Trail tuned design: Balanced geometry with a 75-degree seattube angle puts the rider in a powerful pedalling position on climbs, while a slacker 66-degree head angle boosts confidence and control on technical descents.

Responsive handling: Lightweight ALUXX SL aluminium hardtail frame offers agile acceleration and maneuverability to help riders climb, corner and hammer the flats with efficiency and speed.

Smooth control: Giant Crest 34 suspension fork with 130mm of travel absorbs roots, rocks and ruts. Grippy, high-volume tyres boost traction on rugged terrain. And a dropper seatpost with handlebar remote lets you adjust saddle height on the fly for confident positioning on changing terrain.
