I've read that tubeless tires/rims are the closest to the supple ride of tubulars. But it's far from perfected.
What does one do about types of flats?
The lack of tubes will be a good thing. And I look forward to trying once it's mainstream. I couldn't live with the hassles of tubulars back in the late 70s/early 80s...and still wouldn't think of running them.
But that's me.
