ENVE G27 650B Carbon Clincher ENVE Alloy Disc CL 12/142 Wheelset

The G27 is the G23’s little big brother. Smaller in diameter and lighter in weight, the G27 is designed for disc brakes and higher volume tires demanded by many riders on rougher and looser terrain. At 320 grams, our lightest tubeless rim is 27mm wide and designed for tires marked 27.5 or 650B. Armed against pinch flats with the patent pending Wide Hookless Bead, the G27 is at home off-road and capable on tamer stretches of singletrack.  

Those seeking the challenge of drop-bar riding over more technical terrain that is typically frequented by mountain bikes will benefit from the additional 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 may be for you.
There is a place between road and mountain open to discovery. Beyond the range of your trail bike or the capabilities of your road bike. Terrain littered with contradicting challenges and demanding requirements are at odds with the bikes and products available today. We built the new G27 to thrive in this new environment because insight gained through building the world’s best road and mountain bike rims told us that the perfect combination did not exist in our stable, or in our opinion, anywhere at all. The higher volume and lower pressures would demand MTB toughness and flat resistance, while big days and long miles would require the lightweight and efficiency of a road machine. Above all, the combination of rough and rigid would require a wheel with the ride quality to make those long miles enjoyable and multi-day trek possible.
We want people to have as much fun riding gravel as we do and for that reason we’ve targeted rim geometries that favor the tire treads and volumes that have proven to be the most fun. With an inner rim width of 27mm the G27, is designed to be paired with 650B gravel and road plus treads from 42mm-60mm and 27.5 XC mountain treads from 1.9”-2.25”. These light casing, supple tires provide ample control and traction, for most gravel riding endeavors, but they do not offer much by way of pinch-flat protection. Despite ‘min PSI’ markings to the contrary, many riders are experimenting with pressure setting in the 20s. The forward-looking G27 is ahead of the trend using our Wide Hookless Bead anti-flat technology, which provides a larger, more forgiving surface during bottom outs, protecting the tire from the dreaded pinch-flat. This technology means you can ride the tire pressures you want, confidently, without limitations. The G Series are intended for tubeless applications and features a molded bead-lock to ensure that your tires will remain secure and sealed to the rim over even the roughest terrain.
