Allen F.wrote a review of Schwalbe Pro One Tire - Tubeless on March 9, 2019
Familiarity: I've used it several times
I've had two separate sets of these (25s and 28s). Both are super smooth and if you're riding tubeless, you probably don't need me to tell you how awesome it is. If you haven't made the switch to tubeless, it's time.
Mounting was pretty difficult, though. For the 28s, after wresting with them for most of an afternoon using a Specialized AirBlast, I finally took them to the LBS and paid the guy to mount them. Even he had trouble getting them on my Qurano 60s. After watching him struggle with the 28s, when I swapped them for my current 25s, I used my own compressor and ended up taking the presta chuck off the hose altogether and just rammed the hose directly onto the core-less valve. Holding the hose in place, I blasted the tire at 140psi. Once the bead popped into place, I covered the valve with my thumb, then had to Indiana Jones the valve core back in before the tires deflated and lost the bead. It took several tries to get it, my hands were sore and my thumbs were coated in sealant, but I got it working and saved a trip to the LBS. Compared to the videos on how to install tubeless tires, these took a lot more effort. Other wheels might be less challenging, I haven't tried these on another set to know.
I do love the ride, though.
