The Giant Reign is an extremely capable mountain bike, designed for enduro racing and tested at the very highest level. As well as being blisteringly quick over all types of terrain the Reign instils confidence when the going gets rough, is a capable climber and is fun to ride on challenging trails.

With 160mm of full suspension travel and dialled enduro geometry the Reign offers capable performance on technical trails. There are two frame options to choose from; the Giant Reign Advanced features an Advanced-Grade carbon composite main frame with an alloy rear end while you get a full ALUXX SL-Grade frame on the Giant Reign models. For 2017 you get the easy shifting of ‘one by’ drivetrains on all models.

Giant Reign Frame


Long and slack

Unlike most brands, Giant own the factory that makes both the aluminium alloy and carbon composite frames. This means that you get a very high quality frame at a very competitive price point.

With a slack 65 degree head angle and a generous reach, the Giant Reign offers confident performance on challenging terrain. Both the alloy framed Reign and the Advanced-Grade carbon composite Reign Advanced share the same dialled geometry with full internal cable routing and a tapered head tube for improved front end stiffness.

Lightweight and strong, the Advanced Grade carbon composite frames are built with high performance raw carbon fibres using a modified monocoque construction method which maintains strength while further reducing weight. While not quite as lightweight as carbon, the alloy frames are made from double butted 6011 aluminium using forming processes to offer an impressive strength to weight ratio for confident performance.

Giant Reign Suspension


Fully active rear suspension

Giant’s Maestro rear suspension system has been perfected on the Reign. The smooth action is combined with plenty of support to offer impressive levels of traction in the loose while still soaking up all the big hits on challenging trails. Maestro is a fully active design that keeps on working efficiently even while while pedalling and braking.

You get the capable performance of the RockShox Monarch RT shock on the Reign 2 while the Reign 1 and Reign Advanced 0 feature a Monarch Plus for improved consistency on long descents. The Reign Advanced 1 features Fox’s excellent Float X2 shock which offers impressive performance on every trail.

Up front you get a 160mm travel fork to match the rear. The Reign 2 features the capable RockShox Yari while the Reign 1 and Reign Advanced 0 feature the big hitting Lyric RC3. Staying with Fox suspension the Reign Advanced 1 features the high-performance Fox 36 fork.

The rear shock is mounted on bearings rather than bushings which offers smoother suspension performance.

‘One by’ drivetrains on every model

There’s absolutely no doubt that the Giant Reign has some hefty ambitions. With its wide bar, big discs, fat tyres and chain device it demands to be ridden hard - Dirt

For 2017 it is great to see that each of the Reign models now feature a ‘one by’ drivetrain, which offers a wide range of gears, with easy shifting and secure running on even the very roughest trails. Both Reign models feature SRAM 1x11 speed while the Reign Advanced 1 features Shimano XT 1x11 speed. Offering a massive 500% gear range, you get SRAM’s top flight XO1 Eagle 1x12 speed drivetrain on the Reign Advanced 0.

With 200mm/180mm disc rotors you get plenty of stopping power. Keeping the brands matched, stopping duties are taken care of with SRAM Guide disc brakes on the Reign 1 & 2 with Shimano XT on the Reign Advanced 1 and SRAM Guide Ultimate brakes on the Reign Advanced 0.

Giant Reign Wheels


27.5” on all models

Offering the ideal balance between rapid rolling and nimble handling the Reign rolls exclusively on 27.5” (650b) wheels. Giant have put a lot of effort into developing their wheel systems and you now find them on each Reign model. The top three bikes in the range feature carbon composite rims that offer improved stiffness with reduced weight, while the Reign 2 rolls on slightly heavier alloy rims.

In keeping with the Reign’s aggressive riding aspirations, the wheels are shod with wide Schwalbe tyres with the Magic Mary upfront offering superb levels of grip in all conditions, even on the most challenging terrain.

Tredz Opinion

A bike that can handle everything

The way the Reign handles the downhills is extremely confidence inspiring, it feels comfortable at high speeds and when it gets rough the Maestro suspension system soaks it all up! Charles Jones – Team Tredz enduro athlete

I've raced the Giant Reign on some of the top enduro tracks in the UK & Europe and it didn't disappoint. The long and slack frame makes it more of an aggressive bike so that you can ride confidently over any terrain, whether you are racing or just riding for fun.

If you want a bike that can handle everything, the Reign is the one for you. From your favourite blue run to the biggest descents in the world, the Giant Reign can do-it-all.
