Tubeless Tyres Advice needed

anthonyv

I have now decided to replace my wheelset with Fulcrum 1's.... but have the option nof the tradtional clincher version of the tubeless/clincher 2-way fit version?

Any experuience out there with the tubeless version? How do you repair a flat on the road?

Thanks

I run tubeless and I'm a big fan. Good RR, very supple, good grip @ 90psi. Not had a puncture yet so can't comment on that directly but they deflate fine so fitting a tube at the roadside would be no different to a normal tyre I suspect.

I'm not going back, and if you have tubeless rims then I'd advise you to at least give them a go and make your own mind up. Tyres are a bit more cash than a regular tyre and tube but not by much.

Fusion 2's feel amazing to ride. Have however had several punctures since roads where I do a lot of my riding were re-surfaced poorly. Stan's sealed them all with only a small amount of pressure lost.

I would definitely go for tubeless-specific rims given the option, my non-tubeless Fulcrum 5 wheel works fine apart from it being ludicrously hard to fit the tight tubeless tire beads on. The 2-way fit ones have a groove in the rim bed to help.

Think the concept is spot on but suspect that someone like Michelin could come up with much better tires than the Hutchinsons for it.

Five years on and still nothing...

why are Michelin dragging their feet? It's not like they don't have experience with tubeless as they do loads of mtb tyres.

in fact, why are pretty all the tyre companies doing likewise?

I accept that roadies take a while to get hold of techy stuff but c'mon.

I'd go for it, having converted my mtb, i'm planning on doing my cx bike possibly for the winter, then doing it again with new tyres for the summer.

You don't need to have tubeless rims to run tubeless - Stan's tape does a pretty good job on most rims. You can also run regular tyres with tubless rims. I'll probably try some next spring - the Intense for Flanders and Paris-Roubaix sportives

Eeerm on a road bike i'd be concerned about the quality of the rim gripping onto the tyre. A proper UST rim will make life a lot easier, ideally with a tubeless ready tyre and some sealant.

I run Fusion2s on Open Pros, with Stans tape. No problem whatsoever.

I'm sure a UST rim makes it easier but a standard rim works fine, trust me. I've run this setup for about 6 months now, including foreign trips and dodgy road surfaces, and I've not experienced any issues at all. No loss of pressure or anything.

Have you ever punctured and rolled it off the rim.?

I run ghetto setup atm, so am just using a innertube as a rim-strip. I cannot remember how energy scales with the volume and pressure of a gas.

Presumably because a 23 is about 1/4 volume of a mtb tyre, and the pressure to blow of my tubeless setup was 55psi, let's say 50psi for simplicity. Then a road bike tire should do the same at 200psi, is that about the right idea?

No, I've not had a puncture on the Fusion2s (yet).

I run tubeless on the mtb too (and I've got a 456... 8) ) - ghetto on the front with a standard tyre and UST on the rear, with a taped rim - and my feeling is that the Fusion2s are very secure on the rim. I've had them up to 130psi and they never looked even close to popping off. As for proper blowouts, I suspect if they did deflate quickly then they'd behave in a similar way to a standard tyre. Perhaps even more secure actually. TBH I don't really think about these things. I've had big blowouts in the past and it was no big deal.
