The Giant Reign is a classic in the enduro segment. It was a mainstay of Enduro racing’s formative years. However, things have been quiet around the bike and it’s become quite dated. That’s all about to change with the new Giant Reign 29 – we’ve put it to the test.

The flagship model: the Giant Reign Advanced Pro 0 | Travel: 160/156 mm | wheel size: 29″| Price: € 8,500 | Weight 13.10 kg (size medium)

Less is more, or why 146 mm travel is enough

Giant isn’t a brand that follows every trend and it often takes the truly gigantic bike manufacturer some time to implement changes, but when Giant do something, they do it right. Which is exactly what they did with the Reign 29. As the name suggests, the bike rolls on big 29″ wheels and it comes with 160 mm travel up front and 146 mm at the rear. It may not sound like much at first, but to Giant, the quality of the travel is more important than the length. The goal was to create a bike that responds sensitively yet offers enough reserves for hard hits, all without wallowing its travel and making the bike feel cumbersome.

Giant are continuing with their proprietary Maestro linkage on the new Reign 29, offering 146 mm travel.

The Maestro linkage on the new Reign has been further refined, reducing the leverage ratio to 16% progression (0-100% travel). This achieves a more constant rebound rate and thus offers more traction.

The new Giant Reign 29 in detail

Giant have invested a lot of time in refining the lines of the new bike. It now looks a lot better. Interesting fact: many of the new accents and colours were inspired by the women’s brand, LIV.
A highlight of the new Reign 29 Advanced Pro 0 is its Chameleon paint job, which shimmers different colours depending on the light.

Of course, Giant haven’t only revised the rear linkage and gone for larger wheels, the frame itself has also been updated. The main pivot point has been moved further forward, allowing you to insert the seat post deeper into the seat tube. This means that the Reign is now compatible with longer dropper posts. Speaking of compatibility, the new Reign 29 also has enough room in the front triangle to accommodate a water bottle and the carbon fibre models are FOX Live Valve ready.

The front triangle will happily accommodate a large water bottle

Giant rely on a carbon fibre rocker link and Trunnion Mount shock across the range (including the aluminium models). Unfortunately, Giant haven’t changed the cable routing and still use the same rubber plugs, which often detached themselves from the frame in the past. The chainstay protector also seems like a bit of a half-hearted effort compared to the elaborately crafted versions seen on the bikes of many of their competitors.

Something’s missing. The chainstay protector is rather short. Although we didn’t encounter any problems with the large 34T chainring on our test bike, you’ll risk damaging the paintwork if you decide to fit a smaller chainring.
We would have preferred a BSA BB in place of the press-fit version. However, according to Giant, the latter requires significantly more space, which wasn’t available due to the Maestro linkage.
Giant have long been using the same rubber plugs for their cable inlets – and they’ve long been a source of frustration. Too bad that Giant are still using them on the Reign 29.

All the latest trends combined – the geometry of the new Reign

Longer, slacker, lower – these are the latest trends in the geometry of Enduro bikes. The Reign also ticks all of these boxes. For example, the 65° head angle is slack, the 493 mm reach in size L is long, and the bottom bracket with a drop of 30 mm is pleasantly low for quick direction changes. Giant also rely on short offset forks with either 42 mm (RockShox) or 44 mm (FOX). The stack height is rather low compared to the length of the bike. The 439 mm chainstays are neither very long nor exaggeratedly short.

Three carbon, two aluminium and one very special Reign model

Giant is offering the new Reign 29 in three carbon versions called the Reign Advanced Pro, as well as two aluminium Reign 29 1 and Reign 29 2 models. As in the past, there will also be a Reign SX model featuring a 170 mm travel fork and a coil shock. The Reign 29 SX is based on the same aluminium ALUXX SL frame.

A bike for those who like it rough: the new 2020 Giant Reign SX
The Giant Reign SX comes with 170mm travel up front …
… combined with a coil shock at the rear.
Giant have their right priorities right, speccing a high-quality Grip2 fork…
…saving on the rear derailleur instead – relying on SRAM’s NX Eagle.

Pricing for the new Reign 29 starts at a fair € 2,900 for the Reign 2 followed by the Reign SX for € 3,799. The most affordable Reign Advanced Pro will set you back by € 4,300. For the flagship Reign Advanced Pro 0, you’ll have to pay € 8,500.

The Reign Advanced Pro 0 features FOX Factory suspension with Grip2 damping on the 36 fork.
Giant also spec their lightweight TRX carbon wheelset, which is available aftermarket with DT 240 hubs for around € 2,000.
200 mm brake rotors on the front and rear ensure maximum braking power.
Unfortunately, Giant don’t take full advantage of the new seat tube/rocker mount design and opt for a 150 mm dropper post on the L and XL bikes – we would have wanted a 175 mm model.
Race-ready: the chain guide, bash guard and a 34T chainring will delight racers. Less fit riders will have to downgrade to a 32T or 30T model.

All models come with a 12-speed SRAM Eagle drivetrain and high-quality MAXXIS tires. Unfortunately, only the flagship model is specced with the more robust EXO+ variant – even the SX has to make do with the EXO casing. Despite the improvement in the design of the seat tube/rocker mount, GIANT continue to fit rather short dropper posts. The S comes with a 100 mm dropper, the M with 125 mm and the L and XL with 150 mm. The models specced with RockShox suspension don’t get piggy-back shocks either. In our eyes, the bike offering the best value for money is the Reign 1 with a FOX 36 Performance Elite Grip2 fork and X2 shock, SRAM GX Eagle drivetrain and CODE R brakes. The flagship Advanced Pro 0 leaves nothing to be desired, built up with carbon wheels and complete FOX factory suspension. You also get the Chameleon paint job that shimmers different colours depending on the light.

The Giant Reign 29 Advanced Pro 0 on the trail

To test the Giant Reign 29 Advanced, we travelled to Revelstoke in Canada. There we were able to put the Reign 29’s climbing capabilities to the test on a technical uphill trail as well as some relaxed forest service roads on the first day. The riding position is pleasantly central, and the seat angle sufficiently steep so that you never feel like you’re pedalling from too far behind, even with the shock open and the saddle not pushed all the way forward. On even terrain such as forest roads, you can feel the rear suspension bobbing slightly, but it never wallows. It can be worth reaching for the climb switch in those situations, depending on personal preference. On technical climbs, the Reign offers a lot of traction and willingly climbs uphill. Thanks to the low weight of just 13.10 kg (manufacturers specs), the bike is pleasantly fleet-footed – but it’s still an enduro bike, of course. In tight sections, it takes some effort to get the front wheel around the corners. Due to the low bottom bracket in combination with the 170 mm cranks, you also have to be careful with the timing of your pedal strokes or risk snagging them on roots or rocks as we did several times.

Despite its length and travel, the Giant Reign 29 climbs very efficiently – at least with the high-end spec.

When the trail points downhill, you immediately notice how much room you’ve got to move around on the bike. You feel super integrated between the big wheels, which instils you with a lot of confidence from the get-go. Let go of the brakes and the bike quickly picks up speed with the rear end sensitively absorbing irregularities on the trail. We have to praise the FOX Factory suspension at this point for its super sensitive and very defined performance. The fork and rear suspension harmonise well despite the difference in travel, always providing plenty of traction. Although it’s long, the bike doesn’t feel sluggish. The rear end provides a lot of pop and mid-stroke support which makes it easy to get the bike airborne or spontaneously change direction. Quickly switch to the high-line before you hit that turn? No problem!

Thanks to the long front triangle, the bike instils you with confidence

The weight distribution between the wheels is somewhat back-heavy, which means that you have to shift your body weight forward to generate enough grip on the front wheel in flat sections and tight corners. However, if the terrain is steep enough and you’re going fast, the bike’s handling is very intuitive and extremely composed. Active riders will be able to ride the bike very directly but also get loose. The bike invites you to flick it into corners.

You have to keep your weight on the front wheel for it not to wash out in the corners.
From alpine adventures to the next Enduro race – the Reign 29 can do it all. Provided the terrain is sufficiently challenging, or the bike will quickly get bored.

On steep and rough trails, the bike feels composed and instils the rider with confidence. Just let the brakes go and hold on. We would only have wanted a longer travel dropper post to get the saddle even further out the way. Due to the short head tube, we would also advise adding a few more spacers under the stem, which in turn reduces the reach by a few millimetres. The componentry proved to be reliable in our test and was perfectly suitable for the application. The carbon wheels were neither too stiff nor uncomfortable. We didn’t encounter any issues during the two days that we tested.


The Giant Reign 29 convinced us on demanding trails with its enormous composure and stability. Thanks to its active suspension, it doesn’t feel slow or cumbersome either. This is a bike that will put a smile on the faces of experienced racers as well as weekend warriors that typically ride rough and demanding trails. it climbs efficiently too. We would only have wanted a little more attention to detail on the frame.


  • very stable, composed handling
  • excellently balanced suspension
  • hard to beat on steep terrain
  • good value for money
  • good climbing characteristics


  • boring on flat trails
  • technical climbs require physical effort and good crank timing
  • a lot of room for improvement with regards to cable routing and chainstay protection
