Introduction
When it comes to bicycles, one of the crucial components that often goes overlooked is the bicycle pedal. Pedals are what connect our feet to the bike, allowing us to propel forward and experience the joy of cycling. However, not all pedals are created equal, and today, we will dive into the world of bicycle pedals to understand the different types, functions, and specifically, the intricacies of reverse threaded pedals.
Understanding Bicycle Pedals
Before we delve into the realm of reverse threaded pedals, let’s first gain a basic understanding of bicycle pedals in general. There are various types of bicycle pedals available in the market, each with its unique features and advantages. Let’s explore these types and their functions in more detail.
Types of Bicycle Pedals
The most common types of bicycle pedals include platform pedals, clipless pedals, and toe-clip pedals.
Platform Pedals:
Platform pedals are the simplest and most basic type of bicycle pedals. They consist of a flat surface where you place your foot and allow for easy entry and exit. These pedals are commonly found on mountain bikes, hybrid bikes, and casual city bikes.
Clipless Pedals:
Clipless pedals, despite their name, actually involve clipping in. These pedals use a cleat system that attaches to the bottom of cycling shoes. This design ensures a more efficient transfer of power and allows for a greater connection between the cyclist and the bike. Clipless pedals are widely used by road cyclists, triathletes, and competitive riders.
Toe-Clip Pedals:
Toe-clip pedals, also known as cage pedals, are a combination of platform pedals with an added strap or cage to secure the foot. These pedals offer a more secure connection compared to platform pedals while still allowing for easy entry and exit. Toe-clip pedals are popular among commuting cyclists and touring riders.
Function of Bicycle Pedals
The primary function of bicycle pedals is to convert the rotational energy generated by the cyclist’s leg movement into forward motion. Pedals provide a platform for the rider’s foot to push down and forward, applying force to the cranks, and ultimately propelling the bicycle. Additionally, pedals play a crucial role in maintaining stability and control while riding.
Common Terminology
Before we continue, let’s familiarize ourselves with some common terminology used when referring to bicycle pedals.
Crank:
The crank is the metal arm or rod that extends from the bicycle’s frame and is attached to the pedal. The circular motion of the cranks is what drives the bicycle forward.
Spindle:
The spindle is the central component of the pedal that connects the pedal body to the crank arm. It allows the pedal to rotate smoothly around the crank.
Axle:
While the term axle is sometimes used interchangeably with the spindle, it can also refer to the entire pedal, including the spindle and associated hardware.
Thread Direction
Now that we have a grasp of the basic types of pedals and their functions, it’s essential to understand the concept of thread direction. Thread direction refers to the direction of the screw-like threading on the pedal spindle that determines how the pedals are installed or removed.
Pedals have either a right-hand (standard) thread or a left-hand (reverse) thread. In a right-hand threaded pedal, the left pedal is installed by rotating it counterclockwise (to the left) and the right pedal by rotating it clockwise (to the right). Reverse threaded pedals, on the other hand, have the opposite threading, with the left pedal requiring clockwise rotation and the right pedal requiring counterclockwise rotation.
Right-Hand (Standard) Threaded Pedals
Now that we understand the concept of thread direction let’s take a closer look at right-hand threaded pedals, which are the standard in most bicycles.
Overview
Right-handed threaded pedals are the most common type of pedal found on bicycles. As mentioned earlier, these pedals are installed by rotating the left pedal counterclockwise (to the left) and the right pedal clockwise (to the right). This standard threading ensures that the pedals naturally tighten as you pedal, preventing them from loosening unintentionally.
Usage
Right-handed threaded pedals can be used on any side of the bicycle. This means that the left pedal can be used on the left side of the bike, and the right pedal can be used on the right side. However, it is important to note that using the appropriate pedal on the correct side is essential for proper installation and optimum performance.
Thread Direction
The threading on right-handed threaded pedals is right-hand thread, meaning it follows the traditional clockwise-tightening pattern. This right-hand thread direction ensures that the pedal remains securely attached to the crank arm while cycling.
Installation and Removal
Installing and removing right-handed threaded pedals is relatively straightforward. To install a right pedal, screw it in clockwise (to the right) onto the crank arm. Similarly, to remove a right pedal, rotate it counterclockwise (to the left) until it is loose enough to be unscrewed by hand or with tools.
Left-Hand (Reverse) Threaded Pedals
Let’s now turn our attention to left-hand threaded pedals, also known as reverse threaded pedals.
Overview
Left-hand threaded pedals are less common than their right-hand counterparts but are still found on certain bicycles. These pedals feature the opposite threading, with the left pedal requiring clockwise rotation and the right pedal requiring counterclockwise rotation for installation and removal. The reverse threading helps eliminate the chances of the pedals loosening when subjected to the rotational forces of pedaling.
Usage
Similar to right-handed threaded pedals, left-hand threaded pedals can also be used on any side of the bicycle. However, using the correct pedal on the appropriate side is vital for proper installation and optimal performance.
Thread Direction
Left-hand threaded pedals have left-hand thread direction, which means they follow a counterclockwise-tightening pattern. This reverse threading prevents the left pedal from loosening during pedaling, ensuring a secure attachment to the crank arm.
Installation and Removal
Installing and removing left-hand threaded pedals will differ from the process used for right-handed threaded pedals. To install a left pedal, rotate it clockwise (to the right) onto the crank arm. When removing a left pedal, rotate it counterclockwise (to the left) until it is loosened enough to unscrew by hand or with suitable tools.

Identifying Reverse Threaded Pedals
Now that we have explored the basics of reverse threaded pedals, it’s important to know how to identify them correctly.
Visual Inspection
One way to identify reverse threaded pedals is through a visual inspection. While this method may not be foolproof, it can often provide some hints. Look for any distinguishing marks or uneven threading on the pedal spindle that might indicate reverse threading.
Manufacturer’s Markings
Pedals may sometimes have markings or symbols etched or printed on them to indicate reverse threading. Look for arrows or letters such as “L” or “R” to determine which pedal goes on which side of the bicycle.
Owner’s Manual
If you have access to the owner’s manual of your bicycle or the specific pedal model being used, it can be a great resource for identifying reverse threaded pedals. The manual should provide detailed instructions on pedal installation and removal, including any specific information about reverse threaded pedals.
