Tight enough tread spacing for high speed, drag-free onslaughts, yet blocky and tall enough to really dig in when it comes time to slam on the brakes. A rounded profile and staggered, supportive side knobs keep clamoring for traction even as the trail loses its camber. Most often used as a rear tire, the Trail Boss also keeps the front in check on hardpack trails. Want to go out and own it? Be the Trail Boss.

You need a tire that keeps your legs on their game for hours on end, provides tenacious grip in the corners, allows you to drop your buddies off the start, while remaining composed when leaned over through the first turn. Luckily, WTB has made the ultimate tire for you. Aggressive cornering knobs meet a fast centerline, making for a tire that carries speed into the turns yet corners like it means it. Roadesque enough in appearance, the Riddler 37c is just as ready for the local cross course as it is spinning down an empty gravel B-road. The 45c corners with confidence on hard surfaces while still sinking its teeth deep into your favorite trails. Incredibly versatile in a what-can't-it-do type of size, this tire breathes capability when mounted to any drop bar bike.
