“Good things made even better” is the motto for the new Giant Reign Advanced 0. The old Giant Reign was very popular with racers thanks to its potent geometry. For the coming season Giant has made the main frame even longer and reworked the rear triangle. Has this made the bike even faster?

Giant Reign Advanced 0
Giant Reign Advanced 0 | 160/160 mm (front/rear) | 13.56 kg | € 6,999

The new Giant Reign Advanced 0 comes with top-of-the-line components as standard! At the rear of the carbon frame is a RockShox Super Deluxe Coil shock, which is mounted to a new carbon trunnion-mount linkage. For long uphills or fast sprints, the shock can be stiffened directly from the handlebar. At the front, Giant relies on a RockShox Lyrik RCT3 suspension fork with 160 mm of travel. Providing grip is a MAXXIS Shorty 2.5″ WT on the front and a High Roller II at the back. Both tires come mounted tubeless as standard – nice! Giant’s own dropper post performs reliably, but the remote lever seems outdated. Due to the low stack height (593 mm in size L), all testers installed two large spacers under the 40 mm stem.

Even with a coil shock and an aluminium rear triangle, Giant have kept the Reign Advanced 0’s weight down to 13.56 kg (without pedals). In combination with the effective suspension adjustment on the handlebars, the bike is surprisingly efficient. If you ride predominantly long and steep climbs, it is advisable to push the saddle as far forward as possible in order to compensate for the slack seat tube angle (73°). On downhills, the greatest strength of the new Reign is its enormous stability. The rear suspension generates huge amounts of traction and stays glued to the ground. Paired with a 65° head angle and a reach of 473 mm (size L), the bike rides through rock gardens as if on rails.

High speeds are its greatest strength! You get onto the bike, take a good grip on the handlebar, and then let go of the brakes. Let’s go! On long stages, the rear end of the Reign saves a lot of energy. Long, open turns at high speed are no problem with this bike. If the trail is tight and twisty, however, you will have to manhandle it. At slow speeds the Reign feels slightly undefined and sluggish. If you want to be fast on flat sections, you will have to pedal hard and try to make yourself light. When pumping, it feels as if a lot of power is absorbed by the plush rear suspension.

Bump-absorption Happy
The RockShox Super Deluxe Coil damper sucks up more than an American V8, helping the bike achieve a tremendous amount of traction.

Not so nice
The remotes of the dropper post and the RockShox shock didn’t convince us in terms of ergonomics.

On the edge
Despite its tall knobs, the MAXXIS Shorty has a very wide range of applications. They don’t fold on hard surfaces, but handling is less defined than a Minion DHF or DHR. On soft ground, on the other hand, the Shorty is amazing!

Jacked up
Due to the low stack height (593 mm in size L), all the testers installed several spacers under the stem in order to improve control over the bike, especially on steep terrain.

The classic has gotten even better! The Giant Reign convinces with its plush and stable character – which unfortunately has made it a bit vague.


The Giant Reign shows its strengths mainly on long, hard, and fast descents. If you want to plow through a trail at Mach 5, this is your bike. If you are looking for an agile, playful bike, you will need to look elsewhere.


– very stable and composed
– components are race-ready
– plush suspension


– rather cumbersome, imprecise handling
