        Frontier is our multi-activity hardtail mountain bike. Ride hard at the trail centre, load it up for a midweek bikepacking trip, pocket your passport and continue around the world. Frontier is an adaptable off-road explorer.

        The geometry is for long day comfort but it’s no slouch.

        At a glance

        • SRAM SX Eagle 12-speed groupset
        • Rockshox Recon Silver RL fork
        • Sonder Nova 27.5 / 29" XC wheelset
        • 6061 aluminium frame

        The 6061 aluminium frame provides a durable and stiff chassis giving a responsive kick as you demand power when the slope steepens or enjoy feedback and precision through the corners.

        Available as a fully rigid or with 100mm suspension fork. Set it up for XC race speed or for all day big mile comfort.

        Tyre clearance gives you the choice of 27.5+ or 29in wheelsets. Bolt through 148mm boost rear spacing provides the benefit of stronger, stiffer and more efficient wheels.

        Why SX Eagle?

        SRAM Eagle drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. Its 1x drivetrain is built to be lightweight, strong and intuitive, with the gear range to ride on any terrain.

        SX Eagle provides the same Eagle performance benefits as NX Eagle, but at a lower price point. The main differences stem from the choice of materials and finish options, but functionally SX is fully compatible with SRAMs Eagle groupset.

        Your actual build date will depend on additional components you specify and from receipt of full payment. For any queries contact our Sonder team on +44 1773 417006.
