How it compares
170–180 mm at the fork almost exactly matches the 170 mm median of the 41 bikes in the “enduro bike” category in our database. Within Giant’s mountain bikes, it sits between the Giant Stance and the Giant Glory on travel. Depending on the build, the frame is aluminium or carbon.
At 15.4 kg (Advanced build), the weight is close to the category median of 15.7 kg. Entry costs €3,700 for the Reign build – less than the category median of €4,750. The top build, Advanced, costs €7,000. Fork and shock come from RockShox on every build. The fork line-up ranges from the RockShox ZEB Delta RC to the RockShox ZEB Ultimate Charger 3.2 RC.
Setup notes for this spec
- Air fork (RockShox ZEB Delta RC): the air valve is on top of the left leg under a cap. Change pressure in small steps (about 5 psi (0.34 bar)) and cycle the fork a few times afterwards so the air chambers can equalise.
- Rebound: on RockShox suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- Air shock (RockShox Super Deluxe R): measure SAG in your riding position, ideally with a helper holding the bike. Cycle the shock a few times after every pressure change.
Target SAG for the Giant Reign
The table converts the recommended SAG percentages into millimetres, so you can check them with the O-ring directly on the stanchion and on the shock shaft. Adjust the air pressure until the value is right. If Giant specifies its own target SAG for your model, that takes priority.
170 mm fork, 62.5 mm shock stroke (Reign, Advanced)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 29 mm | 24 % = 15.0 mm on the shock shaft |
| Trail | 20 % = 34 mm | 28 % = 17.5 mm on the shock shaft |
| Enduro / rough | 22 % = 37 mm | 30 % = 18.8 mm on the shock shaft |
| Bike park | 20 % = 34 mm | 27 % = 16.9 mm on the shock shaft |
180 mm fork, 65.0 mm shock stroke (SE)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 31 mm | 24 % = 15.6 mm on the shock shaft |
| Trail | 20 % = 36 mm | 28 % = 18.2 mm on the shock shaft |
| Enduro / rough | 22 % = 40 mm | 30 % = 19.5 mm on the shock shaft |
| Bike park | 20 % = 36 mm | 27 % = 17.6 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.50″ wide tyres, tubeless with a trail casing. With an inner tube about 0.2 bar (2.9 psi) more, with an insert about 0.1 bar (1.5 psi) less. Stock tyres: Maxxis Assegai 29x2.5 / Minion DHR II 27.5x2.4.
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.43 bar (21 psi) | 1.63 bar (24 psi) |
| 70 kg | 1.55 bar (22 psi) | 1.75 bar (25 psi) |
| 80 kg | 1.67 bar (24 psi) | 1.87 bar (27 psi) |
| 90 kg | 1.79 bar (26 psi) | 1.99 bar (29 psi) |
| 100 kg | 1.91 bar (28 psi) | 2.11 bar (31 psi) |
| 110 kg | 2.03 bar (29 psi) | 2.23 bar (32 psi) |
| 120 kg | 2.15 bar (31 psi) | 2.35 bar (34 psi) |
Air pressure in the fork and shock
The sticker on the fork (or on the shock) and the manufacturers’ setup charts give you a first pressure. Our calculator is more precise and suggests rebound too – always check the result via SAG.
