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 and multiple boss mounts on the fork, Frontier is an adaptable off-road explorer.
The geometry is for long day comfort but it’s no slouch.
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.

Internal Cable Routing
Clean lines and tidy cables thanks to internal downtube routing. Frontier also incorporates routing for a dropper seat post.
Wide Tyre Clearance
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.
Boost Axle Width
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.
Triple Bottle Cage Mounts
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.
Pannier Rack Mount
Seat clamp mounted pannier attachment points make fitting a rack easier and keep pannier rack rails free from twisting and warping.
