Choosing the Perfect Valve Length for 35mm Rim

When it comes to purchasing new bike equipment, there are a few key factors to consider in order to ensure the best performance and comfort while riding. One of these factors is the valve length for 35mm rims. While it may seem like a minor detail, choosing the perfect valve length can greatly affect the overall quality of your bike ride. In this article, we will discuss the importance of valve length for 35mm rims and provide tips on how to choose the perfect length for your bike.

Firstly, let’s define what valve length for 35mm rims actually means. The valve length refers to the length of the valve stem that is attached to your bike’s inner tube. The inner tube is what holds the air inside your bike tire, and the valve stem is what allows you to inflate and deflate the tube. For 35mm rims, the diameter of the valve hole is typically 6.5mm. This means that the valve length should be long enough to reach through the rim and allow for a secure attachment to the pump while still leaving enough clearance from the rim.

So why is the valve length so important for 35mm rims? The main reason is to ensure a tight seal between the inner tube and the rim. When the valve stem is too short, it may not be able to reach through the rim, leaving a small gap where air can escape. This can result in frequent deflation of your tires and a bumpy ride. On the other hand, if the valve stem is too long, it can bend and kink inside the rim, causing air to leak out as well. This not only affects the performance of your ride but can also be a safety hazard.

Now that we understand the importance of valve length for 35mm rims, let’s discuss how to choose the perfect length for your bike. The most important thing to consider is the depth of your rim. 35mm rims come in different depths, ranging from 18mm to 25mm. The deeper the rim, the longer your valve stem needs to be in order to reach through and attach to the pump. For example, a 18mm rim depth would require a shorter valve length compared to a 25mm rim. It’s always a good idea to measure the depth of your rim before purchasing new inner tubes to ensure a proper fit.

Another factor to consider is the type of valve. There are two types of valves commonly used for 35mm rims – Presta and Schrader. Presta valves are slender and require a smaller valve hole in the rim, while Schrader valves are thicker and require a larger valve hole. If your rim is specifically designed for Presta valves, make sure to choose a valve length that is suitable for it, and vice versa.

Apart from the rim depth and valve type, it’s important to also consider your riding style and terrain. For those who ride on rough, rocky trails, it’s recommended to choose a slightly longer valve length to allow for more clearance between the valve and the rim. This will minimize the risk of the valve getting damaged or bent. On the other hand, if you primarily ride on smooth roads, a shorter valve length may suffice.

In addition to these factors, it’s also important to regularly check and maintain your valve length for 35mm rims. Over time, the constant use and pressure on the valve can cause it to stretch and become slightly longer. This can result in a loose fit and increase the risk of air leaks. It’s a good idea to periodically replace your inner tubes and check the valve length to ensure it’s still the right fit for your rims.

In conclusion, valve length for 35mm rims may seem like a small detail, but it plays a crucial role in the performance and safety of your bike ride. Before purchasing new inner tubes, make sure to measure the rim depth, consider the type of valve and your riding style, and regularly check and maintain the valve length. By choosing the perfect valve length, you can ensure a smooth and enjoyable ride every time. Happy cycling!
