Overview
About this bike
Roscoe 8 is a trail hardtail for anyone looking to have some serious fun on the dirt. 29er wagon wheels smooth out rocks and roots, grippy 2.6" tires give you a boost in traction, and a 140mm suspension fork make it a blast on every trail, from packed singletrack to the loose stuff. It's a laid-back trail mountain bike dressed in a high-quality spec that's ready to party.
