Did you know that bike pedal thread size is important? If your bike pedal threads don’t match the ones on your crank arm, then you’re going to have a tough time pedaling!

Most modern bike pedals use a 9/16 in. thread size. Older bike pedals used a 1/2 in. thread size, but this is becoming less common. There are also some pedals that use a 3/8 in. thread size, but these are much rarer.

If you’re not sure what the pedal thread size is for your bike, you can usually find it printed on the pedal itself or in the owner’s manual.

There are also some pedals that have a smaller thread size, such as the 1/4″ size. These pedals are typically used on BMX bikes or other small bicycles.

The thread size of the pedal will determine what size crank arms and pedals you can use with your bike. If you have a 9/16″ thread size on your bike, then you will need to use a 9/16″ crank arm and pedal.

If you have a 1/2″ thread size, then you will need to use a 1/2″ crank arm and pedal. It is important to make sure that you get the correct size parts for your bike, as using the wrong size can damage the threads on your bike pedals.

When shopping for new bike pedals, you will want to make sure that you get the correct size for your bike. You can typically find this information on the pedal itself, or in the owner’s manual for your bike.

If you are unsure of what size to get, you can always ask a salesperson at your local bike shop. They should be able to help you find the right size pedal for your bike.

How Can You Determine The Pedal Thread Size Of Your Bicycle?

The best way to determine the pedal thread size of your bicycle is to measure the diameter of the threaded section of the pedal axle, and then find a chart that lists common pedal thread sizes (such as this one from Park Tool). Once you know the pedal thread size, you can then find pedals that will fit that thread size.

If you don’t have a thread pitch gauge or other means of measuring the diameter of the threaded section of the pedal axle, you can also try to remove one of the pedals and take it to a local bike shop to see if they can help you identify the thread size.

Failing that, you could also try asking on a forum or online community dedicated to cycling. With enough people chiming in, chances are good that someone will be able to help you identify the thread size of your pedals.

What To Do With Mismatched Threaded Pedals And Crank Arms?

There are a few different ways to go about this, depending on the severity of the mismatched threads and whether you’re willing to make any modifications to the bike.

If the mismatched threads aren’t too severe, you may be able to get away with using a thread converter. This is a small adapter that goes between the pedal and the crank arm, and has different threading on each side to accommodate both sizes.

Moreover, If the mismatch is more significant, or you’re not comfortable using a converter, you may need to replace the pedals or the crank arms (or both) with new components that have the same threading.

This can be a bit more expensive, but it’s the most surefire way to guarantee that everything will fit together properly.

In either case, it’s always a good idea to consult with a bike mechanic or another expert before making any changes, just to be sure you’re doing everything safely and correctly.

Can I Use Pedals With A Different Thread Size?

Do All Bikes Come With Pedals That Have The Standard Pedal Thread Size?

There is no definitive answer to this question since there are a variety of bike manufacturers who all have their own specific designs and standards.

However, it is generally safe to assume that most bikes will come with pedals that have the standard 9/16″ inch pedal thread size.

There may be some exceptions for certain models or brands, so it is always best to double check before making any assumptions.

What About People Who Want To Convert Their Road Bikes Into Fixed Gear Track Bikes?

If you’re planning on converting your road bike into a fixed gear track bike, you can definitely get away with using cheaper components.

However, if you want your track bike to perform at its best, it’s worth investing in higher quality parts. This is especially true for key components like the frame, fork, wheelset, and drivetrain.

So if you’re serious about racing or just want your track bike to be as good as it can be, don’t skimp on the parts. Invest in quality components and you’ll be rewarded with a better performing bike.

Closing Thoughts

The bike pedal thread size is the same as the seatpost. This means that you can use the same tools to work on your bike pedals and seatpost.

In addition, it’s important to know the right size when purchasing new bike pedals. Make sure to measure the old ones before buying new ones!

If you’re not comfortable working on your own bike, take it to a local shop for repair or maintenance. They will be able to help you with any questions or concerns you may have about your bike pedal thread size.
