The Riddler 700 is the ideal gravel or CX tyre for fierce competitors. Available in two different widths, depending on whether swiftness or confidence is most important to your race, it pairs short, regular centre knobs that limit drag and maximise efficiency with larger outer knobs for snappy cornering.

Opt for the 37mm width if you want to navigate the cyclocross loop as rapidly as possible, or choose 45mm if you’re planning to be out all day, or even overnight, and want to negotiate gravel tracks with maximum traction and peace of mind.

Either way, WTB’s Tubeless Compatible System will give you the durability you need to ride with less pressure, for improved grip and comfort, while the option for SG2 reinforcement will virtually eliminate any chance of flats slowing you down. For those really counting the grams, there’s also a chance to select tan sidewalls over black, for a marginally lighter tyre with a touch of nostalgic style.

Named Gran Fondo’s “Best in Test” and BikeRumor’s “Editor’s Choice Gravel”, the Riddler 700 will offer you efficient, speedy passage over pavement and gravel alike, making it an excellent racing tyre that will save your legs by making the most of every watt.
