What tire should you use when hitting a mixture of trails, gravel, dirt roads, and tarmac? The answer to that riddle lies here. The WTB Riddler is the perfect choice for high speeds on a variety of terrain. Named after WTB athlete Nathan Riddle, the Riddler is a great blend of stability and speed. WTB took this proven mountain bike tire tread pattern and shrunk it down for the cross/gravel crowd. Densely packed, low-centered tread provides fast straight-line speed that you can carry into the corners, and supported toothy side knobs bite hard so you can rail them with confidence. The Dual DNA rubber compound optimizes efficiency, traction and durability. The Riddler is a great choice for those riders who race cyclocross or just want to hit varied terrain without boundaries. Available in 37mm or 45mm wide versions.
