SB140 C2 Eagle 90 Factory Mountain Bike

What Our Gearhead® Experts Are Saying:

"The SB140 C2 Factory runs C/Series carbon with Performance Switch Infinity V2 suspension, a Fox Performance 36 fork, and a Fox Factory Float X rear shock. The 160mm front and 140mm rear travel split is tuned for aggressive trail and all-mountain terrain, and the Eagle 90 drivetrain covers the full gradient range with a 10-52 cassette."

Who It's For

Trail riders who want Switch Infinity V2 and a Factory rear shock on a C/Series carbon platform.

The SB140 C2 Factory targets riders with solid trail experience who are ready for a longer-travel bike capable of handling technical all-mountain terrain.

What It's For

Technical trail riding where 160mm of travel is an asset.

The SB140's 160mm front and 140mm rear travel with a relatively linear leverage curve delivers great small-bump sensitivity, a supportive mid-stroke, and a composed feel at the end of the travel. The 65-degree head angle and 77-degree effective seat tube angle keep the bike stable on aggressive descents and efficient on sustained climbs.

Why We Like It

C/Series carbon and a complete all-mountain spec.

Yeti's C/Series carbon uses the same size-specific layup philosophy as the TURQ frame to match stiffness and flex profiles consistently across the size run. Performance Switch Infinity V2 brings Yeti's next-generation translating pivot suspension design to this build, delivering the same active, efficient ride character found on higher-tier SB140 builds. Threaded BB with ISCG-05 tabs keeps the drivetrain interface durable and easy to service, with chain guide compatibility built in for more aggressive trail use.

Fox Factory Float X rear shock is a genuine upgrade over the Performance spec found on standard C2 builds, providing factory-level tuning and performance where it matters most in the travel. Fox Performance 36 fork handles the front end with 160mm of capable, tunable travel well matched to the SB140's geometry. Eagle 90 drivetrain runs a 10-52 cassette with a 30T chainring for full gradient coverage, and SRAM Maven Base brakes with 200mm front and 180mm rear rotors provide stopping power suited to the travel and terrain.

DT Swiss M1900 30mm alloy wheels are a durable platform with an upgrade path to XMC1700 carbon for riders who want to reduce weight down the road. Maxxis Minion DHF 2.5 front and DHR II 2.4 rear is an aggressive all-mountain tire pairing matched to the longer-travel character of this bike. OneUp dropper post is sized per frame for full-stroke use, and the UDH interface keeps future drivetrain upgrades simple.

Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
