The Schwalbe Rock Razor is one fast running tyre. It's semi slick design lets you fly down the trail and fly up the trail with is minimalistic rolling resistance. The side tread is nothing short of awesome and, much like with the Magic Mary, you can lean the tire in and hold the bike firmly on the side tread. Once you get used to the tire's excellent grip when leaning the bike into corners, you can easily forget that it is still a semi slick.
