Oracle Ridge Tires in Stock

Oracle Ridge Tires in Stock

Lael Wilcox has been enjoying her Oracle Ridge prototypes all summer in Alaska. Now you can get a set for your bike, too. The new tires are now in stock with Standard, Extralight and Endurance casings.

At 48 mm wide, the 700C Oracle Ridges are designed for the latest generation of all-road bikes, like Lael’s Specialized Diverge. They also are a perfect fit on Salsa’s current-generation Warbirds (we’ve tried it!) and many other bikes. The Oracle Ridge pushes the development of our dual-purpose knobbies one step further. Since this is a road-oriented tire – for gravel and pavement – we’ve spaced the knobs a little closer for an even smoother, faster ride. And our noise cancellation technology makes our latest knobbies almost as quiet as slick tires.

Lael is a great tire tester: She puts lots of miles on the tires quickly, and she rides in all kinds of conditions. She’s already on her second set, and she reports: “The Oracle Ridge are extremely fast— they almost feel like slicks, with great traction.” She also found that they work great in mud – we’ve designed the tread pattern so it self-cleans as the tire rotates.

Some people have noticed that we don’t offer a 700C x 48 mm with our all-road tread pattern… We have no current plans to make one because we think that, once you try these, you may not see the need for anything smoother and faster. (If you do want a smooth tire, we do offer the 44 mm Snoqualmie Pass.)

Also new is the Endurance version of our iconic Babyshoe Pass 650B x 42 mm. Like most of our wide tires (and all Endurance versions), it’s tubeless-compatible. The Babyshoe Pass was right at the start of the all-road revolution, and it still is my favorite tire for a bike that sees as much use on pavement as on gravel.

When we develop new tires, we always think of how they’ll be used. Lael’s rides in Alaska are inspirational. We can’t wait to see where others take our new tires.

    What’s the likelyhood that all the latest development in the dual purpose tires, like tighter knob spacing and noise reduction, will make it back to the 650b versions at some point? I’m guessing not much, as the molds for those tires already exist, but thought I’d ask.

      Tire molds don’t last forever, and we’re also always weighing the costs and benefits of incorporating new technology into existing products. So while it’s not imminent, it’ll happen at some point. So no need to hold off on a tire purchase, but once your new set wears out, there may be ‘new and improved’ ones to replace them.

    Hi Jan!
    I’ve read a recent post of yours regarding hooked vs hookless rim design and the compatibility with Rene Herse tires. I’m also considering getting a new par of wheels for the Oracle Ridges i am expecting in the post any day now 🙂
    Could you comment a bit regarding what happens to the tire after a flat, specifically what helps the tire stay on the rim and avoid separation from the rim which would be significantly more dangerous for the rider?
    Is it a function of hooked/hookless rim design? Are there other concerns related to the tire and/or operating pressure and/or tire/rim match?
    I do prefer tubes lately due to not having to deal with the hassle of sealant…

      What keeps the tire on the rim after a flat isn’t the hook. (The hook helps at high pressure, not low pressure.) It’s basically the rim bed shape. On a ‘classic’ rim, the well is a simple U-shape, and the bead automatically slides down toward the center and becomes slack when the air pressure is released. That makes tire mounting easier, but it also means that the tire can come off when it loses its air. Most classic rims were dimensioned so that the slack of the bead wasn’t too great, and the tire _usually_ didn’t come off, but some had overly deep wells that were truly dangerous if you had a flat.

      Tubeless-ready rims have a flat shelf on which the bead sits. Even after you deflate the tire, you need to push the bead off that shelf into the well. This makes mounting tires a bit harder (you just need to do that extra step), but it usually prevents the tire from coming off even if it loses all its air pressure. Of course, if you continue pedaling without air, the tire will eventually come off even with a tubeless-ready rim – or you’ll crash because the tire has almost zero stiffness.

      There’s another concern, and that is the sidewall height (G height). There are some rims with very low G height, which not only makes it easier to blow off the tire, but it also makes it easier for the tire to come off the rim after a flat.

    Do your knobby tires use the same tread compound as your (almost) slick tires?

    Also with the tread compound(s) how have you prioritized the following characteristics?
    * dry grip
    * wet grip
    * rolling resistance
    * tread wear
    * cut/puncture resistance
    * anything else

      The exact specs of our tires are proprietary. We optimize all factors as much as possible. Fortunately, the latest rubber compounds no longer force you to choose between grip and tread wear, as older ones did. The ‘wet-weather’ compounds that the bike industry has offered in the past usually offered less grip than the standard ones, so we’ve steered clear of them. I think you’ll find that Rene Herse tires grip as well or better, wet or dry, as/than any other bike tire. Our testing has shown that tread rubber has only very little effect on rolling resistance and puncture resistance compared to the casing.
