I thought I should clarify the intended application for the BestRest BeadBrakR.
There's many ways to "break the bead". You can use a a car jack underneath a car, you can use a spade, you can use a common C-clamp, you can use a piece of timber, you can use a clamping device of some sort, you can use a dedicated tire machine. They all have their place and they all do the job if they're handy.
But....when you're out in the middle of nowhere these things are often in short supply. And you still need to carry a set of tire irons to get the rest of the job done.
To my knowledge, there's only ONE device that incorporates BOTH a bead breaker, AND a set of tire irons, AND is small enough to carry on the bike.
That device is the BestRest BeadBrakR. It does it all.
