Details
GET YOUR DAILY DOSE OF SINGLETRACK. 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 seattube 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 on changing terrain.
