How it compares
Up front the Yeti SB140 runs 160 mm – 20 mm more than the 140 mm median we calculated from 44 bikes in the “trail bike” category. The rear offers 140 mm, 20 mm less than the front. Within Yeti’s mountain bikes, it sits between the Yeti SB135 and the Yeti LT on travel. The frame is made of carbon.
At a minimum of 14.5 kg (C2 90 build), the Yeti SB140 is heavier than its category median of 13.9 kg – 0.6 kg more. With a starting price of €6,700 (C2 90), the Yeti SB140 is above the category median (€3,000). Yeti uses FOX suspension throughout.
Setup notes for this spec
- Air fork (FOX Performance 36): 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.
- Air shock (FOX Performance Float X): measure SAG in your riding position, ideally with a helper holding the bike. Cycle the shock a few times after every pressure change.
Target SAG for the Yeti SB140
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.
160 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 27 mm |
| Trail | 20 % = 32 mm |
| Enduro / rough | 22 % = 35 mm |
| Bike park | 20 % = 32 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
Basis: 2.50″ tyre width, tubeless, trail casing. If you run tubes, add about 0.2 bar (2.9 psi); with an insert, about 0.1 bar (1.5 psi) less is enough. Stock tyres: Maxxis Minion DHF 2.5 EXO / Maxxis Minion DHR II 2.4 EXO.
| 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.
