Sonder Cortex

Fast and agile, Cortex is for epic days over mixed terrain. It comes alive on long technical descents. With 120mm travel, big wheels and a stiff responsive frame, making it great fun for the local trails, and also a hot contender for big down-country days.

With bang up to date geometry for 2024, 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 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.
