Description

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.

At a glance
  • 6061 aluminium frame and rigid Boost fork
  • Relaxed riding position for comfort and performance
  • Hydraulic disk brakes compatible
  • Bolt through Boost 148mm rear spacing
  • Rear mudguard and pannier rack mounts
  • 27.5+ and 29” wheel size compatible

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 Boost 148mm rear spacing provides the benefit of stronger, stiffer and more efficient wheels.

A First Look at the Sonder Frontier

It is a bike that will likely tick many boxes for anyone planning multi-day rides, without first returning home for their tea.

Active Traveller Review the Sonder Frontier

This cracking value and rock solid machine from Sonder is just crying out to be loaded up and taken to the horizon.

Andy McCandlish
CyclingLife Review the Sonder Frontier

Giving several centimeters of squish, their suspension-like characteristics help the Frontier float over rough terrain. With big handlebars, an upright position, and loads of stand-over, the Frontier is great for roistering about on, and could certainly serve as a regular mountain bike.

Frontier Makes Red Bulls List of Best Bikepacking Bikes 2020

Arguably one of the best value bikes in this selection, Sonder’s Frontier Rigid is a 27.5” (or 29” compatible) mountain bike, armed with a wide-ranging SRAM SX Eagle 12-speed chainset. You’ll find plenty of mounting points for bottles, cages, racks and guards, including mounts on the rigid forks.

See the full list here.

Frontier - Tried and Tested

The Frontier might be considered a Jack of all trades but the clever bit is, it's able to master most of them.
