How it compares
Up front the Kellys Thorx runs 150 mm – 10 mm more than the 140 mm median we calculated from 44 bikes in the “trail bike” category. The rear offers 140 mm, 10 mm less than the front. Within Kellys’s mountain bikes, it sits between the Kellys Gibon and the Kellys Swag on travel. Kellys builds the frame from aluminium.
At a minimum of 15.0 kg (50 29 (RockShox Yari RC) build), the Kellys Thorx is heavier than its category median of 13.9 kg – 1.1 kg more. There are 0.8 kg between the lightest and the heaviest build. Kellys uses RockShox suspension throughout. The fork line-up ranges from the RockShox 35 Gold RL to the RockShox Yari RC.
Setup notes for this spec
- Air fork (RockShox 35 Gold RL): 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+ RT): 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 Kellys Thorx
SAG is the share of travel your weight already uses in the riding position. The table gives it straight in millimetres – read the O-ring on the stanchion and on the shock shaft and adjust the air pressure until it matches. Any figures from Kellys take priority.
150 mm fork, 55.0 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 26 mm | 24 % = 13.2 mm on the shock shaft |
| Trail | 20 % = 30 mm | 28 % = 15.4 mm on the shock shaft |
| Enduro / rough | 22 % = 33 mm | 30 % = 16.5 mm on the shock shaft |
| Bike park | 20 % = 30 mm | 27 % = 14.9 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
The values apply to 2.35″ 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 Hans Dampf Evo Super Trail 60-622 (29"x2.35) Tubeless Easy, ADDIX Soft, folding / SCHWALBE Nobby Nic Evo Super Trail 60-622 (29"x2.35) Tubeless Easy, ADDIX SpeedGrip, folding; SCHWALBE Hans Dampf Evo Super Trail 60-622 (29x2.35) Tubeless Easy, ADDIX Soft, folding, front / SCHWALBE Nobby Nic Evo Super Terrain 60-622 (29x2.35) Tubeless Easy, ADDIX SpeedGrip, folding, rear.
| Ready-to-ride weight | Front | Rear |

| 70 kg | 1.55 bar (22 psi) | 1.75 bar (25 psi) |
| 80 kg | 1.67 bar (24 psi) | 1.87 bar (27 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.
