  • The frame features an A1 Premium Aluminum construction that provides the ideal blend of efficiency and durability, while the geometry creates a roomy top tube and short chainstays for easy climbing and confident descending.
  • Our A1 Premium Aluminum fork is lightweight and pairs up perfectly with the fat wheel system to soak up trail chatter and bumps.
  • Our Fatboy alloy rims serve as the foundation of a wheelset that's dependable, rugged, and efficient. So whether Junior is doing some trail riding or plowing through the snow, these wheels will be the perfect mix of performance and strength.
  • 20x.4.0" Ground Control tires help soak up bumps, while also providing crazy levels of traction, control, and floatation for better handling out on the trail.
  • A forged alloy crankset will take a licking, while a chainguard has also been added to make sure that Junior's laces or pants keep clear of the drivetrain.
