Giant's latest generation Revolt gravel bike broke cover last month when local legends Brendan 'Trekky' Johnston and Cole Patton tackled Unbound Gravel on a prototype version of the bike.
This same bike recently won a sack of potatoes and a green and gold jersey at Devil's Cardigan, which doubled as the Gravl National Champs a few weekends ago, with Trekky playing very well. According to Giant, Trekky was involved in the development and testing of this new bike.

First introduced in 2015, the new Revolt still borrows some design cues from its predecessors. However, it has evolved into a full-on gravel racer, with the more aggressive Revolt X coming in as an adventure machine.
We recently received the fourth generation Revolt Advanced Pro 0 at Flow's Queensland HQ. Let's get into the new.
Overview of 2025 Giant Revolt
The Giant Revolt is a gravel racing bike, which fits in the same category as the Cervelo Aspero, Canyon Grail, and Scott Addict Gravel.
For 2025, the Revolt received an update with a new carbon frame and fork. The silhouette of the frame is the same with its dropped seatstays and sloping top tube, as well as a compression-fit bottom bracket.
The new bike is certainly one that we can read as a revolution rather than a revolution. The geometry is unchanged, the only differences are the chainstays, which are 5mm shorter, and the wheelbase. The previous generation Revolt rode very well as a gravel racer, so it's no surprise that Giant opted for a 'don't-fix-it-if-it-is-broken' mentality.
Our medium size Advance Pro 0 tips the FlowScalesOfTruth™ at 8.23kg without pedals or bottle cages.
Everything is inside – for better or for worse
Where comes the big difference in frame furniture. From the front, Giant has chosen to use cables with a high-end earphone bearing. While the Taiwanese brand is looking for an aerodynamic advantage – which independent tests show to be real – and there is less interference in the models with electronic changes, but in the mechanical models, changing that headset bearing or cables and housing will be a big job.
It's not all doom and gloom, as Giant has added integrated downtube storage. A tool-free hatch sits below the front bottle cage holders, and Giant includes a tool pouch to keep everything organized.
Despite its stature as a race bike, Giant has also brought a host of mounts and holders throughout the frame, including three-pack bolts on both fork legs and provisions for full fenders. Other gravel bikes in this category, such as the new Cervelo Aspero and the Specialized Crux, eschew additional mounts for weight and convenience.
Adjustable geometry is back
Giant carried a flip chip in the rear to allow for 5mm chainstay adjustment. This will allow riders to slightly alter the steering characteristics and stability of the bike depending on the environment and riding position.
Increasing the length of the chainstay means you can fit a bigger wheel between the stays. In the long case, Giant says the new Revolt can handle rubber up to 53mm wide, and the frame has 42mm of wheel space on the short side. Our test bike had a set of Cadex GX 40mm tires.
The flip chip also means that the Revolt is not compatible with UDH. SRAM's new Red XPLR Transmission is one of the best-kept secrets, and even F1 driver Valtteri Bottas was riding in Unbound Gravel this year, so it's an interesting decision from the Taiwanese brand.
While rumors of a HALO team collection are few and far between, we can guess that the rear hanger-free mech design will soon make its way down the product line.
Will the geometry adjustment on the new bike be enough of a draw to outweigh the future proofing and ability to walk into any bike shop and find a replacement if you have to have a whoopsie? Only time will tell.
ID-Fuse front and rear
Giant chose to use its Revolt finishing kit, each part based on the D-Fuse product design language. The heart of this system is based around a D-shaped tube designed to promote flexibility in one plane to maximize comfort without sacrificing performance.
At the rear, the Revolt sees a D-Fuse seat that is said to allow up to 12mm of front and aft flex. Giant pioneered these square seats back in 2014 and since then they have been widely adopted by many brands. However, like the previous generation of this bike, it will also accept a 30.9mm round post, including droppers thanks to the included shim.
The D-Fuse concept has also been used on the handles. Giant says it has increased the “push” down compliance for a smoother ride quality while also increasing the “pull” stiffness up, aiming to increase precision and control compared to its round Contact bars.
2025 Giant Revolt models and price
While there are both alloy and carbon models of the Revolt, only the carbon version received frame updates. The steel bike only gets a new paint job next year.
Giant Australia has advised that it will deliver five models of the Revolt, with prices ranging from $3,199 AUD up to $8,499 AUD for the Advanced Pro 0 we have for testing.
