What Size Wrench for Bike Pedals

When it comes to wrenches, size does matter. But what size wrench do you need for bike pedals? That all depends on the type of bike pedal you have.

There are three main types of bike pedals: platform, clipless, and toe clip. Each type of pedal has a different sized wrench. Platform pedals use a 9/16 wrench, clipless pedals use a 1/2 inch wrench, and toe clip pedals use a 15 mm wrench.

So before you go out and buy a new wrench, make sure you know which type of pedal you have!

If you’re a cyclist, chances are you’ve had to ask yourself at some point, “What size wrench for bike pedals?” It’s an important question, because the answer can mean the difference between an enjoyable ride and a frustrating one. There are a few factors to consider when choosing the right size wrench for your bike pedals.

First, think about the type of pedal you have. There are two main types of pedals – platform pedals and clipless pedals. Platform pedals are the most common type, and they usually require a 15mm wrench.

Clipless pedals, on the other hand, typically require either a 6mm or 8mm Allen key. Next, consider the size of your bike’s crank arms. Most bikes have either standard or mid-sized crank arms, which means that a 15mm or 17mm wrench will usually do the trick.

However, if you have larger crank arms (usually found on mountain bikes), you may need a 20mm wrench. Finally, think about what kind of riding you’ll be doing. If you’re planning on doing any serious off-road riding, it’s always best to err on the side of caution and choose a larger wrench size.

That way, you won’t have to worry about stripping your pedal threads if you hit something unexpectedly while out on the trail. So there you have it – everything you need to know about choosing the right size wrench for your bike pedals! Just keep these simple tips in mind next time you go to make a change to your pedal setup and you’ll be good to go!

What Tools Do I Need to Change Bike Pedals?

In order to change bike pedals, you will need a few tools. First, you will need a pedal wrench or an allen key. Second, you will need a hammer.

Finally, you may need a crank puller, although this is not always necessary. To begin, loosen the bolts that hold the pedals in place using the pedal wrench or allen key. You may need to use the hammer to lightly tap the pedals if they are stuck.

Once the bolts are loose, remove the old pedals and install the new ones. Be sure to tighten the bolts securely so that the pedals do not come loose while riding. If your bike has a chain guard, you may need to remove it in order to access the Pedal Threads.

To do this, simply unscrew the retaining bolts and carefully remove the chain guard. That’s all there is to it! With these simple tools and instructions, changing bike pedals is easy and only takes a few minutes.

Can You Use a Regular Wrench to Remove Bike Pedals?

There are a few different types of wrenches that can be used to remove bike pedals, but a regular wrench is not one of them. The most common type of wrench used to remove bike pedals is called a pedal wrench. This type of wrench has a long, thin handle and a slightly offset head that fits perfectly over the flats on the back of most pedals.

Another type of wrench that can be used is an allen key or hex key. These keys are usually L-shaped and have a hexagonal (6-sided) shaft that fits into the corresponding holes in the back of the pedal. Once the allen key is inserted, you simply turn it counterclockwise to loosen and remove the pedal.

Are There Different Size Pedal Wrenches?

There are different size pedal wrenches, but they are all designed to work with pedals that have 9/16-inch threads. The most common sizes are 15mm, 16mm, and 17mm. The 15mm wrench is the smallest and is typically used for mountain biking pedals.

The 16mm wrench is a bit bigger and is typically used for road biking pedals. The 17mm wrench is the largest and is typically used for BMX pedals.

Do I Need a Special Wrench to Change Bike Pedals?

No, you do not need a special wrench to change bike pedals. A regular wrench will work just fine.

Bicycle Pedal Removal and Installation

Bike Pedal Hex Wrench

If you enjoy cycling, then you know how important it is to have the right tools with you when you head out on a ride. A bike pedal hex wrench is one of those essential tools. This type of wrench is designed specifically for use on bicycle pedals.

It is a small, lightweight tool that can easily be carried in a jersey pocket or saddlebag. The hex wrench is used to loosen and tighten the bolts that hold the pedals onto the crank arms. Most pedals have two bolts – one on each side.

The bolts are usually tightened to around 20 Newton meters (Nm). To remove the pedals, you will need to first loosen the left-side bolt using the hex wrench. Then, holding onto the pedal with your other hand, unscrew the right-side bolt until it comes free.

To install new pedals or tighten loose ones, simply follow these steps in reverse order. A bike pedal hex wrench is an essential tool for any cyclist – whether you’re a casual rider or a hardcore racer. Be sure to keep one in your kit so that you’re always prepared for anything!
