Discussion: Do they make tubeless or so...

Do they make tubeless or solid run flats for road bikes? I've heard of folks switching to them for mtb, but not road, so not sure if that's a thing or not.

I was curious but I haven't seen too much on it. If the marathon plusses don't do the trick, I will pioneer the field with guidance from tubeless cx setups Heidi's done - tire is roughly the same and efficiency is important, so perhaps close enough.

Not nearly as many tubeless road setups yet due to the high pressures demanded by road tires. That being said, you could go tubeless with a 33cc CX "slick" and be just as happy and have a much more comfortable commute.

What pressure do you run for tubeless cx?

Depends on terrain. This past weekend at the Trek CX Cup I ran 22 psi. On gravel rides that include pavement i'll run up to 40 psi sometimes. Personal preference like most things. Many of the cx tires can go up to 50 - 60. Check their rating. The rim their mounted on makes a big difference also. I've blown a tire off a Stan's Iron Cross rim at 44 psi when I accidentally put too much air in while doing the initial seal (early lesson learned!). There's a lot of info out there regarding going tubeless for commuting. Check it out.
