ENVE Composites G23

These rims are specifically optimized for 40mm gravel tires. While you can run a range of widths, the 23mm internal width provides the ideal profile and support for tires in that 40mm sweet spot.

The G23 features a hookless bead design, which is engineered specifically for tubeless setups. While you can technically use a tube in an emergency, these rims are designed to be run tubeless for the best performance and pinch-flat protection.

The hookless bead, combined with ENVE’s molded bead-lock system, creates a very secure interface between the tire and the rim. This design significantly improves tire retention at lower pressures and helps prevent the tire from burping during aggressive cornering or rough terrain.

While the G23 is purpose-built for gravel and mixed-surface riding, its lightweight carbon construction makes it a capable climber on any surface. However, if you are strictly riding pavement, you might prefer a rim with a deeper profile for better aerodynamics.

The 25mm depth is chosen to balance weight savings with compliance. It keeps the wheelset incredibly light for rapid acceleration while offering enough vertical compliance to absorb chatter and vibration on rough gravel roads.

Yes, because of the specific bead-lock design, you should use high-quality tubeless tape that is compatible with hookless rims. Ensuring a proper seal is key to taking full advantage of the rim's pinch-flat protection.
