I just don't get road tubeless. It's like trying to one up standard clinchers but is still lame compared to tubulars, imo.
Besides, the tires are just as expensive as tubulars... heavier and worse ride quality.
here's a good pro/con list
Road Tubeless Tire Benefits & Disadvantages | Bicycling Magazine
I stopped using sealant. It's ok when new and does work but on a high pressure road tire, it can also spray like a mofo before it seals.
That sealant ruins lycra. It also dries out fairly quickly and turns into another maintenance item.
It's a hassle and I never felt needed since I stopped using it. I still have a bottle of it in the garage.
Tubulars are easy. It is intimidating to newbies, but once you learn how to use them it is easy and the payoff is great.
Anyway, without further derailing the conversation, I would jump on those Zipps.
Tubulars are safe for crits and reap the rewards of lightweight and tubular comfort.
btw, tubulars feel and handle great because it is naturally a perfect circle in cross-section.
When you corner, it's still a perfect circle.
Clinchers are a U shape.
