What Is The Lightest Crankset For A Road Bike? A Guide For Cyclists

What Is The Lightest Crankset For A Road Bike

Cycling is a great way to exercise, explore new places, and meet new people. However, if you’re not using the right crankset for your bike, you’re likely not getting the most out of your cycling experience.

A crankset is a bicycle component that allows you to rotate the pedals. It’s typically metal and has two arms connecting to the pedals. When you pedal, the arms move the pedals around, which turns the wheel.

But what is the lightest crankset for a road bike? Here we’ll discuss the different types of cranksets, their benefits, and drawbacks, and help you choose the right one for your cycling needs. We’ll also provide a guide on measuring your pedal power and choosing the right crankset for your bike. So read on to learn about the lightest crankset for a road bike.

What Is A Crankset?

What Is A Crankset

A crankset is a pedal-powered mechanism that helps you turn bike pedals. It comprises several parts, including the chain, chainring, and crankarms. The chain links with the ring to create a rotating motion to power the pedals. Road bikes are unique machines. They require a different crankset than what is typically found on mountain bikes.

A crankset is the engine of a road bike, and it converts the power from your pedals into rotational motion. There are many different types of cranksets available, each with different characteristics.

  • A crankset is a crucial component of a bicycle’s drivetrain system.
  • It converts the rider’s pedalling motion into rotational power, which propels the bicycle forward.
  • The crankset consists of one or more chainrings attached to a set of crank arms mounted to the bicycle frame via the bottom bracket.
  • The chainrings come in different sizes, which affect the gearing and overall speed of the bicycle.
  • The crankset is an essential part of the bicycle that needs to be chosen carefully based on the rider’s needs and intended use.

Types Of Cranksets

Types Of Cranksets

There are several cranksets available on the market that are designed to be lightweight for road bikes. Some lightest options include carbon fiber cranksets from brands like Shimano, Campagnolo, and SRAM. Ultimately, the lightest option will depend on your specific needs, preferences, and budget. It is important to note that while a lighter crankset can improve your bike’s overall weight and performance, it may have some drawbacks, such as reduced durability and increased cost.

  • The most common type is the Shimano crankset, found on most bicycles. It’s a standard setup that uses two chainrings to convert the rotation of your pedals into a rotary motion that goes into your bicycle’s rear wheel.
  • The second type of crank is the single-ring crank, mostly used for mountain biking or BMX racing. This type of crank uses just one ring, which means you must pedal very hard to make it move. It’s less efficient than the Shimano crankset but can be more challenging and fun.
  • The third type of crank is the three-ring crank, which is rarely used in traditional cycling because it’s inefficient. However, it’s popular among riders who want to use triple gears or Internal Combustion Engine (ICE) bikes. These riders use three rings on their cranks for extra power and speed when needed.

Benefits and Drawbacks

There are a few different types of cranksets, each with benefits and drawbacks. One of the most common types of cranksets is the standard crankset. It consists of two chainrings, typically in sizes of 39 teeth and 53 teeth, and is ideal for road biking and racing.

Standard cranksets offer a wide range of gear ratios, which allow cyclists to maintain a consistent cadence while riding on flat roads, climbing hills, or sprinting. However, standard cranksets may not be suitable for all riders, especially those who prefer a more relaxed riding style or those not used to high gear ratios.

In contrast, compact cranksets have smaller chainrings, usually with sizes of 34 and 50 teeth, and are better suited for recreational riders and beginners. Compact cranksets offer a lower gear range, which makes it easier to climb hills and maintain a comfortable

Selecting the right crankset for your road bike cannot be overstated. The size and number of chainrings will depend on the type of riding you plan to do and your fitness level. A higher number of chainrings will provide more gear options, allowing you to tackle steeper hills and maintain a higher speed on flat terrain.

Additionally, the size of the chainrings will determine the gear ratio, affecting the force required to pedal and the speed at which you can ride. Therefore, selecting the right crankset is crucial in optimizing your road bike’s performance and maximizing your riding experience.

When shopping for a crankset for your road bike, it’s important to consider a few key factors.  Some critical features for selecting a lightweight crankset include increased durability and decreased weight. Here are some information about what is the lightest crankset for a road bike:

Gravitas Gen 13 Crankset

Gravitas Gen 13 Crankset

The Gravitas Gen 13 cranks use advanced carbon-fibre construction and weigh only 279g. For a complete crankset, they include a 50T chainring, 24T ring, and 11-36T cassette. This makes them the lightest option on the market and compatible with most road bikes.

They’re made from high-quality materials, so you can be sure they’ll last longer and deliver great performance. In addition, their compact design means they’ll fit easily into your bike’s frame, so you won’t have to spend extra time installing them. Why this crankset is good?

  • The first factor is the material of the crankset. Generally, cranksets made from carbon fiber or aluminium tend to be lighter than steel ones. However, it is important to note that carbon fiber cranksets are often more expensive than aluminium ones. In addition, carbon fiber can be more brittle than aluminium, making it more prone to damage if mishandled.
  • Another factor to consider is the number of chainrings on the crankset. Single chainring cranksets tend to be lighter than double or triple chainring cranksets. However, single chainring cranksets may not be suitable for riders who require a wider range of gears. Double and triple-chainring cranksets provide a wider range of gear options, but these options come at the cost of added weight.

How To Choose The Right Crankset For Your Bike?

How To Choose The Right Crankset For Your Bike

When shopping for a new crankset, the arm’s weight is one of the most important factors. Road bikes typically require heavier crankarms than mountain bikes, so choosing a lighter option is important if you plan on riding primarily on paved roads.

Other factors to consider are the frame size, geometry, and gear range you need. If you’re unsure which crankset is right for your bike, consult an expert or online resources like Crank Fiend. Ultimately, the best way to find the lightest crankset for your road bike is to experiment and find the best option that fits your needs.

1. Determine your bike’s bottom bracket type – before choosing a crankset, you must know your bike’s bottom bracket type. There are several types of bottom brackets, including square taper, external threaded, press-fit, and BB30.

2. Consider the crank arm length – the length of the crank arm affects your pedaling efficiency. Therefore, it’s essential to choose the right length that suits your riding style.

3. Choose the right number of chainrings – the number of chainrings on your crankset will depend on the type of riding you plan to do. Road bikes typically come with two chainrings, while mountain bikes have three.

4. Determine the bolt circle diameter (BCD) – the BCD is the distance between the bolts that hold the chainring to the crank arm. It’s essential to choose a crankset with the right BCD to ensure compatibility with your bike.


Ultimately, we must say that getting the lightest crankset is something you cannot afford to miss out on. With lighter and faster options, choosing one can be time-consuming. To save you time, we outlined facts on what is the lightest crankset for a road bike. Whether you’re a beginner cyclist or an experienced rider, choosing the right crankset for your bike is essential.
