Giant Reign Advanced 29 0 on test – long geometry with short travel suspension has us in for a surprise

It’s been hotly anticipated by fans: the Giant Reign 29! By the time Giant got on to the 29er bandwagon, it was already going along at full steam. So we were all the more excited to see how the bike would fare and if the new, bigger-wheeled Reign would do its legendary status justice.

**Giant** Reign Advanced 29 0 | 160/146 mm | 13.52 kg | € 8,499

The team behind Giant have redeveloped the new Reign 29 from the ground up. Nonetheless drawing on years of experience and proven technology, the frame is made of carbon fibre and features Giants proprietary Maestro linkage, offering 146 mm travel controlled by a FOX FLOAT X2 Factory shock. Up front, there’s a FOX 36 Factory GRIP2 providing 160 mm travel. Coming in at € 8,499, the Reign Advanced 29 0 has a race-ready spec which leaves little to be desired. The build includes only the best in componentry, such as SRAM CODE RSC brakes, X01 Eagle drivetrain and a RockShox Reverb dropper. However, we would have preferred a 32 t chainring instead of the 34 t it came with and the 150 mm dropper post isn’t quite long enough for a size L bike. The paint job of the frame is beautiful but not everything else has been given as much attention to detail. Prime examples are the ineffectively short chainstay protector and rubber plugs at the cable ports that keep on coming loose. However, the biggest flaw of the new Reign is the sizing. There’s a 38 mm leap in reach from size M to L, meaning that the bike is either too short or too long for a lot of riders. Most of our test riders are about 180 cm tall and fell between sizes – we eventually settled on the L with a reach of 493 mm.

**Easily damaged**
The paint quickly got chipped at the cable port for the shifter cable on the chainstay. Unfortunately, the chainstay protector is too short.

**Unchanged for years**
We don’t know how long Giant have been relying on the same rubber plugs for the cable inlets. What we do know is that they’ve never managed to stay there for very long.

**Extraordinarily fun**
The Maestro linkage of the Giant Reign 29 offers 146 mm travel and uses it very efficiently. It offers a lot of mid-stroke support, making for a poppy feel. Unfortunately, big hits following in quick succession soon bring it to its limits.

Specific Features

**Still too short**
To avoid being pulled too far forward on steep descents, we recommend raising the cockpit with spacers under the stem. By doing so, you will also shorten the effective reach by a few millimetres – which is welcome on the long bike.

**Pleasantly central**
The pedalling position on the Reign is spot on. Thanks to the steep seat tube angle and the firm rear suspension, it climbs excellently. We would have liked a longer dropper post on the descents.

Geometry and size of the Giant

Regarding the geometry of the Giant Reign 29, there’s one thing that struck us most: the extremely large jump in size from M to L. For many riders, size M is likely too short and L too long. We strongly recommended you take the bike for a test ride beforehand.

The Giant Reign Advanced 29 0 on the trail

Sitting aboard the Giant Reign 29 Advanced is a relaxing affair – in the most positive sense. The riding position is central and slightly stretched and the suspension doesn’t wallow, though it bobs slightly. On technical climbs, the Reign offers a lot of traction, whereas on forest service roads it might be worth reaching for the climb switch on the shock. The comparatively low 13.52 kg weight is noticeable when you push down on the pedals. The only thing hindering long days in the saddle is the 34 t chainring. Unless you’re very fit, we recommend installing a smaller version.

Long and direct – a combination for a very specific type of terrain. While the geometry performs best at speed, the suspension often reaches its limit when there.

The Reign 29 repeats the mantra that longer is better. Thanks to the long front triangle, the Giant instils you with confidence and feels very composed on fast and steep descents. However, at a certain point the hits become too big and the terrain too rough and the rear suspension reaches its limits. Here, it takes an experienced and powerful rider to keep the bike on course. Thanks to the suspension’s mid-stroke support, quick line changes are easy and it’s only when things get tight and slow that the bike is hindered by its length. The Reign feels most at home on fast, steep yet moderate trails. In this kind of terrain, the poppy suspension is a lot of fun.

Steep, fast trails without big hits – this is where the Reign feels most at home and is a lot of fun to ride.

How does the Giant Reign Advanced 29 0 compare?

The Giant Reign Advanced 29 0 is a bike with a unique character. Like the Trek Slash, the suspension feels very defined, which is combined with a very long front triangle similar to the Pole Stamina. If you find the Slash a touch nervous and the Stamina a bit too cumbersome, the Giant could be just the thing. For riders up to 175 cm, we recommend going for size M and riders from about 185 cm should stick to size L because of the unusually large gap between sizes – there’s not really a size for riders in between.

Tuning tip: more robust tires, depending on your riding style | smaller chainring for the climbs

Conclusion

The Giant Reign Advanced 29 0 is made for a very specific type of terrain and is not suitable for all types of riders. It instils you with confidence on steep and fast descents that aren’t too rough and is a very capable climber. However, it demands a lot of input on rough trails and tight sections.
