How it compares
On travel, the Nukeproof Hyperfly is right where the “cross-country full-suspension bike” category usually is: 120 mm up front against a median of 120 mm from 23 bikes. On travel, it slots in between the Nukeproof Tracker and the Nukeproof Mega Carbon in the Nukeproof range. Nukeproof builds the frame from carbon.
Every build uses a FOX fork.
Setup notes for this spec
- Fork (FOX 34 Float Factory Grip): 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 FOX suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- Hardtail: only the fork needs setting up. With no rear suspension, rear tyre pressure is the key adjustment for comfort and grip.
Target SAG for the Nukeproof Hyperfly
Instead of percentages, this table gives SAG directly in millimetres, measurable with the O-ring on the stanchion. Change the pressure step by step until you reach the value; if Nukeproof gives its own target SAG, use that.
120 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 20 mm |
| Trail | 20 % = 24 mm |
| Enduro / rough | 22 % = 26 mm |
| Bike park | 20 % = 24 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
The values apply to 2.40″ wide tubeless tyres with a trail casing. With an inner tube add about 0.2 bar (2.9 psi), with an insert take off about 0.1 bar (1.5 psi). Stock tyres: Schwalbe Rick Evo XC Pro 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
You will find a guide value for air pressure on the fork sticker or in the suspension makers’ charts. Our calculator also takes riding style and rebound into account. In the end, measured SAG is what counts.
