    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. With 120mm travel and big wheels, Cortex is for mountain trails and down-country epics.

    Geometry and Sizing

    Sizing

    It is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height.

    Generally we recommend:
    Small: Riders between 5ft 2in and 5ft 7in (157-170cm)
    Medium: Riders between 5ft 6in and 5ft 10in (167-177cm)
    Large: Riders between 5ft 9in and 6ft 2in (175-187cm)
    X-Large: Riders of 6ft 2in + (187cm)
