The Tern Surge Pro delivers the performance of a modern road bike, with the footprint of a classic Japanese minivelo. Featuring classic drop-bars, internal cable routing, and a 451 Kinetix wheelset, every design decision has been optimized for speed. To top it off, we spec’d an ultra-light aero carbon fork.

  • 451 minivelo design for urban maneuverability and portability
  • Short-reach dropbar with Shimano 105 STI levers for integrated shifting precision
  • Full carbon Kitt Design fork, for speed and comfort
  • Smooth welded aero-edge tubing for a bold and aggressive ride
  • Internal cable routing for clean body-lines
  • 451 wheels
