ENVE AR IN-Route Fork

The ENVE AR IN-Route fork uses a tapered 1.125/1.5-inch steerer tube and a 12x100mm thru-axle, which are standard for most modern disc-brake road bikes. However, you should verify your frame's axle-to-crown measurement and rake requirements to ensure the handling geometry remains consistent with your bike's original design.

The IN-Route system is designed to route your brake hoses and electronic wires internally through the headset and into the frame. This eliminates exposed cables at the front end, which cleans up the bike's aesthetic and provides a measurable aerodynamic advantage.

While the fork is designed for integration, it is specifically optimized for use with ENVE’s IN-Route cockpit components. Using a standard stem and handlebar may make it difficult or impossible to achieve the internal routing benefits the fork is engineered for.

This fork offers clearance for tires up to 40mm wide. This makes it a versatile choice for all-road builds where you might want to switch between fast road tires and wider, more compliant rubber for rougher surfaces.

Yes, the fork is compatible with both 160mm and 180mm flat-mount disc rotors. This gives you the flexibility to increase stopping power, which is particularly useful if you are using the fork for gravel or mixed-terrain riding.

While it is categorized as an 'all-road' fork, its lightweight carbon construction and 40mm tire clearance make it a capable option for light gravel riding and racing. If you are planning on tackling extremely technical or rocky terrain, you might prefer a dedicated gravel fork with even greater tire clearance.
