What is a Drivetrain on a Bike?

A drivetrain is a collection of parts on a bike that allows you to pedal and propel the bike forward. It consists of the crankset, chainrings, cog set, cassette, shifters, and derailleurs.

The drivetrain allows you to adjust your gear ratio for different terrains so you can maintain an efficient cadence while riding.

When selecting components for your drivetrain it’s important to make sure they are compatible with one another in order to ensure smooth shifting performance.

Bicycle Drivetrain Systems

A bicycle drivetrain system is a complex network of components that work together to transfer energy from the rider’s legs to the wheels.

In most modern systems, this includes the chain and multiple sprockets on both sides of it, as well as shifters and derailleurs for changing gears.

This system helps riders go faster or tackle steeper hills with less effort.

Through proper maintenance and tuning, bike owners can maximize their ride experience by ensuring smooth shifting between gears whenever needed.

Bike Drivetrain Types

There are a few different types of drivetrains for bikes, including

  1. Derailleur systems,
  2. Internal gear hubs, and
  3. Single-speed systems

Derailleur systems are the most common type of bike drivetrain and feature multiple sprockets on the rear wheel that can be shifted with control cables to change gears.

Internal gear hubs (IGHs) offer more versatility than derailleurs as they allow riders to shift gears while stopped or coasting. However, they tend to be heavier than derailleurs and provide fewer overall gear options.

Single-speed systems don’t have any shifting mechanisms but may offer additional gearing options through the use of accessories such as freewheels or cog swaps.

What Side of the Bike is the Drivetrain?

When it comes to determining which side of the bike the drivetrain is on, it is important to consider the position of the drivetrain components. The drivetrain of a bike comprises several components. These components include the chain, crankset, chainrings, cassette, derailleur, and shifters.

Typically, the crankset and derailleur are located on the right side of the bike, while the cassette or freewheel is on the left side.

Therefore, the drivetrain is usually situated on the right-hand side of the bike, which means that the right-hand pedal is connected to the right-hand crank arm, which in turn is connected to the chainring.

As the rider pedals, the chain rotates around the chainring and passes through the rear derailleur to ultimately turn the rear wheel.

Understanding the position of the drivetrain is also essential for maintaining and repairing a bike. Regular maintenance of the drivetrain is crucial to ensure smooth shifting and maximum efficiency while riding.

This involves regular cleaning and lubrication of the chain and derailleur, adjustments to the derailleur alignment, and replacing worn-out components such as the chain or cassette.

Proper maintenance of the drivetrain not only improves the performance of the bike but also extends the lifespan of the components.

Therefore, it is recommended to get a professional tune-up from a bike shop at least once a year to keep the drivetrain in top condition.

What Are the Benefits and Drawbacks of Each Side?

The drivetrain of a road bike can be positioned on either the left or right side of the bike’s frame. Each position has its own benefits and drawbacks.

A drivetrain on the left side can provide improved stability and balance when navigating tight turns, while a right-side drivetrain can offer better acceleration and easier shifting.

However, a left-side drivetrain can be more difficult to service and maintain due to the limited availability of left-side components. On the other hand, a right-side drivetrain can be more prone to chain drop and derailment.

Let’s find the pros and cons of having a drivetrain on the left or right side below.

Pros & Cons Of Right Side Drivetrain

Having a drivetrain located on the right side of a road bike can offer both benefits and drawbacks. Here are some of the advantages and disadvantages to consider:

  • Easier shifting: Many riders find that shifting gears is easier and more intuitive with a right-sided drivetrain.
  • More efficient pedaling: The right-side drivetrain allows for a more direct chain line, which can enhance pedaling efficiency.
  • Reduced chain slap: With a right-sided drivetrain, the bike’s chain is less likely to slap against the frame, which can create noise and cause wear and tear.
  • Consistency with other bikes: Most road bikes have right-side drivetrains, which makes it easier to switch between bikes.


  • More difficult to initiate from a standstill: Starting from a stop on a right-side drivetrain can be challenging because the dominant leg is usually the left one.
  • Limited hand positions: The right-side drivetrain can limit hand positions on the right side of the handlebar.
  • Less visibility of the drivetrain: With a right-side drivetrain, you will find it a bit difficult to see the gear position of the rear wheel.

Pros & Cons Of Left Side Drivetrain

There are several benefits and drawbacks to having a drivetrain of a road bike on the left side.


  • Improved shifting efficiency: Since the left side of the bike is typically less cluttered and easier to access, shifting gears on the left side can be faster and more efficient.
  • Better weight distribution: By having the drivetrain on the left side, the bike’s weight is more evenly distributed, which can improve overall stability and handling.
  • Reduced chain slap: By positioning the chain on the left side, the risk of chain slap (where the chain hits the chainstay) is reduced.


  • Limited gearing options: By having the drivetrain on the left side, there may be limitations to the number and range of gears available.
  • Inconvenience for some riders: For riders who are used to having the drivetrain on the

Generally, pro cyclists prefer to use a right-side drivetrain for a number of benefits. Ultimately, the choice between a left or right-side drivetrain depends on the individual rider’s preferences and needs.

Drivetrain Bike Price

The price of a drivetrain bike depends on the type, quality, and components included.

Generally speaking, you can expect to pay anywhere from $400-$3000 for a good quality drivetrain bike.

Higher-end models with more features can cost up to $5000 or more.

Ultimately, it’s important to research different brands, compare prices and find the best value for your budget before making a purchase decision.

Q-1: Which Side of the Bike is the Drive Side?

When it comes to bicycles, it can be confusing to know which side is the drive side. Many people are unfamiliar with basic bicycle terminology and don’t understand that there is a “drive” side of the bike.

The drive side is the right-hand side of your bicycle when you look at it from behind.

This includes all components related to power transfer such as pedals, chains, cogs, and rear sprockets. All these parts are important in propelling your bike forward when you pedal hard enough! It also houses more complex parts like derailleurs and shifters if your bike has them installed.

The drivetrain on a modern mountain or road bike will usually consist of several chainrings (front cog) connected by one or more derailleurs to the cassette (rear cog). These pieces all work together to provide varying levels of gearing for different terrains and speeds while pedaling.

Knowing which side of your bicycle is considered the drive side can help you identify potential issues quickly since all power-related components are located here.

With this knowledge, riders can easily spot any worn-out or damaged parts before they cause bigger problems down the line!

Q-2: What Part of the Bike is the Drivetrain?

The drivetrain of a bicycle is the system that propels it forward. It includes all the components between the pedals and rear wheel, such as cranks, chainrings, chain, cassette, derailleurs, and shifters.

The drivetrain is an essential part of any bike because it provides power to move you along while cycling.

Q-3: What is the Left Side of a Bike For?

The left side of a bike is typically used for the gear shifter. The gear shifter allows you to change gears as you ride, allowing you to go faster or slower depending on your needs.

This is done by pushing the lever up and down while pedaling in order to switch between different gears.

Depending on what type of bike you have, this lever may be located on either the top tube or handlebar near your left hand.

The other component that can sometimes be found on the left side of a bike is the brake lever, which will allow you to slow or stop your bike when necessary.

When riding a road bike, it’s important to keep both hands firmly gripping their respective levers so that you can quickly react if needed.

Q-4: Is There a Left Handed Bike?

Yes, there is such a thing as a left-handed bike! This unique bicycle allows riders to mount and ride the bike from their left side, rather than the traditional right.

It’s especially beneficial for those who are naturally more comfortable or experienced with riding on their non-dominant side.

Left-handed bikes also provide an excellent workout for both sides of your body since you’ll be using muscles in both arms and legs to pedal and steer simultaneously.

The handlebars are placed so that your hands can rest comfortably on them while keeping a good posture throughout the ride. And because it has two brakes, one on each side, you won’t need to reach over when needing to stop quickly – making it much safer too!

All in all, if you’re looking for something new and different in biking then this could be just what you’re looking for.

Drivetrain: derailleurs, chain, and chainrings – how do they work?


In conclusion, what side of the bike is the drivetrain on can depend on the type of bicycle you have. A regular two-wheeler will usually have it on the right side, while a mountain or electric bike may have it on either side.

Ultimately, if you’re unsure which side your drivetrain is located on, consult your owner’s manual for more information and guidance.
