Well it's worth a go ๐Ÿ˜‰

Lower rolling resistance, no pinch flats, what's not to like?

Shards of glass are what not to like.

Pinch flats on the road? With 100PSI? I don't think I've had one of those.

Never hit a pot hole, drain cover, kerb? Roadie tires are 1/3 the width and 3x the pressure, so pinch flat just as easily as mtb tires. If not easier seeing as theyr so thin.

I ran my commuter tubeless for a while (1.3 slicks), made bugger all difference other than rotational inertia TBH.

Ever tried to pump a 23C tube up to 100psi out of the tyre?

I've never pinch flatted on the road.

Would quite like to try road tubeless though. Not particularly fussed with conversions on the road, but if I had some Dura Ace or Ksyrium or Fulcrum wheels I'd give it a punt, a friend recently converted and raves about it. I use the tubed Hutchison Fusion tyres anyway, they seem good!

Busy changing to tubeless on the road bike. Rear is done, no probs. Front the tire needed a stretch with a tube first but will be tubeless by this weekend.

I'm use my Mavic CXP22 rims with stans 19mm tape, stans road valve and sealant with Hutchinsons Fusion 2 tubeless tires.

mehhh, i suspected a troll.

FWIW no more thorn punctures, no more pinch flats, whats not to like?

Ok roadies probably only flat once every 3000miles, but I'd still be tempted.

Simple problem!

Have you tried putting a road tubeless tyre back onto a road tubeless rim, with a tube inside? - like what you'd have to do if you got a puncture out on a ride...

Anyone who has, would tell you that road tubeless is NOT the future - in fact, its more hassle than riding Tubs.

Exactly what happened on my commute home last night. A car decided to muscle past, I hit a pothole and the rear wheel bounced a good foot into the air followed by the dreaded pppsssssttttt as the rear tyre deflates instantly. I thought about going tubeless with a set of Ultegra wheels but decided not to as I would had to have paid proper money for tyres. Starting to wish I had now.

Seems good so far - as Nick said I converted my Ksyrium ES wheels - only needed to buy a couple of Stans valves. Tyres (Hutchinson Tubeless Road) went up first time with a track pump. The rear has a couple of small knicks in it that may have been flats had it not been tubeless. Done about 700 miles on them so far.

Bit of Stan's sealant, with the likely size of holes in a road tyre (ie minute) you'd almost certainly get enough air in it to ride home.

Why does 100psi tubless give me the willies?

Dunno.

Interesting - I'd heard they weren't that great (and RR was high enough that you didn't get any RR advantage over running them tubeless compared to PR3s). Had just been waiting for Michelin to come out with road tubeless tyres. I presume nobody here is suicidal enough to put 100psi in a converted normal tyre?

Regarding pinch flats, I'd have thought you never get them on the road until last year when I managed two by hitting holes in the road I hadn't seen - it's not even like I'm all that fat!

5 pinch flats in one 40 mile ride last year had me looking at this as an option. Current bike is not really worth the upgrade though. A pair of conti-gatorskin tyres have reduced the incidence of flatting.

I'd read reports of RR not being great too. I am considering them however I'd prefer a removalable core latex tube +sealant as an idea for road racing. For general road riding I'm happy with my home made sealant tubes.

It seems that quite a few people are considering running road tubeless without sealant - which seems to defeat the point of it.

If you are running tubeless MTB you get loads more punctures on the road!

You don't need to be heavy aracer. I am no fatty but at 25mph hitting a decent sized pothole is going to test any tyre. And potholes seem to be in fashion on the roads of Britain.

I've converted an old set of Reynaolds Alta wheels to run Tubless and they are great - rolling resistance is better than the clinchers I had on before but not quite as good as Tubs - no flats so far in about 600 miles and they went up easier than the moutain bike tyres ! The best thing though has been the ride quality which has been noticeably better than the Conti GP's they replaced. Its particularly noticeable on those wheels though as they are a deep section rim and so very stiff. I don't think the benefits would be all that great on open Pro's or similar. The 25mm Hutch tubeless road tryes are crap though - slow and heavy.

I wouldn't run them without sealant either, for no other reason than the hutch tyres are not designed to run without sealant !

I want to run tubeless on my BMX!

A friend of mine did! DT RR1.1 rims, a few turns of electrical tape, Stan's valves and his normal GP4000 tyres! He didn't die.

Definitely not gonna try that myself though!

I rather struggle with defining 'good' road tyres, I've never crashed on them, I disposed of a pair after 18 months solid use (probably about 6000 miles or so) including 2 winters use when I got my first puncture. Replaced with another pair, which I've yet to flat. They're reasonably light, roll ok, go on and off the rims well enough. What more do you want from a road tyre!?

I run them and wouldn't go back to clinchers

[Fusion2s on Open Pros]

The RR comparisons tend to be made at 120psi, which is above what you'd run the tubeless at anyway. At 90-100psi they are faster and tougher than a tubed tyre IME. Some (most?) of the people who aren't fans of tubeless haven't even tried them.

but that's nothing like a road bike with 23/25c's
