GOT QUESTIONS? WE'VE GOT ANSWERS.

Yes, especially for performance-focused riders. Carbon rims offer lower weight, increased responsiveness, and a more refined ride feel. The result is a noticeable improvement in speed, efficiency, and overall ride quality.
Carbon allows us to build wider rims without the weight penalty associated with alloy. This means you get the benefits of increased tyre support, stability, and control while maintaining a lighter and more efficient wheel system.
Yes, wider carbon rims provide better tyre support, increased grip on loose terrain, and improved stability at speed. This leads to greater confidence and control, particularly on rough or technical gravel.
Because compliance matters more than aerodynamics on gravel. A lower profile allows the rim to absorb impacts, maintain momentum, and deliver a smoother ride. This results in better performance across real-world terrain where comfort and control are critical.
Yes, primarily due to their lower weight and improved efficiency. Carbon rims help maintain speed more effectively over rough terrain, making them faster in real-world gravel riding conditions.
Deep aero rims are designed for high-speed road riding and offer limited benefit on gravel. They tend to be less compliant, which increases bouncing, reduces comfort, and makes the bike harder to control. Low profile rims are faster and more effective for gravel terrain.
Yes, GNARLY carbon rims use a hookless design. This allows for a thicker, stronger rim edge, improving durability and impact resistance while optimising performance for tubeless systems.
Yes, when used with compatible tyres. Hookless rims are widely used in modern gravel setups and are designed specifically for tubeless systems. They offer a strong, durable rim interface when paired correctly.
Depending on the model, GNARLY carbon rims are optimised for different tyre ranges. A 26mm internal rim suits approximately 38–50mm tyres, while a 30mm internal rim is better suited to 45–60mm tyres, providing increased comfort and control on rough terrain.
Yes, upgrading to carbon rims will improve speed, control, and overall ride quality. You’ll experience smoother rolling, better handling, and increased confidence on rough gravel, making them a true performance upgrade.
