Bicycle pedals are one of the most important components of a bike. They allow the rider to transfer their power to the bike and move forward. However, not all pedals are the same. One of the most important things to consider when buying pedals is the thread standard. In this article, we will discuss the different thread standards for bicycle pedal threads.
Standard Thread Sizes
There are two main thread standards for bicycle pedals: English and Metric. The English standard uses 9/16 inch threads while the Metric standard uses M14 threads. It's important to know which standard your bike uses before buying pedals, as you won't be able to install pedals with the wrong thread size.
Thread Pitch
The thread pitch is the distance between each thread on the pedal. The English standard uses a 20 threads per inch (TPI) pitch while the Metric standard uses a 1.25mm pitch. It's important to match the pitch of your pedals to your bike's crank arms to ensure a secure fit.
Left and Right Threads
Bicycle pedals have a different thread on each side of the pedal. The left side uses a reverse thread, meaning you need to turn it clockwise to loosen it. The right side uses a standard thread, meaning you need to turn it counterclockwise to loosen it. This is to prevent the pedals from loosening while riding.
Thread Materials
Pedal threads can be made from different materials such as steel, aluminum, or titanium. Steel is the most common material used for pedal threads as it's strong and durable. However, titanium is becoming more popular due to its lightweight and corrosion-resistant properties.
Compatibility
Not all pedals are compatible with all crank arms. Some crank arms are designed for specific pedal brands or thread standards. It's important to check the compatibility of your pedals and crank arms before purchasing them.
Installation
Installing pedals on your bike is a straightforward process. First, make sure you have the correct thread size and pitch. Then, apply some grease to the threads to prevent them from seizing. Finally, use a pedal wrench to tighten the pedals onto the crank arms.
Maintenance
Pedal threads should be checked regularly to ensure they are tight and secure. If they become loose, they can cause damage to the crank arms or the pedals themselves. Applying grease to the threads during maintenance can also help prolong the lifespan of the pedals.
Conclusion
Understanding the different thread standards for bicycle pedals is important when buying and installing pedals on your bike. Remember to check the thread size, pitch, and compatibility before purchasing pedals. Regular maintenance can also help prolong the lifespan of your pedals. With this knowledge, you'll be able to ride your bike with confidence and security.
