Tubeless is back and without much fanfare. And, just like gravel, it’s being driven by consumer demand, v a push from manufacturers. There’s not a bike I’m riding that isn’t with a tubeless wheelset on it and that’s because of high volume, low pressure (never more than 32), and much, much better tires. If you care less about riding a road bike on dirt, you should care about how good new tires like the Schwalbe One are.
In the short history of tubeless, what happened was, Shimano gave up the market and that includes their tech; they unofficially are allowing anyone to use what was once heralded as UST, and do so with a new rim profile that secures the tire, preventing a blow off.
If you used road tubeless back then, it sucked…because the tire would only seal at the lower, limp-home PSIs, and if you did flat, the tire would fly right off the rim (happened to me twice).
Well, with about zero fanfare, tubeless is back.
For road. It’s what we’re riding.

If you’re not quite ready to upgrade to a gravel, adventure bike, these tires will open up new roads for you, for sure. What’s missing and I’m not sure why is any mention of sealant and I’m not running any pressures near 115 PSI, but good to know I can do that, I guess.
Also see my Tangente post here from when they first launched. The remind me of the old Open Corsas, new, and improved with Zipp graphics.…
