How it compares
On travel, the Yeti SB165 is right where the “enduro bike” category usually is: 170 mm up front against a median of 170 mm from 41 bikes. The fork has 5 mm more travel than the rear end with 165 mm – a common layout that takes load off the front on steep terrain. Among Yeti’s mountain bikes, the Yeti SB165 is the model with the most fork travel. Yeti builds the frame from carbon.
At 15.7 kg (T3 X0 AXS Transmission build), the weight is close to the category median of 15.7 kg. Within the range, weight varies by 0.3 kg. With a starting price of €6,900 (C2 90 Transmission), the Yeti SB165 is above the category median (€4,750). For the T3 X0 AXS Transmission build, Yeti asks €10,600. Yeti uses FOX suspension throughout. In total, 2 different forks are used, from the FOX Performance 38 to the FOX Factory 38 Grip X2. With the FOX Factory DHX2 2 Pos Lever, the C2 90 Transmission build has a coil shock – here the spring rate determines SAG.
Setup notes for this spec
- Air fork (FOX Performance 38): 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 FOX suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- Coil spring (FOX Factory DHX2 2 Pos Lever): 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 Yeti SB165
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 Yeti specifies its own target SAG for your model, that takes priority.
170 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 29 mm |
| Trail | 20 % = 34 mm |
| Enduro / rough | 22 % = 37 mm |
| Bike park | 20 % = 34 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: Schwalbe Magic Mary Trail Pro 2.5 Radial Ultra Soft / Schwalbe Albert Gravity Pro 2.5 Radial Soft.
| 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
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.
