Focus THRON²: suspension setup & specs
The Focus THRON² is an e-MTB for trail and touring with 150 mm of fork travel and 140 mm at the rear. It is powered by Bosch Performance Line CX, 85 NM, 120 NM update via Flow App. This page lists the 3 current builds with fork, shock and shock size and gives matching starting values for SAG and tyre pressure.

How it compares
150 mm at the fork almost exactly matches the 150 mm median of the 101 bikes in the “e-MTB for trail and touring” category in our database. The fork has 10 mm more travel than the rear end with 140 mm – a common layout that takes load off the front on steep terrain. On travel, it slots in between the Focus VAM² SL and the Focus JAM² in the Focus range. Focus builds the frame from aluminium.
Focus quotes 25.4 kg for the 8 build; that is 2.0 kg more than the 23.4 kg median of 49 comparable bikes. There are 1.1 kg between the lightest and the heaviest build. Entry costs €3,699 for the 7 build – less than the category median of €5,500. For the 9 build, Focus asks €5,699. Depending on the build, fork and shock come from FOX, RockShox and SR Suntour. In total, 3 different forks are used, from the SR SUNTOUR XCR 36 X Boost to the FOX 36 AWL HD Sport. It is powered by Bosch Performance Line CX, 85 NM, 120 NM update via Flow App with a 800 Wh battery.
Setup notes for this spec
- Fork (RockShox Psylo Silver RC): 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.
- Air shock (SR SUNTOUR Edge-X R): measure SAG in your riding position, ideally with a helper holding the bike. Cycle the shock a few times after every pressure change.
- e-MTB: because of the extra weight, start with slightly more tyre pressure – the surcharge is already built into the table below.
Target SAG for the Focus THRON²
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 Focus specifies its own target SAG for your model, that takes priority.
150 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 26 mm |
| Trail | 20 % = 30 mm |
| Enduro / rough | 22 % = 33 mm |
| Bike park | 20 % = 30 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.50″ wide tyres, tubeless with a trail casing, including the e-MTB surcharge. 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: Maxxis Minion DHF, EXO, 29 x 2.5" | Maxxis Minion DHF, EXO, 29 x 2.5".

| 120 kg | 2.20 bar (32 psi) | 2.40 bar (35 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.
