The AMERICAN CLASSIC Grus Gravel Bike Tire is a top-tier replacement tire designed specifically for gravel bicycles. With a size of 700 x 40c, this tire stands out for its incredible performance across various mixed terrain conditions. Whether you’re racing or enjoying a leisurely ride, the Grus tire ensures a reliable and efficient experience.

One of the standout features of the Grus tire is its tightly spaced central tread, which provides exceptional speed on lighter terrains. This design is complemented by hooked shoulder knobs that enhance cornering control on rough surfaces, giving riders the confidence they need when navigating challenging paths. Additionally, open transition knobs have been incorporated to prevent build-up, ensuring consistent traction.

The Grus tire is equipped with a Tubeless Ready 120 TPI casing, which offers a supple ride while maintaining durability. This construction allows for a combination of speed and comfort, particularly when paired with tubeless-specific sealants. Moreover, the inclusion of Stage 5S Armor technology enhances the tire’s cut and abrasion resistance, making it an ideal choice for gravel racing enthusiasts.

Another significant aspect is the Rubberforce G compound, a specially-tuned rubber engineered to deliver dependable grip on mixed terrain. This feature is essential for daily adventures, allowing riders to tackle various surfaces with ease. The wide range of conditions the Grus tire can handle makes it a versatile option for cyclists seeking performance and reliability.

When it comes to tire widths, the Grus tire meets the current global standards set by E.T.R.T.O.. Specifically, the 40mm tires are designed for rims with 23mm internal widths, while the 45mm tires cater to rims with 25mm internal widths. It’s crucial to note that using narrower or wider rims may alter the overall width of the tire, affecting performance.

Furthermore, the fitting of the American Classic tires adheres to the dimensions established by E.T.R.T.O. and ISO 5775. These specifications enhance rider safety by ensuring a functional pairing of tires and rims that meet the same standards. This results in tighter tolerances, leading to a snug fit on rims, which may necessitate some users to adjust their installation methods compared to previous standards.

In conclusion, the AMERICAN CLASSIC Grus Gravel Bike Tire is an exceptional choice for cyclists who demand high performance and versatility from their tires. Its thoughtful design and advanced materials ensure that you can conquer any gravel path with confidence. Whether for racing or casual rides, the Grus tire will elevate your cycling experience.
