Description
The LS is Factor’s purpose-built gravel race bike — light, responsive and designed to perform across mixed terrain. Its carbon frame balances stiffness and comfort, with geometry suited for everything from long-distance adventures to full-speed race days.
Stripped of gimmicks and excess, the LS focuses on what matters most: speed, efficiency, and ride quality. It’s designed to ride like a road bike when you want it to, and handle rough stuff when you need it to. Precision handling, clean lines and clearance for up to 43 mm tires—it’s all here, dialed and refined.
Whether you’re lining up at Unbound or hammering local dirt roads, the LS delivers.
