How To Use Gears On A Mountain Bike

Written by John Tomac

Gears on a mountain bike, also known as the drivetrain, are used to adjust the pedaling resistance of the bike to match the terrain and the rider’s personal comfort level. The drivetrain consists of a chain, chainrings (located at the front of the bike), cogs (located at the rear of the bike), and the shifting mechanism (usually located on the handlebars).

When you pedal a mountain bike, the chain wraps around the chainrings and cogs to turn the rear wheel and propel the bike forward. By adjusting the position of the chain on the chainrings and cogs, you can change the gear ratio, which determines how much resistance you feel when you pedal. A lower gear ratio (easier gear) will provide less resistance, making it easier to pedal, while a higher gear ratio (harder gear) will provide more resistance, making it more challenging to pedal.

Most mountain bikes have multiple gears, which can be shifted using the shifting mechanism on the handlebars. The left-hand shifter is typically used to adjust the position of the chain on the chainrings, while the right-hand shifter is used to adjust the position of the chain on the cogs. By shifting the gears, you can fine-tune your pedaling resistance to match the terrain and your personal comfort level.

Understanding how to use the gears on your mountain bike can greatly improve your riding experience by allowing you to pedal more efficiently and comfortably. By shifting to an easier gear when climbing a hill and a harder gear when descending or riding on flat terrain, you can maintain a consistent pace and avoid feeling overworked or underutilized. With practice and experience, you’ll become proficient at using your mountain bike’s gears to enhance your rides.

Understanding the Driveterrain

The drivetrain of a mountain bike refers to all the components that are involved in transferring power from the pedals to the rear wheel. These components work together to allow the rider to adjust the resistance they feel when pedaling, or the gear ratio, to match the terrain and their personal comfort level.

The chain is a loop of metal links that connects the front chainring to the rear cog, or sprocket. The chainring is a toothed ring located at the front of the bike, and the cog is a toothed wheel located at the rear of the bike. The combination of chainrings and cogs determines the gear ratio.

The cassette is a stack of cogs that are mounted on the rear wheel hub. Most mountain bikes have cassettes with up to 11 cogs, which provide a wide range of gear ratios to choose from.

The derailleur is the mechanism that moves the chain between the chainrings and cogs when you shift gears. It consists of a cage and two pulleys that guide the chain as it moves. The derailleur is controlled by the shifters, which are levers located on the handlebars. The left-hand shifter controls the front derailleur, which moves the chain between the chainrings, while the right-hand shifter controls the rear derailleur, which moves the chain between the cogs on the cassette.

Together, these components make up the drivetrain of a mountain bike and allow the rider to fine-tune their gear ratio to match the terrain and their personal comfort level.

How Do Bicycle Gears Work?

Bicycle gears work by allowing you to adjust the resistance you feel when pedaling, or the gear ratio. The gear ratio is determined by the combination of the chainring (located at the front of the bike) and the cog (located at the rear of the bike).

When you pedal a bike, the chain wraps around the chainring and cog, turning the rear wheel and propelling the bike forward. By changing the position of the chain on the chainring and cog, you can adjust the gear ratio and alter the resistance you feel when pedaling.

For example, if you shift to a smaller chainring or cog, the gear ratio will become easier, and you will feel less resistance when pedaling. This is useful when climbing hills, as it allows you to maintain a steady pace without overworking your legs. On the other hand, if you shift to a larger chainring or cog, the gear ratio will become harder, and you will feel more resistance when pedaling. This is good for descending or riding on flat terrain, as it allows you to maintain a higher speed without feeling underutilized.

Most bikes have multiple gears, which can be shifted using the shifting mechanism on the handlebars. The left-hand shifter is typically used to adjust the position of the chain on the chainring, while the right-hand shifter is used to adjust the position of the chain on the cog. By shifting the gears, you can fine-tune the gear ratio to match the terrain and your personal comfort level.

Overall, bicycle gears work by allowing you to adjust the resistance you feel when pedaling to match the terrain and your personal comfort level. By using the gears effectively, you can pedal more efficiently and comfortably.

When To Shift Gears On an MTB

There are a few general guidelines for when to shift gears on a mountain bike:

  1. Shift to an easier gear before you start climbing a hill. This will make it easier to pedal and help you maintain a steady pace. To shift to an easier gear, use the left-hand shifter to move the chain onto a smaller chainring or cog.
  2. Shift to a harder gear when you’re descending or riding on flat terrain. This will allow you to pedal more efficiently and maintain a higher speed. To shift to a harder gear, use the right-hand shifter to move the chain onto a larger chainring or cog.
  3. Use the right-hand shifter to fine-tune your gear ratio as you ride. For example, if you’re pedaling too hard on a climb, you can use the right-hand shifter to move the chain onto a smaller cog to make it easier to pedal.
  4. Use the left-hand shifter to make major adjustments to your gear ratio. For example, if you’re approaching a steep hill, you may need to shift to a smaller chainring to make it easier to climb.
  5. Pay attention to your cadence, or the number of times you pedal per minute. A higher cadence (around 90 rpm) is typically more efficient, especially on flat or rolling terrain. You can adjust your cadence by shifting to a harder or easier gear as needed.
  6. Shift your gears smoothly and avoid shifting under heavy load. Shifting under load can cause damage to your chain and drivetrain. It’s best to shift gears when you’re pedaling lightly or not pedaling at all.

By following these guidelines, you’ll be able to use your mountain bike’s gears effectively to improve your riding experience. Keep in mind that every rider is different, and the ideal gear ratio will depend on your personal preferences and the terrain you’re riding on
