  • 6061 aluminium frame
  • Set up as an XC for speed or relaxed for comfort and performance
  • Rockshox Recon suspension forks

  • Bolt through boost 148mm rear spacing
  • Rear mudguard and pannier rack mounts
  • 650b+ and 29” wheel size compatible frame

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.

Features

Aluminium Frame

The 6061 aluminium tubing is durable, light, low maintenance and stiff.

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.
