About the Jeffsy 27 CF

A Love Letter to Trails

• Balanced geometry excels on rides with lawless descents and plenty of climbs
• Overbuilt frame is stiff and can pound through hit after hit
• Low-slung frame and long wheelbase are stable at high speeds
• Flip chip changes geometry to suit your particular challenges
• Mid-travel is composed through all types of riding

The Jeffsy is a go-anywhere, do-anything kind of bike. Its head tube angle, long wheelbase, and low bottom bracket all point towards absolutely crushing descents. Yet the steep seat tube puts you right over the pedals for powerful and efficient climbing too.
