Fast and agile, Cortex is a mid-travel full suspension trail bike frameset for big mountain epics on all terrain and flying round your local trail centre. It comes alive on long technical descents (we recommend a 140mm travel fork) big wheels and a stiff, responsive frame.

With bang up to date geometry, Cortex inspires confidence with a playful character. Stand up and mash on the pedals out of turns, manual sections of trail and pop off tree stumps, rocks and roots. Smash out short and loose technical climbs, flat-out descents and tight techy singletrack sections. The harder you push the bigger your grin.

Recommended - 140mm travel at the front and 135mm at the rear lets you carry higher speeds over rough ground without sacrificing pedalling efficiency.

Cortex' frameset is hand-welded from 6061 double-butted aluminium for the perfect mix of weight, rigidity and durability; with a slim hydroformed top-tube and down-tube designed to improve stiffness with just enough compliance to get you out of trouble. Internal cable and stealth dropper routing means clean lines, dampened with foam liners for a quiet ride. Dialed-in geometry and 2.4” tyre clearance gives heaps of grip; a comfortable and efficient climbing position for big days in the saddle; and a stable, spirited platform for smashing down descents.


Keeping up with industry standards, Cortex uses a UDH hanger. They're widely available so you can get rolling again sooner after any mid-ride mishaps!
