The best thing in-between sliced bread.

The all-new PBJ was redesigned from the ground up, now featuring an aluminum frame, new geometry and added features. The hydro-formed 6061 aluminum frame allowed us to build in the features that riders need for the level of riding today, unlocking extremely short chainstays and low standover height. The geometry and sizing has evolved to provide a quick and responsive feel, to help pump through corners and pull back off the steepest of lips. For riders seeking to find their flow riding dirt jumps, skate park, and pump track, look no further, the PBJ is here to pump, bump and jump everything in sight. Now available in two sizes, short and standard, to best suit rider's needs.

Features:

  • Short
    The "Short" size was designed not only for shorter humans, but also to complement riders looking for a precise feel that allows for ultimate creativity. This size may just help you land that next rotation, boost out of the quarter pipe, or nail the trickiest of manual lines with a 377 - 395 mm chainstay length and 395 mm reach.
  • Standard
    The "Standard" size is best for riders looking to sharpen their skills at the pumptrack, or prefer a more stable geo for bigger jumps and higher speeds without sacrificing the playfulness of the short rear end. This size has the same 377 - 395 mm chainstay length as the short, and is paired with a 420 mm reach.
  • Hydro-Formed 6061 Aluminum
    The all-new new frame is made of hydro-formed 6061 aluminium, known for its high strength to weight ratio, and smooth look. It's both simple and refined, all while keeping it light. The design keeps things compact with a low standover height, giving you a feeling of effortless control with room to move. The clean lines create a modern vibe with a laid-back, minimalist style that fits in at the dirt jumps, skate park or pumptrack.
  • Chain Tensioners
    Integrated chain tensioners make it easy to fine tune your chain tension and keep the rear wheel aligned in your frame. These work with all 10x135 hubs and are easy to adjust with the tool-less design.
  • Cable Routing
    Internal or external cable routing allows you to have it your way. Run your brake cable internal for a clean and tidy look, or external to make brake swaps simple as well as give gyro capability.
