Whether your finish line is on the race course or at your front door, the Bontrager Circuit MIPS road bike helmet delivers the performance, comfort and protection you need for 2-wheeled adventures.

  • Features

    • Rotational motion can cause brain injuries; with MIPS, a low-friction layer slides 10 to 15mm in all directions, reducing rotational motion to the brain during impact
    • Integrated Blendr mount lets you attach an action camera or Bontrager light accessory (not included)
    • Boa® closure system lets you easily secure and adjust your fit with just 1 hand
    • In-mold composite skeleton increases helmet integrity for larger vents and increased airflow
    • AgION antimicrobial pads wick moisture and inhibit the growth of odor-causing bacteria
    • LockDown dividers make helmet strap management clean and easy to adjust
    • Internal, recessed channels move airflow over your head to help you stay cool and dry
    • Bontrager offers a Crash Replacement Guarantee, providing free helmet replacement if involved in a crash within the first year of ownership


    To find your size, position a tape measure just above your ears and about 1 in. above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Technical specs info.
