ENVE G27 Wheel

The 27mm internal width is optimized for high-volume gravel tires, typically ranging from 40mm to 50mm or wider. This width provides a stable, square tire profile that enhances cornering support and allows you to run lower pressures without the tire squirming.

While the G27 features a hookless rim design specifically optimized for tubeless setups, it is compatible with tubeless-ready clincher tires. However, you must use a tubeless-compatible tire and sealant to ensure a safe and secure bead seat.

The hookless bead profile is wider and more rounded than traditional hooked rims, which creates a larger surface area for the tire to rest on during an impact. This design significantly reduces the likelihood of the tire casing being pinched against the rim edge, allowing you to ride lower pressures with more confidence on rocky terrain.

Yes, the Micro Spline freehub body is specifically designed for Shimano 12-speed mountain bike cassettes. If you are running a different drivetrain system, such as SRAM XDR or a standard Shimano HG setup, you will need to swap the freehub body to match your cassette.

The 650b diameter is chosen to offer increased maneuverability and clearance for wider, high-volume tires on frames that might otherwise struggle with 700c wheels. It is an excellent choice for technical singletrack, bikepacking, or smaller frame sizes where handling agility is a priority.

The straight-pull design eliminates the J-bend, which is a common failure point in traditional spokes, making the wheelset inherently more durable. While they require less frequent truing, you should still check spoke tension periodically, especially after the initial break-in period of your first few long rides.
