tyre was faulty, it had struggled to seat properly and kept poping off, then eventually the bead split and the tyre blew off the rim completely! Front seems fine so I’m guessing a QC issue at the factory. New tyre under warranty.

Has anyone had any issues with the carbon forks? My headset wouldn’t stay tight, keeps coming loose after a few miles (4-10 of normal trails, less than a a couple of miles if it’s really twisty singletrack). Guy in the shop thought it could be as simple as the expanding bung not being tightened up properly, but I though the bung/top cap was redundant once the stem bolts were torqued up?

Also had an issue with the BB, but that’s not a O-O part so can’t blame them.

Really hope it comes back working as it’s utterly brilliant when it’s in once piece and working!

I haven’t tried floaters but I did find that seating tyres was much easier with 4″ surly toob than it was with the 2.7″ OO ones. The tyres may have helped as I changed the Vee8s to Nates at the same time and they seated first go.

Luckily not had any trouble with mine since getting it back in November.

Happy with floaters and holey rolling Daryl’s here.

I still have egg shaped tyres and got to the point its almost put me off riding it. Lost track of how many attempts to seat tyres properly (tubed and tubeless).

Lube your rim.

Fairy or other soapy fluids… Slight over pressure pumpage and bobs your auntie.

Cheers but tried that, have also padded out the centre of rim as part of going tubeless to help bead get seated. Reckon I’ve spent more hours working on tyres than in the saddle, a right PITA.

In that case, sack it off, tubes and get the hours in riding as that’s what counts….

Edit, apologies, some floaters are not round, have a chat with OO ..

Discounted Pink Fatty owner here.

V8’s on mine stay round as long as i i don’t go too low on pressure. Must try the pink floaters i have to make sure they’re round! Still running tubes but have swapped out the weighty O-O tubes for lighter Spesh 3″ tubes from Evans.

No problems whatsoever with carbon forks, have stayed tight riding on all sorts. You are correct, bung should be redundant once the stem is tightened, not sure why yours misbehaves.

My bottom bracket did come loose. There was(is) a problem with the installation as the length of the crank spindle is longer than the bottom bracket width. This allowed the plastic tophat to drift out of the BB on the drive side causing the spindle to be loose in the bearing. I solved this by making a 3-4mm spacer that slides in the spindle between the drive side spider and the bottom bracket tophat so its a snug fit with no gaps between the two crank arms. Incidentally i made the spacer from a piece of the carbon fork steerer i cut off and filed out a bit.

Despite the faff the fatty is my go-to bike and get ridden everywhere, a lot.

My tyres have been fine.

As for the fork, mine did come a little loose in the headset after around 10 miles or so. After loosening the stem and tightening down the top cap a little more, it’s been fine ever since.

Floaters fine here on Rolling Darryls, can get them down to 5psi without issue

IMHO the use of undersized tubes can often lead to poor seating of fatbike tyres regardless of tyre/rim combination

For weight saving either go for the newer generation of lightweight fatbike specific tubes or go tubeless

my prefered option if either surly lightweight or schwalbe fatbike tubes with some Stans

Interesting, that’s exactly what happened to mine, they’ve replaced the top hat, I’ll see if that fixes it, if not I’ll do likewise and add a spacer, I did consider adding a couple of shimano BB spacers, or maybe more expensive GXP BB’s have a different top hat (metal rather than plastic)?

It’s an absolute unholy ball ache to get my floaters mounted properly on the OO fatty rims.

I’m just resigned to having a massive flatspot on the rear. It’s only a big problem when riding on tarmac.

[It’s an absolute unholy ball ache to get my floaters mounted properly on the OO fatty rims.

I did the soapy water and also silicone lube but to no avail. Also, it’s not really all that practical to do out on the trail when you get a flat.

On my BB I just put a ziptie around the spindle to fill the gap. Has worked so far! My tyres don’t seat properly either unlss pumped up to 40psi then let down. Of course, I ain’t doing that post puncture out in the trail with a mini-pump!

Sorry Pimp, only just seen this. Yeah was a bummer and really missing fat, especially as 5 riding buddies now have them!

On the plus side, when the Fatty went back I ordered a Canyon Dude which should be with me in 4 weeks 🙂

Floaters are 20PSI max, I’d be worried taking them above that myself, especially if tubeless.

I’ve run mine with and without tubes, and do have a bit of a wobble, but then my non-on-one rims also have a bit of a flat sport where the rim is pinned, so it’s not the end of the world.
