Built for unfaltering speed through a wide range of conditions, the Riddler delivers swift efficiency for riders who value traction but still prioritize leading the pack at the end of a long ride. Looking for a gravel tread that keeps your legs on their game for hours on end while also accommodating longer dirt tours with ease? The Riddler is equally at home on your local cyclocross course or gravel B-road.

Feature
• SEMI-SLICK TREAD
Shorter center knobs cut down on rolling resistance while still providing ample bite for out-of-the-saddle pedaling. Increased outer knob height allows them to bite in the earlier phases of cornering and therefore provide the traction you need on loose gravel roads.

• EFFICIENT KNOB SPACING
Tightly spaced knobs throughout the the tread keep the Riddler 700 rolling quickly and efficiently across the whole spectrum of riding conditions. Uninterupted knobs ensure you get the most out of every single watt you're able to crank out.

• TWO WIDTHS, MANY USES
The Riddler 700 is available in 37 and 45mm widths. Riddler 37 is the go-fast option for those who are in it to win it on their CX or gravel bikes. Riddler 45 is the go-confidently choice for long gravel rides or bikepacking overnights. Whichever width you choose, the Riddler 700 is often considered the set-it-and-forget-it gravel tire in the WTB line.

• TUBELESS COMPATIBLE
TCS (Tubeless Compatible System) is WTB's standardized tubeless system. These tires feature a TCS tubeless casing, which nearly eliminates flats and allows lower tire pressures to improve traction and comfort over a traditional tube-type tire.

• AVAILABLE WITH SG2 PUNCTURE PROTECTION
SG2 is our unique puncture protection technology that provides bead-to-bead coverage to ensure both the tread and sidewall are protected from slashes and punctures. The nylon fibers within SG2 feature a uniquely flat profile, which reduces the amount of rubber between fibers. Improving the fiber-to-rubber ratio increases puncture resistance, reduces weight and improves the overall liveliness of a tire. While SG2 is primarily a puncture protection layer, its tightly woven fibers also improve air retention to better maintain pressure between rides.

• BLACK OR TAN SIDEWALLS
It's nice to have options, which is why most of our gravel tires are available with either black or tan sidewalls. Traditional black sidewalls tend to blend in with the components and wheels of a bike and may look sleeker in the eyes of some riders. WTB tanwall tires blend retroesque looks with modern technology to create an iconic look that has become synonymous with high-performance gravel. Looks aside, gram counters may choose our tan tires because the compounds used to make them are slightly lighter than those used to manufacture black sidewalls.
