A road-centric knobby? A dirt-ready road tire? You decide! At 48 mm wide, the Oracle Ridge hits the sweet spot between narrow gravel tire (38 mm) and mountain bike volume (55 mm) – ideal for the latest generation of gravel and all-road bikes.

We’ve developed the Oracle Ridge together with bikepacking legend Lael Wilcox, and we’ve named it after one of Lael’s favorite routes: Oracle Ridge is a beautiful gravel climb outside Tucson, AZ, which connects to the backside of Mount Lemmon for an ultra-fast descent on pavement.

On the gravel climb, this tire grips tenaciously thanks to its tall and widely spaced knobs. On the descent, it corners like a slick thanks to its large and strategically placed knobs that don’t squirm and always put the same amount of rubber on the road.

The Oracle Ridge features our noise cancellation technology: The staggered tread blocks create overlapping noise frequencies that partially cancel each other. The Oracle Ridge’s speed, grip and lack of noise make you forget you’re riding a knobby – until you hit some loose or muddy ground and appreciate the extra grip.

The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse.

The Oracle Ridge is tubeless-compatible.
