How to Install Aerobars

Aerobars are a type of bicycle handlebar cyclists commonly use in time trials and triathlons. The basic design includes two bars that extend out over the front wheel. The position of the bars forces the cyclist to maintain a low, aerodynamic position while piloting the bicycle. The position is crucial when trying to shave precious seconds off of overall time. Clip-on aerobars attach to the current handlebar setup, and cyclists can adjust the bars following installation to suit their preference.

Instructions

    • 1

      Loosen the two bolts at the clamp-end of each aerobar using a 5-mm hex key. Separate each clamp plate from its respective aerobar.

    • 2

      Apply bicycle grease to the threads of each bolt. Use your fingers to cover the threads entirely. Remove any excess grease.

    • 3

      Place the left aerobar clamp onto the handlebar flush against the left side of the handlebar stem. The handlebar stem connects the handlebar to the rest of the bike.

    • 4

      Fit the clamp plate onto the aerobar clamp. Thread each bolt in by hand.

    • 5

      Place the aerobar even with the ground. Use the hex key to tighten each bolt, but just enough to keep the aerobar from slipping.

    • 6

      Install the right aerobar flush against the right side of the stem. Again, tighten the bolts just enough to keep the bar from slipping.

    • 7

      Adjust the aerobars so that they are horizontal with the ground. Most importantly the two bars should be even with one another. If available, place a bubble level across the two bars to check if they are perfectly parallel with one another.

    • 8

      Tighten each clamp bolt fully and evenly, following any needed adjustment.

    • 9

      Take the bicycle for a test run. If the new aerodynamic position feels severe, consider loosening the clamp bolts are raising both bars a fraction. Always tighten bolts securely following any adjustment.
