Yeti Cycles SB120 C2 Eagle 90 Factory Mountain Bike

Trail-defining capability meets featherweight control in the SB120 C2 Eagle 90 Factory

What Our Gearhead® Experts Are Saying:

"This SB120 hits that sweet spot for aggressive XC and trail—nimble, fast, and big enough to hold up in rowdy terrain. The Factory suspension upgrade takes it to another level with plush, reactive control I noticed immediately on loose descents."

We love when a bike challenges categories, and the Yeti SB120 C2 Eagle 90 Factory does just that. Designed around a short-travel platform but tuned for all-day trail punishment, this setup is an ideal blend of efficiency and capability. The SB120’s C/Series carbon frame with Switch Infinity suspension gives us that crisp Yeti ride feel with the weight savings we crave when climbing.

This frame platform was built to support confident descending too—thanks to its 66.5-degree head tube angle and progressive leverage curve. Internally routed cables, a threaded BB, and high-clearance downtube make maintenance low-effort, while sealed Enduro Max bearings and UDH compatibility give us peace of mind for years to come.
