Last year, when we spoke to Brendan Trekky Johnston about racing the Lifetime Grand Prix, he mentioned that he and teammate Cole Patton had been working with Giant on a racier version of the Revolt gravel bike. Now the Taiwanese manufacturer has revealed a brand-new Giant Revolt Advanced SL and a Liv Devote Advanced SL, both built from the ground up for gravel racing.
We first saw a sneak peek at this year’s Unbound Gravel, where Trekky rode this new version of the Revolt to a career-best fourth-place finish, battling 321.86km/200mi of apocalyptic rain and mud along the way.
Now Giant and Liv have shared the details of this new platform, spruiking a lighter chassis, aero gains, a more aggressive geometry and a UDH. There’s also new gravel wheels, tyres and cockpits too. Lets dive in!

An overview of the Giant Revolt Advanced SL and Liv Devote SL
Sitting atop the Taiwanese brand’s range of gravel bikes, the Revolt Advanced SL and Devote Advanced SL are made using Giant’s highest-grade Advanced SL carbon fibre. Giant spins its own carbon weaves in-house and, among other things, says it uses cold-blade cutting technology to make ultra-precise cuts and prevent fibre deformation caused by excess heat during laser cutting. According to Giant, this results in fewer swatches throughout the frame, allowing for more uninterrupted fibres and reduced weight.
Last time we visited Giant’s Taiwanese manufacturing facility ahead of the launch of the latest Anthem XC bike, we actually got to see some of the process live!
Giant claims the new frames and forks are both lighter than their predecessors, with the Revolt Advanced SL frame coming in at 839g and the fork at 385g, while the Devote Advanced SL is 830g and the fork is 385g — a reduction of 161g and 160g, respectively.
Beyond the weight loss, Giant also claims that a byproduct of all this is increased stiffness in both power transfer and handling efficiency.
This new bike has been optimised around a 45mm tyre; however, the brand says there is room for a 53mm / 2.0in tyre.
It’s worth noting that this bike does not replace the Revolt and will sit alongside it in Giant’s gravel range.
Integration and aerodynamics
Marginal gains are the colour of the season in gravel racing, and the new flagship gravel bikes from Giant and Liv both feature the brand’s one-piece Contact SLR XR bar and stem combo, complete with hidden cables. Giant claims this saves a few watts of aerodynamic drag and is quite a departure from the comfort-focused D-Fuse cockpit on the normal Revolt.
This Contact SLR XR bar/stem combo will be available as an aftermarket option for $799 AUD.
While there is an argument for integration like this in the wind tunnel, it does make changing the bar width or stem length an expensive exercise. With the cables fully hidden, travelling or servicing the top headset bearing also becomes a headache.
The total aero revamp has brought airflow-smoothing shapes to the tubes across the frame, most noticeable in the fork. You also won’t find luggage-carrying provisions or rack mounts on this bike, nor the downtube storage found on the regular Revolt and Devote. That said, there are mounts for a top-tube bag and an accessory mount just ahead of the seat cluster, on the inside of the front triangle.
Giant conducted separate wind tunnel tests on the two bikes and even went so far as to create an aero-testing dummy modelled on Georgia Baker from Liv AlUla Jayco to use for the Devote.
Giant/Liv based this testing around a metric they are calling ‘total system resistance’, which takes into account aerodynamic drag and rolling resistance. According to the brand, the new Revolt Advanced SL showed a total system resistance reduction of 18.99 watts, while the Devote Advanced SL with ‘Georgia’ on board saved 20.03 watts, compared to the non-Advanced SL version of the bike.
Giant Revolt Advanced SL Geometry
With its roots as a do-everything gravel bike, the Revolt (no SL) had a relatively upright geometry that could be made aggressive with a negative rise stem.
Giant says the new bike is designed around pitching the rider’s weight forward to create an efficient and aerodynamic body position.
Available in six sizes from XS to XL, the new Revolt in size medium maintains the same 71.5° head angle, while the seat angle is a full degree steeper at 74.5°. With the rear flip chip gone, Giant has settled on 433mm chainstays, closer to the 435mm long position of its predecessor.
While the implications for the geometry are important, getting rid of the flip chip also means this new Revolt (and the Devote) can now accommodate a UDH and SRAM’s full-mount derailleurs.
The reach has grown by 8mm to 395mm, while the stack has been chopped off at the knees, dropping 29mm to 556mm.
Liv Devote Advanced SL Geometry
The new Devote offers a slight variation in geometry, with the most drastic differences being a 10mm shorter standover height and a 5mm shorter seat tube. There are also minor differences in the top tube length, reach and wheelbase; however, they are within ~2mm.
Liv is also only offering the Devote in four sizes, from XS to XL.
Revolt and Devote Advanced SL models and pricing
Giant Australia is bringing in three models of the Revolt Advanced SL and Devote Advanced SL. Both carry essentially the same spec, barring the 140mm rear rotor and narrower bars on the Devote.
We’ll also get a frameset option of the Giant version.
The top-end Advanced SL 0 model with full SRAM Red XPLR and CADEX’s fresh new wheels (which retail for $5,399 AUD alone!) is priced at $13,999 AUD. The range starts at $8,999 AUD for the Advanced SL 2 model. You still get a SRAM Rival XPLR groupset and Giant’s new CXR 0 carbon wheels (more on these and the new CADEX hoops below) for that price. Giant says the Revolt models will be fully available at launch, with limited stock of the Liv Devote Advanced SL 0 and 2 available. The Devote Advanced SL 1 will land shortly after.

CADEX Max GXR and CRX 0 Wheels
Giant and CADEX are also launching two new carbon gravel wheels, the CADEX Max GXR and Giant CXR 0, and some fresh GXR tyres too!
CADEX Max GXR
Key specs
- Claimed weight | 1,320g
- Depth | 50mm
- Internal width | 25mm
- Price | $5,399 AUD
At 50mm deep and a claimed 1,320g with tape and valves, these wheels use what CADEX calls its Max hub-and-spoke technology. This is based on a one-piece hub, flange, spoke, and rim structure that forms a fully integrated system. Giant claims this minimises drag and smooths airflow.
CADEX’s Super Aero Carbon Spokes are paired with its R3-C60 Aero Hub, which features a 60T ratchet and the Ratchet Wave spring system. This aims to ensure consistent pressure on the ratchet for smoother operation and rolling efficiency. If previous Giant/CADEX wheels are anything to go by, these suckers will be LOUD!
Sticking with the spokes for a moment, they aren’t bonded to the rim and can be adjusted with hidden internal titanium nipples. Though they are bonded to the hub, so don’t break one!
Many of the latest gravel wheels are seeing the internal width balloon beyond 30mm — Zipp’s 303 XPLR are 32mm internal, while the latest ENVE G-SES are 35mm. These new CADEX wheels are 25mm between the beads, which is the de facto baseline. This means that when paired with a ~45mm tyre, the casing profile should be well supported and nicely rounded.
The bead itself is hookless and sees what CADEX calls Wire Guard, where the bead wall is reinforced and measures 5mm across to spread the load over a wider area during a rim strike. In theory, this should create a stronger rim and reduce the chance of a pinch flat.
You’ll find these Gucci hoops stock on the Revolt Advanced SL 0 and Devote Advanced SL 0, but the CADEX Max GXR are also available aftermarket, priced at $5,399 AUD! Ouch!

Giant CXR 0
Key specs
- Claimed weight | 1,435g
- Depth | 50mm
- Internal width | 25mm
- Price | $3,099 AUD
The CXR 0 is a slightly more budget-friendly version of the Max wheels above, which you’ll find spec’d on the Advanced SL 1 and 2 models.
With a full carbon rim, complete with the hookless WireGuard bead and bladed carbon spokes, they see the Giant Low Friction Aero hub. This also means the spokes aren’t bonded to anything and can be replaced if there is a problem.
Claiming a weight of 1,435g, including tape and valves, you still get the 60T ratchet and Giant’s Wave Spring System.
These too are available aftermarket and priced at a much easier-to-swallow $3,099 AUD. Giant Australia has not confirmed that these wheelsets will land locally.
CADEX GXR tyre
Key specs
- Sizes | 700 x 45, 700 x 50
- Claimed weight | 409g (40mm), 530g (50mm)
- Price | $110 AUD
The last piece of this substantial launch from Giant is the new GRX tyre. Based on a 170TPI casing, it features the brand’s Race Shield+ puncture protection under the tread and an X-Shield reinforced sidewall construction.
Available in 40mm and 50mm widths and claimed to weigh 490g and 530g respectively, the tread sees a highly packed centre strip with a 2x2x3 block structure, each having a vertical sipe.
There is an alternating transition tread with ample space to clear mud and a shoulder tread that ramps up as it moves out towards the edge of the casing for maximum purchase when the bike is on edge.
According to Giant, these will retail for $110 AUD and will be available aftermarket, though availability is to be confirmed.
Flow’s take
Giant has always made bikes to suit the masses, and no model exemplifies this better than the Revolt, which is still in the brand’s range. Gravel is evolving and changing, and there is a growing segment that is focused on racing and marginal gains.
With riders like Trekky, Cole Patton and Melisa Rollins at the pointy end of the LifeTime Grand Prix, there was an obvious need for something aggressive and high-performance from Giant. That’s not to say you can’t race on the regular Revolt, but it was a generalist and a bloody good one at that. But when you’re ingesting 120g of carbs an hour and wearing aero socks to try and extract every ounce of performance from your equipment, a generalist might not be the right tool for the job.
This is not going to be a bike for everyone, but we’re happy to see Giant not falling behind in this respect and bringing an aggressive gravel bike with room for fat tyres and swapping the flip chip for a UDH. We’re hoping to get one in for review soon. Stay tuned for more.
