Updated: 25th January 2018
With an updated frame for 2018, the Giant Reign cements its place as the pure-bred race bike that everyone loves messing about on. 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.
We review the two alloy framed Reign models alongside the two Reign Advanced models with a carbon frame. With 160mm of full suspension travel and dialled enduro geometry, the Giant Reign is an extremely capable mountain bike designed for enduro racing and tested at the very highest level.
The fact that the new Reign frame looks very similar to the previous version is testament to the fact that the Giant are well ahead of the curve when it comes to enduro bike design. The 2018 frame sees refinements that build on the already great design of this hugely popular enduro bike. The 65-degree head angle remains the same, but the top tube length has been increased by 15mm across all sizes for more accurate sizing. A new forged carbon rocker link increases stiffness while the trunnion mount allows for a longer stroke shock - more about that later.
The Reign Advanced models get an Advanced Grade carbon composite mainframe. Built using a modified monocoque construction method, with high performance raw carbon fibres, this frame is strong, stiff and lightweight. While not quite as lightweight as carbon, the Aluxx-SL grade alloy framed bikes are made from double butted 6011 aluminium using forming processes to offer an impressive strength to weight ratio for confident performance when the going gets tough. Both the alloy framed Reign and the carbon composite Reign Advanced share an Aluxx-SL rear triangle. All bikes feature the same dialled geometry.
Giant have refined the Reign for 2018 and although the shape looks similar, there are subtle tweaks to continue to wring greater performance out of this class act. - Dirt
The rear shock is mounted on bearings rather than bushings which offers smoother suspension performance.
Giant’s excellent Maestro rear suspension system has been further improved on the 2018 Reign. The trunnion shock mount has allowed Giant to spec a longer stroke shock which gives more consistent performance, especially on those long descents. The shock tunes have been tweaked too, so the bike tends to sit higher in its travel. This improves the climbing position as well as making more efficient use of the 160mm travel on the descents. Maestro is a fully active suspension design that keeps on working efficiently even while pedalling and braking. Fork travel is the same as the rear wheel travel for a balanced ride.
The alloy framed Reign 1 & 2 both feature RockShox suspension front and rear with the Reign 1 getting a higher spec Lyric Fork and Super Deluxe rear shock. Fox supply the suspension on the Reign Advanced 1 with a 36 Performance Elite fork and Float DPX shock. At the top of the range the Reign Advanced 0 gets a RockShox Lyric RCT3 fork with a Super Deluxe coil shock. The Reign 1 and the Reign Advanced 1 both get a new remote lever that allows you to firm the shock up for more efficient climbing.
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
Each Reign and Reign Advanced bike features a ‘one by’ drivetrain, which offers a wide range of gears, with easy shifting and secure running on even the very roughest trails. The Reign 2 is the only bike with a Shimano drivetrain with its 10-speed cassette offering a wide gear range. All the other models get a SRAM Eagle 12-speed drivetrain that offers a massive 500% gear range, so you’ll have more than enough gears for every trail on the mountain.
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 and Reign Advanced 1 & 0 with Shimano Deore on the Reign 2. Wide bars, short stems and dropper posts are ideal for aggressive trail and enduro riding, you will find them fitted as standard on all models.
The Giant Reign rolls exclusively on 27.5” (650b) wheels which offer the ideal balance between rapid rolling and nimble handling. You get tough wheelsets on all models. The Reign one gets Giant’s own P-AM2 wheelset while all the other models get high quality DT Swiss Enduro wheels. The Reign 1 and Reign Advanced 1 both feature DT Swiss E1700 wheels while the Reign Advanced 0 get the same wheelset that has had sop much success in the EWS, the DT Swiss EX 1501 Spline. All the DT Swiss wheels feature wide 30mm rims that offer great support for the tyres. All the wheels are tubeless ready.
It is great to see high-quality Maxxis tyres on all Reign models. With a Shorty up front and a High Roller II on the rear the Reign is perfectly set up to ride those loose, loamy trails that UK enduro riders live so much.
The DT Swiss wheels have an Enduro World Series pedigree that will inspire confidence, especially on the very roughest trails.
Ideal for enduro racing the Giant Reign is also a great mountain bike for aggressive trail riding. From challenging trail centre loops to bike park uplifts the Reign offers a confident, fun ride when the going gets tough. Lightweight and efficient enough for all-day-long rides the Reign really comes alive when the trails get gnarly.
