Bikes

Amp up your trail-riding adventures with this all-conquering 29er. Whether you’re gunning for faster enduro times or bagging a big backcountry loop, do it like a boss on this big-wheeled singletrack shredder. It took years for our team of engineers, product designers and pro riders to create a new short-travel 29er that met their high standards. The wait was worth it. The latest iteration of this legendary trail bike marks a huge step forward, offering a true advantage in all-round trail performance. It starts with a full composite frame that’s fitted with our most up-to-date Maestro suspension. The Advanced Forged composite rocker arm and trunnion-mount shock help produce 115mm of smooth rear-wheel travel that’s active and sensitive to small bumps, giving you killer traction and confident control. And the frame geometry is updated with progressive headtube and seattube angles, shorter chainstays and a longer toptube—all engineered to balance the speed and control of its 29-inch wheels with the quickness and agility you need to rail corners, hammer through rock gardens and do it all with confidence and control. 29er confidence and control Larger 29-inch diameter wheels roll over rough terrain with balance and stability, giving you the momentum to tackle technical climbs and the confidence to fly on fast, rugged singletrack descents. Latest suspension tech Updated Maestro rear suspension features a trunnion-mount shock with a longer stroke and smoother feel. With 115mm of full rear-wheel travel (and 130mm up front), it has the new Advanced Forged Composite upper rocker arm for increased stiffness and strength plus lower overall frame weight. Trail-tuned chassis The lightweight Advanced-grade composite frameset features updated geometry, including an aggressive 66.5-degree headtube angle and 74.5-degree seattube angle, plus a 44mm fork offset. The result is agile and efficient climbing capabilities plus added control for high-speed descents.

Proven through countless pro wins, this lightweight composite cyclocross bike delivers quick acceleration, smooth handling and total control on dry pavement, loose dirt, deep sand or slick mud—everything you need to aim for the podium. ELITE LEVEL EFFICIENCY - Advanced-grade composite frameset is 17.5 percent lighter than the previous generation while retaining its best-in-class torsional/pedaling stiffness.

Go fast, get rowdy, nail new lines with total control. We took everything you love about the legendary Reign and re-imagined it for 29-inch wheels. It’s progressive, it’s confident, and it’s born to fly on aggressive enduro style terrain. When it comes to building the ultimate enduro machine, we look to Giant Factory Off-Road Team riders who are out there pushing the limits of their bodies and bikes. This bike is for them—and for everyone else who loves to charge hard. We engineered the geometry of the Advanced composite frame and swingarm around larger diameter 29-inch wheels. That means shorter chainstays, a longer toptube, and just the right angles with the headtube (65 degrees) and seattube (76.8 degrees). Then we gave it an updated Maestro suspension system with 146mm of rear suspension. Aided by a new trunnion-mount shock and Advanced Forged Composite rocker arm, we came up with a system that feels super plush, active and shreddable. Beyond that, the new Reign Advanced Pro 29 features everything you need in a pro-level enduro machine, including a cleanly routed dropper seatpost, the latest Giant WheelSystem with Boost hub spacing, and tubeless tires set up right out of the box. Race-bred suspension Maestro rear suspension developed and tested under extreme conditions of Enduro World Series races. A trunnion mount shock has a longer stroke and smoother feel, and the Advanced Forged Composite upper rocker arm adds stiffness while lowering overall frame weight. The trunnion mount also allows longer dropper posts. Progressive enduro geometry The Advanced-grade composite frameset features updated enduro-style geometry, so you can ride aggressive descents and rail corners with confidence. The 65/76.8-degree headtube/seattube angles with a 42/44mm fork offset produce confident front-end handling with high-speed stability and control. 29er confidence and control Larger 29-inch diameter wheels roll over rugged enduro terrain with improved balance and stability, giving you the momentum to crank up tough climbs and the confidence to fly on fast, technical descents.

If speed is your obsession, this is your bike. You train, you put in the work, and this aero machine does the rest. Built to give you an edge when it really counts—on the attack, in the sprint, going all out—it delivers energy-saving efficiency and race-winning aero performance. Developed and proven by the fastest sprinters on the CCC Team WorldTour squad, the Propel Advanced SL Disc delivers ultimate speed through integrated aerodynamics. It’s engineered with Giant’s AeroSystem Shaping technology, which means every tube shape and angle is optimized for minimal drag. These tubes feature a “truncated ellipse” shape, which also result in a frame that is ultra-stiff and superlight. Disc-brake technology is integrated into the frameset with flat-mount calipers and thru-axles for optimal wheel stiffness and braking performance. For pro-level road performance and the ultimate aero advantage, the new Propel Advanced SL Disc puts you way ahead of the pack. Integrated aerodynamics AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR Aero cockpit produce the best overall aero performance. Total control Integrated disc brakes deliver powerful stopping power and modulation for added control in variable weather. Thru-axles boost stiffness and improve overall handling and an integrated WheelSystem with a 65mm rear rim and 42mm front rim optimizes aerodynamics and control. Unrivaled efficiency Advanced SL-grade composite frameset features Giant’s highest performance materials and manufacturing processes for optimized stiffness and the lowest weight in its category.

Don’t get us wrong, we’re all for racing. Grand Tour top steps, Classic’s Monuments—they’re in our DNA. But sometimes riding simply to ride, riding for the love of riding, is just what we need. And this is what the Aethos lives for. Sure, it’s given nothing up to performance, and happens to be the lightest frame out there, but with no compromise to style. Aethos: Billions of calculations in the pursuit of one thing—the perfect ride. Top off the world’s lightest frame with SRAM’s 12-speed RED eTAP AXS groupset and Roval’s featherweight Alpinist wheels and you’re left with a perfectly balanced top-tier ride that gives up nothing in the name of performance. The Aethos frame has been designed with the perfect combination of ultimate ride feel, light weight, and style—from accelerating up steep pitches and descending technical descents, to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. But how, you ask? By reinventing the traditional road shape found on bikes of the past, we’ve subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process that we’ve perfected over multiple decades and you have the lightest frame out there (585 grams, S-Works, size 56cm). The Aethos is more than just a new bike, it’s the first of a new breed. A featherweight frame is useless without confidence-inspiring ride characteristics, which is why we’ve developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, we were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and you’ll realize this sublime ride sets a new standard. Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind. We’ve also spec’d it with Roval’s all-new Alpinist carbon seatpost and wheels, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride.
