How it compares
180 mm at the fork almost exactly matches the 180 mm median of the 12 bikes in the “freeride bike” category in our database. The rear offers 170 mm, 10 mm less than the front. Among Nukeproof’s mountain bikes, the Nukeproof Giga Carbon is the model with the most fork travel. The frame is made of carbon.
According to Nukeproof, the Pro 290 T-GX build weighs 15.8 kg. Nukeproof uses RockShox suspension throughout.
Setup notes for this spec
- Fork (RockShox ZEB Select+): air goes in through the valve on top of the left leg. After every change, compress the fork firmly a few times before measuring SAG.
- 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.
- Shock (RockShox Vivid Select+ Air): get on the bike in your normal riding position, step off carefully and read the O-ring. Always cycle the shock a few times after pumping.
Target SAG for the Nukeproof Giga Carbon
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 Nukeproof specifies its own target SAG for your model, that takes priority.
180 mm fork, 60.0 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 31 mm | 24 % = 14.4 mm on the shock shaft |
| Trail | 20 % = 36 mm | 28 % = 16.8 mm on the shock shaft |
| Enduro / rough | 22 % = 40 mm | 30 % = 18.0 mm on the shock shaft |
| Bike park | 20 % = 36 mm | 27 % = 16.2 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.40″ 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: Schwalbe Magic Mary Evo 29x2.4 / Tacky Chan Evo 29x2.4.
| 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
You will find a suitable starting pressure on the sticker on the fork stanchion (or on the shock) or in the suspension manufacturers’ setup charts. Our calculator gives you a starting value including rebound for your weight and riding style. What matters afterwards is the measured SAG from the table above.
