Bike pedals come in various sizes, which are measured using specific standards. The most common pedal sizes include 9/16 inches x 20 TPI, 0.5 inch x 20 TPI, and 0.55 inches x 20.32 TPI.
These measurements might sound technical, but they determine how your pedals connect to the crank arms.
Let’s break down these common pedal sizes to understand what they mean and how they impact your cycling experience.
This is the most prevalent pedal size, found on the majority of bikes.
The “9/16 inches” refers to the diameter of the pedal’s threaded area.
“20 TPI” stands for “threads per inch,” indicating the number of threads wrapped around the pedal’s spindle.
Example:
Imagine a pedal with a 9/16 inches x 20 TPI size. This means the threaded part that attaches to the crank arm has a diameter of 9/16 inches, and there are 20 threads for every inch of the pedal’s length.
Less common but still used on some bikes.
The “0.5 inch” represents a smaller diameter compared to the standard 9/16 inches.
“20 TPI” indicates the same thread density as the previous size.
Example:
Picture a pedal with a 0.5 inch x 20 TPI size. In this case, the threaded part has a smaller diameter of 0.5 inch, with the same 20 threads per inch.
A slightly larger diameter than the standard 9/16 inches, offering a unique fit.
“0.55 inches” is the diameter of the threaded section.
“20.32 TPI” indicates a slightly higher thread count, allowing for a finer connection.
Example:
Envision a pedal with a 0.55 inches x 20.32 TPI size. This means a larger threaded diameter of 0.55 inches and approximately 20.32 threads per inch.
When it comes to mountain biking, every detail matters, and that includes the thread directions of your bike pedals.
The thread direction of your pedals determines how they are installed on your crank arms.
We are demystifying the technical jargon and providing you with practical insights to make the right choices for your off-road escapades.
Before we delve into the specifics, let’s grasp the fundamental concepts,
Pedal threads have a unique design to prevent the pedals from accidentally unscrewing while you ride.
Each pedal has a specific thread direction to ensure they stay securely attached to the crank arms.
The two main types of pedal thread directions are known as “right-hand thread” and “left-hand thread.”
This terminology refers to the direction in which you turn the pedal to tighten or loosen it.

The majority of mountain bike pedals use the right-hand thread direction.
Here’s what you need to know.
To install a right-hand thread pedal, you turn it clockwise (to the right) to tighten it onto the crank arm.
To remove a right-hand thread pedal, you turn it counterclockwise (to the left) to loosen it.
Some mountain bike pedals, often found on the left side, use the left-hand thread direction.
To attach a left-hand thread pedal, you turn it counterclockwise (to the left) to tighten it onto the crank arm.
To take off a left-hand thread pedal, you turn it clockwise (to the right) to loosen it.
You might wonder why there are two different thread directions. The answer lies in preventing pedal self-loosening during your rides.
Pedal rotation naturally generates forces that could loosen standard threads. By having opposite thread directions on each pedal, these forces counteract each other, reducing the risk of pedals unscrewing while you ride.
Understanding pedal thread directions has practical implications for your mountain biking adventures.
Always check the labels or markings on your pedals to identify the correct thread direction for installation and removal.
When installing or removing pedals, ensure your pedal wrench or tool is positioned correctly to avoid any damage.
