Downhill, enduro, all mountain, it doesn't matter if you need grip, durability, and the confidence to push it, shoe up with Schwalbe's Magic Mary 27. 5in Tire. Just look at it: giant blocky tread eats technical trails and loose corners for lunch, and the tough bead locks onto your rim like a grappling hook onto a castle wall. Schwalbe serves up the Mary in two versions, a SnakeSkin and a SuperG. SnakeSkin's made with Schwalbe's original puncture resistant TrailStar ruber, while the SuperG loads up with a bombproof VertStar compound that is tough enough to ride down trails made of nails and broken glass don't actually do that, though.
