Giant and Liv have unveiled the new Revolt and Devote gravel bikes after prototype sightings at Unbound Gravel.

The bikes are officially named the Giant Revolt Advanced SL and Liv Devote Advanced SL. Both move away from the broader adventure focus of earlier models.

Giant and Liv now present each platform as a complete race system. The brands claim lower weight, improved stiffness, aerodynamic gains, and more aggressive gravel geometry.

The new bikes also increase maximum tyre clearance to 53mm. That gives riders more range for changing gravel surfaces and tougher race courses.

Revolt and Devote share a new carbon platform

The Revolt Advanced SL and Devote Advanced SL use the same core manufacturing approach. Giant Bicycle Group builds both with its high-modulus carbon resin system.

The shared process includes Carbon Nanotube Technology. Giant says this resin blend strengthens microscopic bonds between carbon layers and aims to improve impact resistance.

The bikes also use Continuous Fibre Technology. This applies long, unbroken carbon sheets to reduce overlaps and remove unnecessary material.

Precision Cold-Blade Cutting completes the process. Giant describes it as laser-precise mechanical cutting for cleaner carbon swatches and less wasted material.

In practical terms, Giant and Liv use a more advanced resin, longer carbon sections, and more precise layup preparation. The goal is lower frame weight without sacrificing race stiffness.

Giant says the new Revolt Advanced SL complete bike saves 288g versus the previous generation. The bare frame drops to a claimed 839g, saving 151g.

The fork weighs a claimed 385g. Giant says the frame and fork together save 176g compared with the outgoing chassis.

Liv uses the same layup process for the Devote Advanced SL. The brand pairs it with women-specific ergonomics and wind-tunnel development.

Liv says the Devote core race setup weighs a claimed 4,223g. That figure covers the frame, fork, wheels, and cockpit. It saves nearly 300g versus the previous model.

More aggressive geometry and claimed aero gains

Both platforms use integrated front ends and the Contact SLR XR handlebar on flagship builds. Giant lists that bar at a claimed 295g.

The geometry also shifts closer to a road-racing position. Both bikes feature lower stack, longer reach, steeper head tube angles, and reduced fork trail.

Giant claims the Revolt delivers an 18.99-watt advantage over the previous version. Liv claims the Devote delivers a 20.03-watt saving over its predecessor.

For the Revolt, Giant cites wind-tunnel testing that includes a 13.81W linear drag saving. It also lists 3.03W from rolling resistance, plus rotating-wheel savings.

The new Revolt Advanced SL has a 557mm stack height, down from 586mm. Reach increases to 395mm from 385mm.

The seat tube angle also steepens to 74.5 degrees from 73.5 degrees. Those figures compare with the previous generation.

Liv developed the Devote in the wind tunnel using Georgia, a 3D-printed adjustable mannequin. The mannequin matches professional Liv AlUla Jayco rider Georgia Baker.

Liv says this helped optimise the Devote AeroSystem shaping for real-world efficiency. The new Devote adopts a lower and longer position across nearly all sizes.

In a size medium, stack is 17mm lower than before. Reach is 8mm longer than the outgoing model.

Liv also specs longer stems across the range. The new bikes use 70mm to 90mm stems, compared with 50mm to 80mm previously.

One caveat matters for the aero comparison. Liv says the original Devote used a more upright, traditional all-road position in testing.

That means the full claimed wattage difference does not come from frame shaping alone. Position and setup also affect the measured result.

New Cadex wheels for top builds

The top Revolt and Devote Advanced SL models use the new Cadex Max GRX Wheelsystem. The wheelset has 50mm hookless carbon rims and carbon spokes.

Giant and Liv fit those wheels with Cadex GXR 45c tyres on the top builds. The Advanced SL models are the first bikes specified with the wheel-tyre combination.

Cadex says the wheelset weighs 1,320g with valves and tape. Without valves and tape, the claimed weight drops to 1,280g.

The complete system weight with tyres has not been stated. Cadex has instead highlighted drag and system-resistance figures.

Compared with the previous Cadex GX 40mm wheels, Cadex claims a 15.96W total aero drag reduction. That number includes linear and rotational drag.

Cadex also claims an 18.99W total system-resistance reduction versus the previous wheel setup.

The wheels can accept tyres up to 53mm. Cadex does not present that as the fastest setup, but it expands options for rougher gravel.

When purchased separately, the Cadex Max GRX Wheelsystem costs $4,000 or £3,499. The Cadex GXR tyre costs $85 or £65 each.

A sharper race identity

Giant and Liv frame the new Revolt and Devote as race bikes first. That marks a clear split from the adventure-led character of earlier models.

The brands also claim more stable front ends for fast fire roads and loose corners. The larger tyre clearance supports that race-course versatility.

Some improvement claims compare bikes that now differ substantially from their predecessors. The Advanced SL models share names with older versions, but the platforms are new.

The central story remains clear. Giant and Liv have rebuilt their flagship gravel bikes around speed, integration, weight reduction, and modern race positioning.
