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.
Upgrades
  • This bike combines lightweight carbon with versatile enduro geometry.
Features
  • Curious about one of the biggest perks of buying with TPC? Read about our Guaranteed Buyback Program. It comes standard with every bike we sell.
Master Mechanic’s Notes
  • Small paint chips on the top tube & non-drive side down tube.
  • Moderate paint chips on the seat tube.
