How it compares
With 160 mm of fork travel, the Kona Process 153 is on the shorter side; the median of the 41 comparable bikes in the “enduro bike” category is 170 mm. The rear offers 153 mm, 7 mm less than the front. Within Kona’s mountain bikes, it sits between the Kona Process 134 and the Kona Process X on travel. The frame is available in aluminium or carbon.
Fork and shock come from RockShox on every build. In total, 3 different forks are used, from the RockShox Psylo Silver RC to the RockShox Lyrik Ultimate RC2 Charger 3 DebonAir+ w/ButterCups.
Setup notes for this spec
- Air fork (RockShox Psylo Silver 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.
- Shock (RockShox Deluxe Select+): 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 Kona Process 153
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 Kona specifies its own target SAG for your model, that takes priority.
160 mm fork, 57.0 mm shock stroke (Process 153, CR)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 27 mm | 24 % = 13.7 mm on the shock shaft |
| Trail | 20 % = 32 mm | 28 % = 16.0 mm on the shock shaft |
| Enduro / rough | 22 % = 35 mm | 30 % = 17.1 mm on the shock shaft |
| Bike park | 20 % = 32 mm | 27 % = 15.4 mm on the shock shaft |
160 mm fork (CR/DL)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 27 mm |
| Trail | 20 % = 32 mm |
| Enduro / rough | 22 % = 35 mm |
| Bike park | 20 % = 32 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
Basis: 2.50″ 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. Stock tyres: Maxxis Assegai 29x2.5" WT EXO+ / TR / 3C MaxxGrip / Maxxis DHR II 29x2.4" WT EXO+ / TR / 3C (27.5x2.4" WT size S); Maxxis Assegai 29x2.5" WT EXO Dual Compound / Maxxis DHR II 29x2.4" WT EXO Dual Compound (27.5x2.4" size S); Maxxis Assegai EXO+ TR 3C 29x2.5" WT / Maxxis Minion DHR II EXO+ TR 3C 29x2.4" WT (27.5x2.4" WT size S).
| 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.
