Surly

Ultra Light Fat Tube

Butyl rubber is a synthetic rubber known for its excellent air retention properties, making it ideal for bicycle inner tubes. It helps keep tires inflated for longer periods, reducing the need for frequent inflation. Additionally, butyl rubber is durable and resistant to wear and tear, ensuring a longer lifespan for your inner tubes.

A Presta valve is a type of valve used on bicycle inner tubes that is narrower and typically found on higher-end bikes. Unlike the more common Schrader valve (used in car tires), Presta valves require a special pump or adapter for inflation. They are preferred by many cyclists because they can hold higher pressures, making them ideal for performance-oriented riding.

Fat biking involves riding bicycles equipped with oversized tires, usually 3.8 inches or wider. These bikes are specifically designed to handle soft and unstable terrains like snow, sand, and mud. The wider tires provide better traction and stability, allowing riders to explore areas where traditional bikes may struggle.

"Claimed weight" refers to the weight of a product as stated by the manufacturer. For example, the Surly Ultra Light Fat Tube has a claimed weight of 10.9 ounces (310 grams). This information is crucial for cyclists who want to minimize the weight of their gear, as lighter equipment can enhance performance and make riding more enjoyable.

"Ultra Light" indicates that the Surly Ultra Light Fat Tube is designed to be lighter than similar products on the market. This means it has been engineered to reduce weight while still maintaining the necessary durability and performance for fat biking. Choosing an ultra-light inner tube can help improve your overall cycling experience by making your bike easier to handle.

The Surly Ultra Light Fat Tube combines the benefits of butyl rubber for excellent air retention and durability with a lightweight design. This means you can enjoy longer rides without worrying about frequent inflation, while also benefiting from a lighter setup that enhances your bike's performance on challenging terrains.
