Mountain bikes require brake and gear adjustments on the trail because the cables attached to the brakes and gears tend to get stretched, causing them to loosen. Making an adjustment on the trail requires taking a moment to apply the following these steps.

Difficulty: Moderate
Instructions

    Adjust Front and Rear Brakes

  1. Step 1

    Locate the barrel adjusters for the brakes at the front left handle of your bike for the front tire and the right front handle for the back tire brake.

  2. Step 2

    Place your fingers on the barrel adjusters while squeezing the brake handle down.

  3. Step 3

    Adjust the barrel with your fingers, turning the barrel left or right and feeling the barrel tighten or loosen.

  4. Step 4

    Determine which direction tightens the barrel, and then go that direction to tighten the cables. Continue with the other brake handle, performing the same adjustment to the barrel.

  5. Adjust the Gears

  6. Step 1

    Locate the cable to your gear housing.

  7. Step 2

    Place your fingers on the knob of the gear shifter while holding the gear cables.

  8. Step 3

    Turn the shifter left and right until you notice which turn tightens the knob. Turn the knob about a quarter turn to tighten the gear knob.

  9. Step 4

    Hold the gear cable after adjusting the knob. If it feels tighter, that's all you need to do. The gear cable works better now.

  10. Step 5

    Find your rear derailer at the back tire.

  11. Step 6

    Lift the protective cover off the rear gear adjuster to get to the barrel adjuster.

  12. Step 7

    Turn the barrel adjuster left or right very carefully until you notice more tension.

Tips & Warnings
  • All mountain bike control their brakes and gears through cables.
  • Turning the shifting knob for your gear housing improves your gear shifting when you ride on the trail.
  • Make an adjustment to your brakes and gears when the cables stretch out and prevent proper braking gear changes to your mountain bike on the trail.
  • Make sure you don't tighten the cables too much. Simply rotate each tire of the brake handle you tightened. The tire needs to rotate smoothly without a rubbing sound.
