Quote from aikigreg on Jun 30th, 2015, 7:34pm:Since February. They're flo 30 rims and schwalbe one tubeless tires. I can't speak to weight, rolling resistance, or any of that, but being able to run them 10-20 pounds less without worrying about flats makes it seem a lot more cushy. Just carry a tube in case you get a cut that won't seal, and you're good to go. Everyone tells me the orange sealant is the best, but I haven't had to use it yet. I've definitely run over stuff that would have flatted me, but the cuts sealed well.
Greg, I assume you're running sealant of some kind in those Schwalbe's...which one, the Schwalbe blue? Also, how are you managing the efficacy of the sealant? I've been doing more reading on the subject...for maintenance, some recommend poking a hole in the tire with a pin every month or so and observing the result. If it seals right away, all is well. If it seals slowly they say to add more sealant. Presumably at some point a person would dismount the tire and peel out the cured sealant, if he was concerned about the added weight of it.
I'm not confident I can trust everything that I've read on the subject, since the internet is filled with nut jobs, people expressing ill informed opinions as facts, and people trying to sell something. I prefer to benefit from the real world experience of people I trust...
