Giant Revolt X Review: Suspension at Both Ends on a Gravel Bike

Introduction

The Giant Revolt X is a new addition to the brand’s long-running Revolt family of gravel and adventure bikes, and it changes the formula in a meaningful way. Rather than a fully rigid setup, the Revolt X runs suspension at both ends. Up front sits a RockShox Rudy suspension fork, and at the rear the bike uses a dropper post that also provides a small amount of suspension travel.

To accommodate that fork, Giant redesigned the frame, which is offered in either carbon or aluminium. The head tube is much shorter than on a standard Revolt, and the geometry settles at a 71 degree head tube angle and a 73 degree seat tube angle. The bottom bracket has been lowered compared with the regular Revolt and the chainstays are shorter, while the rear dropout keeps the flip chips from the standard bike so the wheelbase and handling can be adjusted.

The result is a bike built for riders who like to blur the line between gravel and mountain biking. This article covers the frame changes, the specification on the top build, and how the Revolt X behaves on rooty woodland trails.

Who the Giant Revolt X Is For

The Revolt X is aimed at riders who spend as much time on rough, loose and rooty trails as they do on smoother gravel and road surfaces. If you enjoy pushing a gravel bike onto terrain where a mountain bike would normally be the safer pick, the suspension fork, the suspension dropper post and the 45 mm tyres with a chunky tread pattern all work in your favour.

It also makes sense for riders who want a single bike that copes with a wide range of surfaces instead of maintaining several machines. The trade-off is weight and added complexity, so riders who mostly ride fast, smooth gravel may still find the standard Revolt the lighter and simpler choice.

Main Strengths

The most interesting component on the Revolt X is the seat post. It offers between 75 mm and 100 mm of drop from a handlebar-mounted lever, and on top of that it provides roughly 25 mm of suspension action. That combination is unusual, because most dropper posts compromise comfort by replacing a compliant carbon post with a solid, unforgiving one. Riders who want maximum comfort can swap it for a regular round 30.9 mm post or for Giant’s own D-Fuse D-shaped post.

Giant also fits shorter stems and wider bars than on the regular Revolt, which adds control and composure on descents. The wheels are the brand’s own lightweight and very wide carbon fibre rims, and the tyres measure 45 mm across with an aggressive tread, a notable departure from the slick rubber found on the standard Revolt.

The drivetrain on the Pro model pairs a SRAM Rival 1x setup with an Eagle GX rear derailleur and a 10-52 cassette. Combined with the suspension and the dropper post, that wide range gives the bike a coherent identity: low gears for the steep climbs that come with technical trails, and suspension to keep the wheels planted on the way back down.

Tyre clearance is generous, and the flip chips in the rear dropout let owners shorten or lengthen the wheelbase to tune how the bike handles. The frame itself is a genuinely fresh design rather than a bolt-on adaptation, and it is offered in both carbon and aluminium so the platform spans a wider range of budgets.

Things to Consider Before Buying

The Pro model tested weighs around 10 kg in a size ML without pedals, which looks heavy on paper for a gravel bike at this price. In practice, the extra mass is far less noticeable than the figure suggests, but riders who prioritize low weight above all else should weigh that carefully.

The seat post also produced a clunking noise on an early ride, apparently as it topped out and hit its stops. It may simply be a new component bedding in, but it is worth checking on a test ride and monitoring over the first few months of ownership.

Suspension is not for everyone. Giant continues to sell the standard Revolt, and for many riders that remains the smarter, lighter and simpler purchase. The Revolt X asks for more money and more maintenance in exchange for capability on rougher ground.

Pricing starts at £3,000 in the UK, with four builds in the range. The Pro model covered here retails at £5,500 in the UK and $6,200 in the US, so it sits firmly in the upper end of the gravel market.

Ride Impressions on Mixed Terrain

On a short first ride through woodland, the suspension fork and suspension seat post smoothed out the bumps from tree roots that were largely hidden under fallen leaves. The effect is a gravel bike that rides noticeably smoother than a rigid setup, and smoother than a regular Revolt, which is exactly the point of the X badge.

Despite the 10 kg build weight, the bike does not feel heavy once it is moving. It accelerates willingly and carries speed in a way that suggests the carbon wheels and chunky tyres are doing a lot of the work. The 10-52 cassette makes steep, loose climbs genuinely manageable, and the low gearing pairs naturally with the suspension, since the trails that justify a fork usually demand the easiest gears for the return trip.

The wider bar and shorter stem add confidence when the trail points downhill and the surface turns loose. Riders who like to explore a mix of road, smooth gravel and deeper woodland trails will find the Revolt X gives them a wider margin before the terrain starts to feel like too much for the bike.

Buying Advice

If your local trails are rooty, steep or loose, the Revolt X makes a convincing case for itself. It covers road, smooth gravel and technical woodland in a way that few single bikes manage, and it does so without losing the efficiency that makes a gravel bike enjoyable on the way to the trailhead.

If your riding is mostly smooth gravel and tarmac, the standard Revolt is the better value and the easier bike to live with. Suspension adds weight, service intervals and cost, and it only earns its place when the terrain genuinely calls for it.

What to Check Before You Buy

Giant offers the Revolt X in four builds, starting at £3,000 in the UK. The Pro model, with its SRAM Rival 1x drivetrain, Eagle GX rear derailleur and 10-52 cassette, retails at £5,500 in the UK and $6,200 in the US. Confirm the build that suits your budget before committing, since the suspension platform is shared but the components and weight vary across the range.

Sizing deserves attention as well, given the shorter head tube, wider bars and shorter stem compared with the standard Revolt. Sit on the bike if you can, and check the dropper post action and the top-out behaviour at the same time. If you prefer a rigid setup, remember that the suspension post can be replaced with a round 30.9 mm post or a D-Fuse post for a more traditional feel.

Conclusion

The Giant Revolt X is a clear step forward for riders who want one bike that handles road, gravel and technical woodland without feeling out of its depth. Suspension at both ends, wide-range gearing, chunky 45 mm tyres and a redesigned frame add up to a package that is comfortable, confident and genuinely versatile.

It is not the lightest option, and the seat post clunk is something to keep an eye on. But for riders who like riding the line between gravel and mountain biking, the Revolt X delivers the extra bandwidth that makes difficult trails fun rather than intimidating.
