How it compares
On travel, the Radon Jealous is right where the “cross-country hardtail” category usually is: 100 mm up front against a median of 100 mm from 46 bikes. Of Radon’s mountain bikes, the Radon Jealous offers the least travel up front. Radon builds the frame from carbon.
The Radon Jealous does well on weight: 9.2 kg for the 9.0 build is 0.8 kg below the median of comparable bikes (10.0 kg). Within the range, weight varies by 0.6 kg. With a starting price of €2,999 (8.0), the Radon Jealous is above the category median (€1,450). The top build, 9.0, costs €3,799. In total, 2 different forks are used, from the RockShox SID SL Ultimate 2P to the Fox 32 Float Factory.
Setup notes for this spec
- Fork (RockShox SID SL Ultimate 2P): 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: turn the red FOX and RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- 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 Radon Jealous
The table converts the recommended SAG percentages into millimetres, so you can check them with the O-ring directly on the stanchion. Adjust the air pressure until the value is right. If Radon specifies its own target SAG for your model, that takes priority.
100 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 17 mm |
| Trail | 20 % = 20 mm |
| Enduro / rough | 22 % = 22 mm |
| Bike park | 20 % = 20 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
Basis: 2.40″ tyre width, tubeless, trail casing. If you run tubes, add about 0.2 bar (2.9 psi); with an insert, about 0.1 bar (1.5 psi) less is enough.
| 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 suitable starting pressure on the sticker on the fork stanchion 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.
