Short-travel 29er full suspension mountain bike for epic days over mixed terrain


Fast and agile, Cortex is for epic days over mixed terrain. It comes alive on long technical descents with 120 mm travel, big wheels and a stiff responsive frame

With bang up to date geometry, Cortex is confidence inspiring 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 you grin.

Cortex frameset is hand-welded from 6061 double butted aluminium with a tapered ovalised top-tube and large section down-tube for a stiff chassis with just enough compliance to get you out of trouble. 66° head angle, 74.5° seat tube angle, 40 mm bottom bracket drop and a 465 mm reach (size large). Cortex’s dialed in geometry and 2.6” tyre clearance offers a comfortable and efficient climbing position for big miles and a stable, spirited platform for smashing up descents.
