29er trail mountain bike
Giant Stance
A modern aluminum trail bike with 130mm of FlexPoint rear suspension, a 140mm air fork, 29-inch wheels, 4-piston brakes and a size-specific dropper post—available in Matte Black and Almond.
More control for the next level of trail riding
The redesigned Stance pairs progressive 29er geometry with a stiffer, more integrated ALUXX aluminum chassis. Its 130mm FlexPoint rear suspension and 140mm Giant STL 34 fork are tuned for smooth traction, predictable support and confidence on technical terrain.
130mm FlexPoint suspension
The updated single-pivot system delivers active rear-wheel travel with reduced rear-triangle deformation and improved chassis stability under braking.
140mm Giant STL 34 fork
A dual-air spring and 34mm chassis provide sensitive small-bump response, mid-stroke support and controlled impact management.
Fox Rhythm rear shock
The 210×52.5mm shock is matched to the frame’s suspension curve for predictable traction and tunable rebound performance.
Shimano CUES 1×10
A 30T chainring and 11–48T cassette deliver simple shifting and practical range for steep trail climbs.
4-piston hydraulic brakes
Tektro HD-M5141 brakes with 180mm rotors provide strong, controlled braking on steep or loose terrain.
Size-specific dropper post
The Contact Switch AT dropper provides 110–200mm of travel depending on frame size, creating more room to move on descents.
A trail chassis built around stability and traction
Every major system is designed to give developing trail riders more confidence, easier setup and a cleaner, quieter bike.
ALUXX aluminum
Hydroformed, double-butted alloy tubing balances strength, stiffness and weight with Giant’s Smooth Weld construction.
29er trail geometry
A 65-degree head angle, higher stack and long wheelbase create stable, predictable handling on technical terrain.
Unified Suspension Setup
Fork and shock pressure recommendations are displayed on the bike to simplify initial suspension setup by rider weight.
Clean cockpit integration
Matched headset spacers and convertible internal or external cable routing create a tidy front end without sacrificing serviceability.
UDH-compatible frame
The 12×148mm rear end uses SRAM’s Universal Derailleur Hanger standard for easier replacement and drivetrain compatibility.
Tubeless-ready traction
Maxxis Dissector 29×2.4 tires and Giant AM30 rims arrive prepared for tubeless setup and support tires up to 2.5 inches.
