# How Big Is A 700c Wheel?

**A 700c wheel is approximately 27 inches in diameter.**

A 700c wheel is typically between 28 and 32 inches in diameter. The most common 700c wheel is 29 inches in diameter. 700c wheels are often used on road bikes and hybrids.

## What Is The Diameter Of A 700c Wheel?

**The diameter of a 700c wheel is 700 millimeters.**

A 700c wheel is approximately 27 inches in diameter. The ‘c’ designation stands for ‘continental’, which is the old French measurement for wheel diameter. A 700c wheel is therefore slightly larger than a 27 inch wheel.

There are a few different ways to measure the diameter of a wheel. One is to measure from the outside of the tire to the outside of the tire. Another is to measure from the inside of the rim to the inside of the rim. The latter measurement is called the ‘effective diameter’, and is the one used most commonly when referring to wheel diameter.

To get the effective diameter of a 700c wheel, you would simply measure from the inside of one rim to the inside of the other. The result would be approximately 27 inches.

One advantage of a larger wheel is that it can roll over obstacles more easily than a smaller wheel. This is why mountain bikes often have larger wheels than road bikes. A 700c wheel can roll over small obstacles, such as potholes and cracks in the pavement, more easily than a smaller wheel.

Another advantage of a larger wheel is that it provides a smoother ride. This is because the larger circumference of the wheel results in a longer contact patch with the ground. This longer contact patch means that there are more points of contact between the wheel and the ground, which results in a smoother ride.

A 700c wheel is a good choice for someone who wants a smooth ride and the ability to roll over small obstacles.

## What Is The Circumference Of A 700c Wheel?

**The circumference of a 700c wheel is 2135.6mm.**

A common question we get at the shop is, ”

### What is the circumference of a 700c wheel?

” The short answer is that it depends on the tire size. The long answer is a bit more detailed, so let’s break it down.

To start, let’s define circumference. Circumference is the distance around the outside of a circle. So, in the case of a wheel, it’s the distance around the outside of the tire.

Now, the reason the answer to the question above is “it depends” is because different tires have different widths. And, as tire width changes, so does circumference.

To give you a real-world example, let’s say you have a road bike with 700c wheels. If you’re running 23mm-wide tires, the circumference of each tire is about 2,140mm. But, if you’re running 28mm-wide tires, the circumference of each tire is about 2,240mm. That’s a difference of about 100mm, or about 4 inches.

Now,

### Why does this matter?

Well, if you’re trying to calculate things like gear inches or development, you need to know the exact circumference of your tires. And, as you can see, that can vary quite a bit depending on the tire width.

So, the next time someone asks you what the circumference of a 700c wheel is, you can give them a more accurate answer of, “It depends on the width of your tires.”
