ENVE Composites G27 Wheel

The G27 is optimized for high-volume gravel tires ranging from 42c up to 2.25 inches. This width provides a stable platform for wider rubber, allowing you to run lower pressures for better traction on loose surfaces.

The G27 features a hookless bead design, which is specifically engineered for a tubeless setup. While you can technically use a tube in an emergency, these rims are designed to perform best as a tubeless system to take full advantage of the puncture resistance and comfort benefits.

The wider, hookless rim profile creates a larger surface area where the tire bead meets the rim. This design significantly reduces the likelihood of 'pinch flats'—where the tire is compressed against the rim edge—by up to 60% compared to traditional hooked rims.

The G27 is built with a 12x142 mm axle standard, which is the industry standard for modern disc-brake gravel bikes. Please double-check your frame's rear spacing to ensure it matches this configuration.

The Innerdrive system uses oversized steel ratchets rather than traditional pawls. This provides more reliable engagement and puts less stress on the bearings, resulting in a more durable hub that holds up better under the torque of gravel riding and bikepacking.

They are definitely capable of handling rougher terrain. The combination of the 27mm internal width and the durable carbon construction makes them well-suited for trail exploration and unpredictable surfaces where you need extra control and impact resistance.
