Features:

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. Uninterrupted 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.
