What is a Chainstay on a Bike? (Easy Explained)

A chainstay is a part of the bike frame that holds the rear wheel and connects it to the bottom bracket. It’s also called a rear dropout.

Chain stays are typically made of steel or aluminum, but they can also be made out of carbon fiber. Chain stays are used in mountain bikes, cyclocross bikes, and road bikes.

A chainstay is attached to the bottom bracket and supports both wheels by connecting them to each other at the center point of their respective frames. The most common type of chain stay is round but there are also square and diamond-shaped chain stays as well.

In this article, I will discuss what is a chainstay on a bike and how it can affect your riding experience.

What Is A Chainstay? [Bike Chainstay]

A chainstay is also known as a “chain stay” or “chain stay bridge”. Is a pair of steel, aluminum, or carbon fiber tube for the bike frame that connects the bottom bracket to the rear dropouts. It is a crucial part of the bike as it acts as an anchor for the bicycle’s gears, brakes, and crankset.

What Is Chainstay Length?

Chainstay length is the distance from the center of the bottom bracket to the center of the rear dropouts. It is measured in inches or centimeters and it is an important measurement because it determines your bike’s geometry.

Chainstay lengths range from 16 inches to 18 inches on most road bikes, with most bikes falling within this range. The exception is mountain bikes that have much shorter chainstays than road bikes because they have less suspension travel and are designed for speed rather than comfort or stability.

Where Is The Chainstay On A Bike?

The chainstay is located between the bottom bracket and the rear wheel. The chainstay is typically made of aluminum or steel, but sometimes titanium or carbon fiber may be used. The material that is used for the chainstay varies depending on what type of bike it is and what purpose it was made for.

What Is The Function Of Chainstay?

Chainstay has two functions: it provides support for the rider when pedaling and it also helps to keep the chain from slipping off. But, it is mainly used to secure the back wheel in place.

A chainstay is a part of a bicycle frame that helps keep the back wheel in place by securing it on either side of the seat tube or down tube with two or more rods connected by a chain.

Why Is Chainstay Length Important?

Chainstay length is an important factor in bicycle design. It’s the distance from the bottom bracket to the center of the rear axle, and it’s a direct result of how many chainrings you have. Chainstay length can be thought of as your bike’s wheelbase since it affects stability and handling, as well as tire clearances.

Chainstay length is also an important factor in determining how much power your bike can absorb while pedaling. This is because longer stays allow more power to be transferred from your legs to your rear wheel, which means you can go faster with less effort.

Chainstay length is important because it affects how well your bike pedals, how much power it transfers from your legs to the wheel, and how stable it feels when you ride it.

Is Chainstay Necessary?

Yes, the Chainstay is necessary. Remember that the chainstay is a part of the bike frame that connects to the rear wheel. It is designed to help cyclists remain stable and in control during turns, drops, and jumps.

The chainstay is a bike component that helps to prevent the wheels from slipping when you are riding at high speed. In order to keep your wheels from slipping, you need to have a chain stay on both sides of the bicycle.

What Is A Good Chainstay Length?

A good chainstay length for bicycles is typically between 40 and 45 centimeters, or about 16 to 18 inches. Also, we can say that a good chainstay length is one that allows for efficient pedaling while also providing enough stability to prevent wheel hop.

A short chainstay will be more responsive and agile, whereas a long one can be more stable but less responsive.

It is important to have a good chainstay length because it will help the rider maintain balance and avoid injuries.

What does a shorter Chainstay do?

The shorter your chainstay length, the more responsive your bike will be to changes in power output – meaning that it will react faster to input and it has better traction.

A shorter chainstay length provides more stability and easier pedaling, but it can also make for a less comfortable ride if you are not used to it.

A shorter chainstay also allows you to move your weight back and forth in a more efficient way.

What does a longer chainstay do?

The longer chainstay of a bicycle allows for greater stability when riding at speed, especially on rough terrain. It also makes it easier for riders to steer with one hand, as it lessens the distance between the hands and the front wheel.

A longer chainstay allows for more vertical travel, which means you have more control over your bike when you are climbing up and down hills.

What Is Chainstay Angle On A Bike?

Chainstay angle refers to the angle between the rear axle and the chainstay. The chainstay Angle determines how much room a bike has for your legs. The angle of this triangle determines whether it will be comfortable or not when riding.

It also affects how much power you can put into your pedal stroke, which can make or break your ride depending on what you’re looking for in a bike.

Why Are The Two Chainstay Tubes Not Made Equally?

The reason there is a difference in length between the two chainstay tubes is that the chain side chainstay connects the drive and chain to the rear axle, so it is a heavier tube than the left side which only connects the pedal to the rear axle.


Q. How does chainstay length affect the ride?

Chainstay length affects ride quality by determining how much power can be applied to pedaling, and how much force is transmitted to the rear wheel. The longer the chainstay length, the more power can be applied to pedaling, and greater force will be transmitted to the rear wheel.

A shorter chainstay length will give you better maneuverability at high speeds, while a longer one will give you better stability at high speeds.


In conclusion, the chainstay is one of the most important parts of a bike. It is the part that connects to the frame. The chainstay on a bike can be thought of as an extension of the bottom bracket. It helps to absorb some of the forces from pedaling and pushes back against them.
