Multi-activity 29er for fast, flowy trails, hurtling over cross-country and loading up with bags for days of deep backcountry riding


Set it up for XC race speed and a trail centre slayer or set it up for all-day comfort loaded with bags and ride rugged country, bothy trips to Cape Wrath and beyond.

Hardtail trail centre mountain bike compatible with 27.5+ or 29 inch wheels. Its beauty is in its simplicity, but don’t confuse simple with basic. Clean lines, internal routing make Frontier an exceptional bike.

Frontier is our versatile alloy all-rounder - ride it hard around the trail centre, load it up and sneak off for a midweek bikepacking trip through mid-Wales, pocket your passport and continue much further afield.

The geometry is relaxed for long day comfort but it’s no slouch. The 6061 aluminium frame provides a durable, low maintenance and stiff chassis giving a responsive kick as you demand power when the slope steepens or enjoy feedback and precision through the corners.

Frontier can be tailored to ride how you want it to ride. The geometry and head angle allows capacity to take a 100mm fork or ride fully rigid. So you can have it set up for XC race speed or all-day comfort and put in the miles. Big 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.

Optimised for 1x drivetrains, Frontier is available in SX Eagle builds with rigid or 100mm suspension forks.

Frontier excels both loaded and unloaded, absorbing every surface you ride - you decide how you want to pack for your adventure. With a triple bottle cage mount for versatility and multiple boss mounts on the fork Frontier is an adaptable off-road explorer. Fast and stable for trail centre or big mountain days and responsive when loaded up in the modern lightweight bikepacking style of travel.

Wherever you are in the world - squeezing in an after work loop or halfway through an adventure of a lifetime; Frontier eats up long-distance trails with style and comfort with the shameless enthusiasm of a trail centre hardtail.
