Fast and agile, Cortex is a trail riding, down-country, all terrain mountain bike for seriously epic days out. It comes alive on long technical descents with 120 mm rear 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.
I find NX Eagle to be the sweet spot between performance and price. You're getting a lot of the benefits of GX Eagle mixed with some of the value of SX. It's a real Goldilocks groupset.
Then, chuck in the excellent Pike forks, which give you great control over the rough stuff, and our lightweight, performance Alpha 29" wheels, that spin up quick and roll smoothly, and you've got a build that'll ride beautifully.
