Trail-ready value defines the Yeti SB120 C2 Eagle 90 Mountain Bike
What Our Gearhead® Experts Are Saying:
"The SB120 C2 is the most accessible way into Yeti's Switch Infinity suspension platform without feeling like a compromise. The Fox Performance fork is well-tuned, the Eagle 90 drivetrain shifts reliably, and the frame geometry is pure SB120."
Who It's For
Trail riders ready to step into a full-carbon Yeti build.
This bike suits intermediate riders who want a proven full-suspension trail bike with quality components and room to upgrade. It's a strong choice for those moving up from an entry-level bike who want a chassis that assists their progression.
What It's For
All-day trail riding on singletrack with a mix of climbing and technical descent.
The SB120 C2 handles flowy trail and technical singletrack with equal confidence. It climbs efficiently and descends capably, making it a practical choice for riders who ride often and hard.
Why We Like It
Switch Infinity suspension and carbon construction.
Yeti's C/Series carbon frame brings Switch Infinity V2 suspension without changing the geometry or ride character. Fox Performance Float suspension front and rear is tunable and capable. Eagle 90 drivetrain covers the full range of trail gradients reliably.
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.
