Built for speed, optimized for 35– 46mm tires. UP 2.0 follows the iconic original U.P. that defined the modern gravel bike category a decade ago — now with crisper handling for everything from fast group rides to tough bikepacking trips.

  • OPEN BAR cockpit — integrated handlebar/stem with 15mm of micro-stem length adjustment in 5mm steps.
  • Size-specific frame design for consistent handling across every size.
  • U-Turn Aero fork — OPEN's fastest fork.
  • Chassis includes: frame, fork, headset, seatpost, and integrated handlebar/stem.
