    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. With full rack mounts at the back, Frontier is an adaptable off-road explorer.

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

    At a glance

    • Shimano Deore M6100 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 Deore

    Shimano drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. Shimano's new microspline hub means that you can run a 10 tooth cassette for a huge gear range. The new EV shifters and brakes provide loads of adjustment to get the perfect position as well as a rock-solid feel on the bars.

    Features

    Tuned for all-round capability

    Built for a balance of cross country efficiency and trail centre capability. A favourite with bikepackers looking for all-day comfort and performance.

    Light and clean

    Clean lines thanks to internal cable routing. Frontier also incorporates routing for a dropper seat post. The 6061 aluminium tubing is durable, light, low maintenance and stiff.

    Wider tyres. More grip.

    Extra width between the chainstays gives you the choice of running 27.5+ tyres up to 3 inches or 29 inch tyres up to 2.5 inches.

    Made for stronger wheels

    Designed around bolt through Boost 148mm rear spacing providing the benefit of stronger, stiffer and more efficient wheels.

    Wilderness trail features

    Chainstay mounted disc brakes. And triple bottle mounts.
