    The Aurora: our all-new road disc model

    November 08, 2016 2 Comments

    No. 22 Aurora Road Disc Titanium

    It's not every day that we get to announce a new model, which made our launch of the Aurora at the recent Philly Bike Expo even more special. Blending the sublime handling of our Great Divide Disc with the smooth ride quality and increased stiffness under power of the Reactor, the Aurora has been one of the most anticipated bikes we've ever released.

    Up front, the Aurora uses a tapered head tube with an integrated headset, shrink-wrapped around the thru-axle tapered steerer carbon road fork. Taking a page from the Reactor's playbook, the Aurora features a CNC-engraved head tube "badge", saving a few grams over our conventional solid titanium badges.

    No. 22 Aurora Road Disc Titanium

    The carbon seat mast with our cast titanium topper matches a velvety-smooth ride quality to the increased stiffness of the Aurora's larger down tube and top tube. Together with standard thru axles front and rear, the Aurora provides a reassuringly solid platform for hard cornering and uphill attacks.

    No. 22 Aurora Road Disc Titanium

    Tire clearance is generous for a pure road frame at 30mm front and rear.

    Full details and studio images will follow on the website shortly, but in the meantime feel free to email us with any questions.
