Enve G27 650B Carbon Gravel Rim


With the rise of gravel and mixed surface riding, Enve sought to fill a gap in their rim lineup that would offer both the toughness and flat resistance of their mountain rims while maintaining the light weights and high efficiency of their road rims. Using the insight gained in building some of the world’s best road and mountain rims, Enve created the G27, their definition of a true gravel rim.  As the second entry into Enve's new lineup of gravel rims, the G27 is billed as the "little big brother" to their G23 rim.  This title fits perfectly, as while the rim is a smaller diameter and comes in lighter than the G23 (650b/27.5/320 grams vs. 700c/330 grams), it has wider internal and external widths (35.5mm external/27mm internal vs. 31.5mm external/23mm internal).  The G27 is designed for disc brakes and use with the higher volume tires that riders demand for rougher and looser terrain.  

At 320 grams, Enve’s G27 opens up a new world of riding possibilities, allowing set ups with more range than xc/trail bikes while being much more capable off-road than traditional road bikes. With its generous 27mm internal width, the G27 is designed to be paired with gravel and road plus treads between 42mm-60mm and 27.5 XC mountain treads from 1.9"-2.25". While this range of tire widths provide plenty of control and traction, they do not offer much as far as pinch-flat protection. To greatly reduce the likelihood of “pinch” or “snake-bike” style flats, the G27s feature Enve’s Wide Hookless Bead technology developed for its mountain rims. This technology makes use of a wider leading edge of the hookless bead, a broad surface that creates a more forgiving platform for tire bottom-outs. The result is the ability to confidently ride the tire pressures you want, without limitations. With the molded bead-lock, the tubeless G Series ensures the tires will remain secure and sealed over the roughest terrain.

The G27 was created for riders looking for the challenge of drop-bar riding over technical terrain that is traditionally considered mountain bike territory.  The higher air volume, durability and anti-flat performance of the G27 greatly benefit riders who are drawn to rough roads, single tracks, and multi-day bike packing adventures.  Designed to tackle terrain littered with contradicting challenges, these rims meet the performance and ride quality demands of the most serious mixed-surface cyclists, Enve’s G27 is a go-to rim for discovering new terrain and conquering new challenges.
