Tubeless tyres

[dandare]

Anyone on here tried tubeless tyres? I know the choice is a bit limited. in a perfect world I would always run tubs but not very practical on a daily basis. Tubeless seems to cross that divide between clinchers and tubs.

Can't see how it crosses the divide between the two. Tubs have inner tubes, just that they are integrated into the tyre as one. As I understand it tubeless does away with the inner tube. Perhaps somebody who is using them could give us first hand experiences.

Well that is what I was hoping for, someone who has tried them. To me they do bridge the gap, having the safety of tubs with the conveniance of clinchers.

I have, they've been on my "best bike" for about 8 months done about 800 miles at a guess . Schwalbe Ultremo's on Zonda 2 way fit wheels. Can't say I've noticed much of a performance difference from the normal Ultremo's they replaced.
Suffered one puncture at the end of the Ride london 86, something puntured the tyre it deflated to about 40 psi then the sealant sealed the hole. I topped it up with a co2 and forgot about it.
I was getting the bike ready for a 170mile ride last weekend and thought I'd take that tyre off and have a look inside, dried the inside put a patch over the previous puncture, put it back on some fresh sealant in and it was fine, it probably would have been ok for the ride anyway.
I've got two mtb's with tubeless and not had any problems with them, ordering a cyclocross bike this week and I'll run that tubeless.
I like them but still have to carry two tubes and co2 just in case. You still might have to stop and top up the pressure if the sealant seals a puncture and if it doesn't put a tube in.
My bike came with 2way fit rims so thought I might as well try the tubeless tyres but I wouldn't replace a set of wheels just to go tubeless.
Tyre choice is a bit limited but I like Ultremo's so doesn't matter too much.
I've just bought a big bottle of sealant with the intention of replacing the stuff in the tyres as it apparently dries out over time.

Thanks for that @goody I am interested to know how you apply the sealant. Sounds effective.

Tubeless valves with removable cores and use a syringe to squirt it in, or pour it in the gap beween tyre and rim before putting the last bit of the tyre on.

After many years of good service from my Easton wheels I feel like a change. Looking at the Campag shamals. There is not a lot of difference in weight or price for the 2way.
I do like the Ultremos so was just wondering which way to go.

I am running Schwalbe One tubeless on Fulcrum Zeros, before that I did 1200 miles on Hutchinson Fusion 3's I switched as I had a big tear in one of the Hutchinson the gunk got me home. Punctures if they are big can be terminal, but my view is anything that cannot self seal you wouldn't be able to stick a tube in on a normal clincher anyway. I could have repaired the Hutchinson's but the One had been launched so wanted to give them a try.

The Hutch's were a bit softer feel on the road the One's run pretty much like a Conti GP. I am running 23's which are a tough to get on, well they were for me. Someone I know is running 25's and they seem a lot easier to go on, but he is running them on a non specific tubeless wheel which might also make them easier to get on.

There is no way I could get a tube in at the roadside without damaging it, so I am relying on the gunk and Co2 if it ever completely deflates.

I lose 10/15 psi over 24/48 hours so they need more regular topping up, but you can run them at much lower psi without the risk of pinch flats.

Not sure they offer any huge performance advantage.

Will I replace these with another set of tubeless? Undecided I quite like the security of a couple of tubes with me and the knowledge I can sort most problems out at the roadside.

Ultremo's have been discontinued in tubeless and replaced with the One. http://www.schwalbe.com/gb/road-reader/schwalbe-one.html

oh and if the hole is big enough they are bloody messy! Took a minute or two to seal up the front one once and it was a fountain on every rotation!

Not run tubeless on the road bike, but had one on for 2 years on the mtb, just took it off there are signs of sealing holes in a couple of places but I don't recall the punctures it must have been a near instant seal, the sealant was still liquid & had not dried out, but I had topped it up previously, this tryre was set up using a 20" inner tube stretched & slit down the centre then the excess trimmed off when the tyre fitted, (known as Ghetto fitting) I was having trouble infating the tyre with just rim tape, these are Bontrager tubeless ready rims, I have just built up some wheels with Stans Crest rims and the tyres pumped up 1st time with a track pump, just Stans rim tape and a tubless valve on these rims.

 

[Andrew_P]

Oh I forgot the main reason why I switched! I had a massive blow out and came off and dislocated and fractured my shoulder, the huge advantage for me was the extra security that massive and fast deflations are almost impossible, in fact I reckon they would be ok running flat at least to bring you to a controlled stop, there is no way they would come off the rim like a clincher & tube

Managed to get a pair of Ultremos plus the sealant and lube. Not a ridiculous price, £65.00. Just got to decide on which wheels to get now.
