BIG TIRES FOR BIG SMILES
Those seeking the thrill of drop-bar riding over technical terrain that is typically frequented by mountain bikes will benefit from the air volume, durability, and anti-flat performance benefits provided by the G27. If your path leads you to rough roads, single tracks, and multi-day bike packing adventures – the G27 is for you.

The G27 is the ultimate gravel component, capable of transforming any drop bar bike into an off-road capable rig. When 650B wheels are paired with larger volume tires, the actual diameter of the outside of the tire is close to a 700c wheel with a smaller tire. This means frame geometry stays consistent between wheel sizes, but the 650B wheel adds with more tire and therefore lower tire pressures. This makes a drop-bar 700c bike more confidence-inspiring over rough terrain.

THE WIDEST (AND LIGHTEST) GRAVEL WHEEL
The G27 is the widest, and also the lightest, road/gravel wheel we make. At 320g per rim, built wheelsets can be as low as 1257 grams. Paired with a generous 27mm width, these lightweights can be paired with wider tires to create a wheel system that’s equal or lighter in weight to other wheels, while being stronger, quicker and more capable.

GET LOW
Designed to be run with tires between 42c and 2.25”, in pressures as low as 20 PSI, the G27 was made to run low. Low pressures means fewer flats, more control, and surprising to some, lower rolling resistance.

ANTI-FLAT TECHNOLOGY
ENVE’s Wide Hookless Bead technology makes the G27 extremely resistant to pinch flats. When the tire is bottomed out against the rim in a hard impact, the force is spread over a wider area, decreasing the likelihood of a flat. This contributes to the G27’s prowess as an off road weapon.
