Shimano's STI shifters (Shimano Total Integration) combines the shifting mechanism into the brake levers. This system of bicycle shifting replaces downtube shifters on many road bicycles. Using the STI shifter requires learning the delicate balance of getting the gear shifting without engaging the brakes, and vice versa. To learn the STI method takes about five to 10 minutes of pedalling practice.

  1. 1

    Mount the bicycle and place your hands onto the drop bars and the STI shifters, which look like the brake levers.

  2. 2

    Begin pedalling and riding. Push the right-hand STI lever inside to shift the gears off the rear cassette up. Keep pedalling and pushing the shifter until you cycle through the full gear range.

  3. 3

    Grip the lever gently and pull it into the bicycle to brake. Begin pedalling again and push the lever to the outside of the bicycle to shift down until the full range of gears has been shifted.

  4. 4

    Pedal farther and push the left-side STI shifter in toward the bicycle. Feel for the chain-ring to move the chain one full ring up. If you have a three-ring crank and chain-ring system, push the lever once more to the inside. Continue pedalling and push the lever to the outside to shift down on the chain rings.

  5. 5

    Grip the brake/STI lever on the left-side and pull it in toward the front of the bicycle and feel the front brake engage.
