Giant 2025 XTC Advanced 29 1 Mountain Bike

Description

This Hardtail Goes Hard

The 2025 Giant XTC Advanced 29 1 Mountain Bike is made for responsive ride quality and maximum efficiency on fast, flowy singletrack. This lightweight composite hardtail is a great choice for XC racing or KOM chasing.

With its large-diameter 29-inch wheels and lightweight Advanced-grade composite frame, this responsive hardtail flies on XC terrain. The frameset is engineered for a 100mm fork, handcrafted with a specific composite layup schedule according to frame size. This creates an optimal stiffness-to-weight ratio with just the right amount of vertical compliance. It features wider Boost hub spacing, which improves wheel stiffness and adds clearance to run larger tires, plus a host of other features that let you dial in its performance on XC terrain.

Lightweight & Responsive

A handcrafted Advanced-grade composite frameset offers XC racers and riders a competitive advantage for climbing, accelerating and sprinting.

XC Efficiency

The frame is engineered with a high stiffness-to-weight-ratio, which translates to efficient pedaling power and precise handling on the trail.

Custom Compliance

Each frame is custom-tuned based on its size. Individual composite lay-up schedules are created to optimize vertical compliance to produce a smoother ride quality on XC terrain.
