How it compares
With 200 mm at the fork, the Rocky Mountain Slayer sits above average: across the 12 bikes in the “freeride bike” category in our database, the median is 180 mm. The rear offers 180 mm, 20 mm less than the front. Among Rocky Mountain’s mountain bikes, the Rocky Mountain Slayer is the model with the most fork travel.
Fork and shock come from RockShox on every build. The fork line-up ranges from the RockShox Boxxer Select Charger 3.2 RC to the RockShox Boxxer BASE Charger 3 RC. With the RockShox Vivid Coil HBO, the Park build has a coil shock – here the spring rate determines SAG.
Setup notes for this spec
- Fork (RockShox Boxxer Select Charger 3.2 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 RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- Coil spring (RockShox Vivid Coil HBO): if SAG is off, only a different spring rate will fix it. Preload should just keep the spring from rattling; more preload makes the shock less supple.
Target SAG for the Rocky Mountain Slayer
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 Rocky Mountain take priority.
200 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 34 mm |
| Trail | 20 % = 40 mm |
| Enduro / rough | 22 % = 44 mm |
| Bike park | 20 % = 40 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
The values apply to 2.50″ 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: F: Maxxis Assegai 2.5 3C MaxxGrip DH Tubeless Ready | R: Maxxis Minion DHR II 2.5 MaxxTerra DH Wire Bead; F: Maxxis Minion DHF 2.5 WT 3C MaxxGrip DH Tubeless Ready | R: Maxxis Minion DHR II 2.4 ST DH Wire Bead.

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.
