With a lightweight frame, 130mm suspension fork, and 27.5" wheels with high-volume tires, this hardtail offers loads of traction, speed, and fun on the trail.

Key Performance Factors:

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

- Responsive handling
The lightweight ALUXX SL aluminum 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 tires boost traction on rugged terrain. A dropper seatpost with a handlebar remote lets you adjust saddle height on the fly for confident positioning on changing terrain.
