I was reminded that I was going to post my experiences/thoughts regrading road tubeless. So here we go:

Given that virtually all cars and motorcycles have gotten away from tubes you'd have to think that, barring the UCI's interference, we're eventually going to end up there. Road tubeless is no longer "new" tech, and I can only think that the small number of tires and tubeless ready wheels is the only reason the technology hasn't wiped tubes off the map.

Quick pros and cons vs. conventional clinchers:

Pro:

No pinch flats
Less flats if you use sealant
Less catastrophic flats (especially if you use sealant)
Better ride for clinchers than latex tubes
Better rolling resistance with the new tires
No weight penalty

Con:

Harder/messier to mount
Less brand selection (Hutchinson has 4 models so tire selection isn't really the right term to use)
Requires a kit for non-tubeless rims

And vs. Tubulars:

Pro:

Easier to mount (hugely quicker)
Easier to change flats
No pinch flats

Con:

Slight weight penalty
Less wheel selection


I've been running Shimano Ultegra and Dura Ace tubeless ready wheels for a couple of years now with a variety of Hutchinson Fusions, their Atom race tire, and I just tried the Intensive 25c training tire as "everyday" trainers. For the really bad cut ups I carry a tube and a tire boot, no different than if I was using a tube, though my spare tube didn't see use for nearly 12 months.

I liked tubeless enough that last year I set up my wheel used Token C50 wheels with a Stan's kit and some Fusion3's for the Chico Stage Race which has a long section of gravel. It was pretty much the bomb.

So I'm sold enough to be setting up a set of crit wheels for next season. If they work as expected I'll be moving away from tubulars for most of my race wheels except for track and my rear TT disc.
