Refined trail geometry with a slacker head tube and higher stack creates a stable, confident ride position. The new Contact Switch AT dropper post and long-post compatibility (up to 200mm) gives you room to move on descents. A wide-range 1X drivetrain, powerful 4-piston brakes, and tubeless tires deliver simple shifting, precise speed control and planted traction—so you don’t just ride the trail, you master it.
Re-engineered FlexPoint rear suspension with a Crest FloTrac TR shock delivers active, consistent performance through 130mm of travel. The single-pivot system boasts the lowest rear-triangle deformation in its class, while new kinematics with tailored shock spring curve deliver a more linear wheel path. The result is a smooth, predictable feel with unbeatable traction and mid-stroke support. Up front, the dual-air Giant STL 34 suspension fork smooths out rocks and roots. And our Unified Suspension Setup makes it easy to dial-in the settings.
A new hydroformed ALUXX aluminum chassis is engineered for strength, stiffness, and low weight. Seamless shock integration enhances frame stiffness and delivers amore connected ride feel. A smooth cockpit-to-frame transition with integrated spacers keeps the front end clean, while flush cable guides help ensure quiet performance. Convertible internal/external routing adds adaptability. The result is a sleek, precise, trail-ready frame that rides as sharp as it looks
State-of-the-art aluminum material delivers best-in-class strength-to-weight ratio. The frameset also features double-butted tubing, FluidForm shaping, and innovative welding technologies including Smooth Weld to give it a high-performance ride quality.
Single-pivot suspension system with 130mm of smooth, active rear travel for greater control on technical trails. Updated design results in less rear triangle deformation and higher anti-rise performance for greater chassis stability and balanced geometry under braking force.
A fully tunable rear shock that’s engineered to complement FlexPoint suspension kinematics. Featuring Triple Flow Path technology, it delivers a wide range of adjustability on spring and damping for predictable traction control without any pre-set limitations.
Designed for trail riding, the STL 34 uses a Twin Air spring system to deliver a sensitive, controlled, and highly tunable feel across a wide range of terrain. From early stroke compliance to supported end-stroke control, it tracks the ground and manages impacts for a smoother, more confident ride.
Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/2” lower and 1 1/2” upper) and tapered steerer tube (1 1/2” lower and 1 1/8” upper) work in conjunction to provide optimal steering stiffness.
An oversized bottom bracket area features a threaded, 73mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and increased stability on the non-driveside.
Designed for confident trail riding, a slacker head angle (now 65 degrees) and higher stack height (now 615mm) delivers greater control and more confident handling on technical terrain.
Contact Switch AT dropper post lets you quickly lower your saddle for descents and technical sections. The frame is designed to allow longer posts (200mm for L and XL sizes), so you have more room to move and greater control.
Optimal air pressure and damper setting recommendations, based on rider weight, are predetermined and presented in easy-to-read graphic displays on the bike itself—one on the rear shock and one on the fork—and also online.
Custom headset spacers and top cap designed to match the head tube shape for a clean outlook and seamless connection between the frameset and the handlebar/stem. The head tube and headset offer convertible cable routing that allows for internal or external routing.
Cable guides are designed to be flush with the frame, creating a streamlined look, quiet performance, and easy servicing. The frame also features integrated protection on the chainstay and underneath the down tube.
This Performance level frame material features 6061 alloy with single-butted tubes to produce strong, lightweight framesets for a variety of different bikes and riding styles.
A proven “single-pivot” design that uses the flexing action of the chainstay/seatstay junction to produce a lightweight and durable suspension system with 4.7 inches/120mm of rear travel.
Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
