Kroka’s mountain biking and bikepacking programs require high-performing bicycles that meet certain specifications to ensure a safe and successful journey for all involved. This page contains some useful information about the specifications of a trail-ready bicycle.

You are welcome and encouraged to bring your own mountain bike to a Kroka bike program or semester. Please ensure bikes meet the following criteria:

  • FRAME: steel or aluminum, sized appropriately to the student.
  • SUSPENSION: front suspension is preferred; full suspension bikes are acceptable for one-week summer programs but not for bikepacking/expedition programs, including Semesters.
  • TIRES: 27.5 – 29″ wheels with trail-ready tires, 2.4″ minimum (2.6-3.0″ tires preferred). For SEMESTER ONLY: Tires must be new–or have very little use–and be tubeless.
  • BRAKES: disc brakes
  • GEARS: 10 speed minimum
  • PEDALS: platform pedals with spikes

Bikes must be professionally tuned before coming to Kroka so they are ready to ride! If you are bringing a bike from home, please upload a photograph of your bicycle to your Portal so our biking staff can make sure it is suitable for the program.
