Crank up steep climbs with smooth efficiency. Swoop down singletrack descents with speed and confidence. This hardtail 29er delivers a balanced ride on XC terrain.

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 aluminium hardtail frame offers agile acceleration and manoeuvrability 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.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
