The Oracle Ridge trail is a trail that brims with backstories and history as it is one of the earliest known routes to the top of the iconic Mt. Lemmon. A beautiful gravel climb connecting to the backside of Mount Lemmon before descending onto pavement, it passes through long-abandoned and freshly-laid mining roads and bulldozer paths. The trail also happens to be one of Lael Wilcox’s favourite routes and Renee Herse worked with the bikepacking legend to develop this tire.
What Rene Herse sought to do with the Oracle Ridge is create a bike tire that can balance the grip of a knobby tire without compromising on speed. The end result was a road-centric knobby that is still dirt-ready. 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.
The Oracle Ridge features patented noise cancellation technology which works when the staggered tread blocks create overlapping noise frequencies that partially cancel each other. The Oracle Ridge’s speed, grip and lack of noise almost make you forget you’re riding a knobby – until you hit some loose or muddy ground and appreciate the extra grip. On the gravel climb, this tire grips tenaciously thanks to its large 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.
