The radder version of WTB's famed Riddler tread pattern, the Raddler combines the supple traction of a high-volume gravel tire with the rolling efficiency of a short-knob tread design. The minimalistic centerline allows you to maximize the output of every pedal stroke, while toothy outer knobs provide cornering confidence that refuses to let up. The time-tested Raddler is an excellent choice for unpredictable roads or trails where traction is key, but efficiency is of utmost importance.
1 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.
2 SIPED OUTER KNOBS
It's not often you see knob siping on a gravel tire, but Raddler isn't designed to be like every other tire. Sipes run the full length of each side knob to double their working edges and drastically improve cornering traction in both loose and wet conditions.
3 EXTENDED TREAD LIFE
Slightly taller overall knob height throughout the tread compared to the original Riddler tire, which increases longevity without a noticeable change in rolling efficiency. Taller knobs pair well with it radder, hard-charging usage.
4 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.
