Whats up with that? Just saw some nice dura ace tubeless wheels on bonktown...What are pros cons of tubeless?

DanMartin

Pros: Same as a clincher, just without the inner tubes. Using sealants prevents flats, no more pinched tubes. Allows lower air pressures for flat prevention, and smoother ride with increased grip.

Cons: Limited available options for wheels & tires.

I've been using them for two years, they are great, zero downside for me. I really don't understand why clinchers with inner tubes are still produced. It's going to take Mavic coming out with a tubeless wheel, & Michelin a tubeless tire to finally make the conversion the standard. It may not happen because people are stuck in their ways.

what kind of pressure do you run in these types of wheels? Also, I assume these require some special tires? Or not? Do the major tire producers make tires for these types of wheels? Thanks

Ok, stop right there.

Come back if you still have questions.

The reason they aren't used more is most wheel manufacturers aren't convinced they work, the choice of tires is very limited and none approach the quality of ones like Mich Pro Race 3 or Conti GP4000s, and some people have problems with the sealants (do a search and you'll read about some of the issues).

90-100lbs. But feels like 120lbs to me. Yes, they require specific "tubeless" tires. Hutchinson is the only mfr. that I know of. Specialized offers them, but they are probably re-branded Hutchinsons.

bontrager makes them now as well but they are just rebranded hutchinsons as well. I have been riding them for a few months now and I love them. I run about 100psi when i used to have to run 115psi with tubes. They roll a lot better and give you a more comfy ride with our the risk of a pinch flat. There are a few companies starting to develop a road tubeless tire such as kenda but it may take awhile as they need to first make a bead that won't stretch which means it will be carbon and then they need to get the tire diameter right so it fits on the rim tight but not to tight or to loose. It might take a few years for it to catch on like the standard it has become for mountain biking. With mountain biking you are maybe running 35psi but when you run a road tire tubeless that psi is greatly increased which increases its chance to fail, such as blowing off the rim. That is why they are taking so much time to develop tubeless specific tires.

I have been running Hutchinson Fusion 3 tires at 90 to 95 PSI on Fulcrum Zero's for about a season know and have been very impressed by the performance and ride quality. If they roll and slower than GP4000's or Pro3's I sure don't notice it. Only downside for me is they are a ***** to mount the tires.

And nobody should really have much of a problem with the sealant. It's like anything else: figure out how to use it CORRECTLY, and it's a cinch. E.g., Problem: dried sealant makes reinstallation a booger. Fix: clean up the sealant before it dries.

I've ridden about 5K miles on them this year (2nd set of tires now). No issues. Only one flat. Check the archives for what I've written before -- not that I'm an expert, but I don't have time this afternoon to repeat the same info.

I like them a lot.
