Circumference Of A 700c Bicycle Wheel
Riding a bicycle is a fun and efficient way to get some exercise, go sightseeing, or run errands. However, if you're a serious cyclist, you need to know everything about your bike, including the circumference of your bicycle wheel. In this article, we'll discuss what a 700c bicycle wheel is and how to calculate its circumference.
What Is A 700c Bicycle Wheel?
A 700c bicycle wheel is a standard size used on many road bikes and some hybrid bikes. The '700c' refers to the wheel's diameter, which is approximately 700mm. This measurement is taken from the outside of the tire, so it includes the tire's height as well.
How To Calculate The Circumference Of A 700c Bicycle Wheel
The circumference of a 700c bicycle wheel can be calculated using a simple formula: C = πd, where C is the circumference and d is the diameter of the wheel. To find the diameter of the wheel, you need to measure the distance across the rim of the wheel, passing through the center of the hub. You can use a tape measure or a ruler to do this.
Once you have the diameter, you can plug it into the formula to find the circumference. The value of π is approximately 3.14, so you can multiply the diameter by 3.14 to get the circumference in millimeters.
Why Knowing The Circumference Of Your Bicycle Wheel Is Important
There are several reasons why knowing the circumference of your bicycle wheel is important. Firstly, it can help you to choose the right size of inner tube for your bike. Inner tubes are sized according to the circumference of the wheel, so if you have the wrong size, it can cause problems with your bike's handling and performance.
Secondly, knowing the circumference of your wheel can be helpful if you use a bike computer to track your speed and distance. Many bike computers use a sensor that attaches to the wheel and measures how many times it rotates per minute. By calculating the circumference of the wheel, you can enter this information into the bike computer and get an accurate reading of your speed and distance.
Factors That Affect The Circumference Of A Bicycle Wheel
The circumference of a bicycle wheel can vary depending on several factors. Firstly, the width of the tire can affect the circumference. A wider tire will have a larger circumference than a narrower tire of the same diameter. Therefore, if you change the width of your tire, you will need to recalculate the circumference.
Secondly, the air pressure in the tire can affect the circumference. A fully inflated tire will have a larger circumference than a tire that is underinflated. Therefore, it's important to check your tire pressure regularly and adjust it as needed.
In Conclusion
Knowing the circumference of your 700c bicycle wheel is important for several reasons, including choosing the right size of inner tube and getting an accurate reading of your speed and distance. To calculate the circumference, use the formula C = πd, where C is the circumference and d is the diameter of the wheel. Remember that factors such as tire width and air pressure can affect the circumference, so it's important to check these regularly.
