How it compares
With 160 mm at the fork, the Mondraker Sly sits above average: across the 101 bikes in the “e-MTB for trail and touring” category in our database, the median is 150 mm. The rear offers 150 mm, 10 mm less than the front. Within Mondraker’s e-mountain bikes, it sits between the Mondraker Prime and the Mondraker Dune on travel. Mondraker builds the frame from aluminium.
At €5,999 for the SLy R build, pricing is typical for the category (median €5,500). For the SLy RR build, Mondraker asks €6,999. For suspension, Mondraker combines components from FOX and RockShox. In total, 2 different forks are used, from the RockShox Lyrik Base to the Fox 36 29 Float Performance GRIP. It is powered by Bosch Performance Line SX with a 400 Wh battery.
Setup notes for this spec
- Air fork (RockShox Lyrik Base): 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: 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 (RockShox Deluxe Select+): 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 Mondraker Sly
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 Mondraker specifies its own target SAG for your model, that takes priority.
160 mm fork, 55.0 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 27 mm | 24 % = 13.2 mm on the shock shaft |
| Trail | 20 % = 32 mm | 28 % = 15.4 mm on the shock shaft |
| Enduro / rough | 22 % = 35 mm | 30 % = 16.5 mm on the shock shaft |
| Bike park | 20 % = 32 mm | 27 % = 14.9 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.60″ 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.
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.40 bar (20 psi) | 1.60 bar (23 psi) |
| 70 kg | 1.52 bar (22 psi) | 1.72 bar (25 psi) |
| 80 kg | 1.64 bar (24 psi) | 1.84 bar (27 psi) |
| 90 kg | 1.76 bar (26 psi) | 1.96 bar (28 psi) |
| 100 kg | 1.88 bar (27 psi) | 2.08 bar (30 psi) |
| 110 kg | 2.00 bar (29 psi) | 2.20 bar (32 psi) |
| 120 kg | 2.12 bar (31 psi) | 2.32 bar (34 psi) |
Air pressure in the fork and shock
You will find a guide value for air pressure on the fork sticker (or on the shock) or in the suspension makers’ charts. Our calculator also takes riding style and rebound into account. In the end, measured SAG is what counts.
