I'm running Schwalbe Pro-Ones on Enve 4.5 AR rims. A fabulous combo EXCEPT the tire is very tight on the rim. I know a few folks with the same setup who were unable to get the tires unmounted while at a workbench, let alone roadside. However, with these levers I had no problem. They're very strong, and the tips are shaped just right to grab the tire bead without harming the tubeless tape. My other levers, Pedros and similar, were just too blunt and useless in this case.
I think if you're running regular tubed clinchers on alloy rims, you don't have to be choosy about your levers. But for tight tubeless, if you get a puncture that requires a roadside tube installation, these are the only tools I'd consider.
As to price which is cheaper, a set of these or a single Uber?
So as far as tire levers go, these are expensive but still a small expenditure at $18.00 here. I have carbon rims and like how these work with the rims. The tires were easier to get on and off with less worry about damage.
