Ride with confidence on the toughest trails in the Bontrager Rally MIPS mountain bike helmet. With MIPS technology, a Boa® closure and ample vents, it offers comfort and protection for any ride.

  • 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
    • Boa® closure system lets you easily secure and adjust your fit with just 1 hand
    • Integrated Blendr mount lets you attach an action camera or Bontrager light accessory (not included)
    • Drop-in coverage on back of helmet offers extended protection
    • In-mold composite skeleton increases helmet integrity for larger vents and increased airflow
    • FlatLock dividers make helmet strap management simple with a fixed-position fit
    • 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" 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.
