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...Read more
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.
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. And the 4-pot brakes provide consistent and reliable stopping power.Read less
The 6061 aluminium tubing is durable, light, low maintenance and stiff.
Clean lines and tidy cables thanks to internal downtube routing. Frontier also incorporates routing for a dropper seat post.
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.
The Frontier frame is designed around bolt through Boost 148mm rear spacing providing the benefit of stronger, stiffer and more efficient wheels. Seatstay mounted disc brake for clean lines and damage protection.
Fit 2 bottles in their standard location or run your downtube bottle cage a little lower to clear a bikepacking frame bag. Plus there’s an extra bottle cage mount under the downtube.
