Details

Sail up steep climbs with smooth efficiency. Swoop down singletrack descents with speed and confidence. This aluminum hardtail delivers a balanced ride on XC terrain.

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
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. And a dropper seatpost with handlebar remote lets you adjust saddle height on the fly for confident positioning
