A Love Letter to Trails

Why We Love It
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. YT built the frame to be stiff and bombproof to withstand hit after hit.
Master Mechanic’s Notes
  • Light scratches on the rear brake lever & rear derailleur
  • Light scratches on the fork lowers, top tube, rims, & rear triangle
  • Moderate scratches on the crank arms
