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.

Recommended Max Tire Pressure for Given Rim & Tire Volume Combo on Gravel Road Surfaces
Note: Tire pressures are intended as a starting recommendation based on the listed wheel being set up with tubeless tire.
The pressure value is calculated considering a tubeless set up, intended road surface, rider’s weight, average bike weight, inner rim width, and tire volume.
G23 = 700c x 23mm Internal Rim Width x 35 – 45mm tires
Rider’s looking for maximum versatility, speed and efficiency will gravitate towards the G23 paired with a 40mm tire. There’s a reason this is the most popular tire size in gravel right now.
G27 = 650b x 27mm Internal Rim Width x 42c – 2.25” tires
Riders on rough and loose terrain, who primarily ride dirt, often find more confidence and control from a larger volume tire. Those who prioritize traction and stable control over flat out speed will appreciate the G27.
At ENVE, product strength and durability are always top design priorities. Here’s a glimpse into the G Series toughness and the standard by which all other gravel wheels will be judged.
G SERIES IMPACT STRENGTH COMPARISON
APPLICATION SPECIFIC DESIGN & SHAPE
We demand lightweight for big elevation and long days in the saddle. We dream of floating up climbs, over obstacles and away from the pack. The G Series are the lightest tubeless rims we have ever produced.
The “bell” like shape of the G23 and G27 rim models is a lighter weight execution of our wide hookless bead and creates a rim section extremely capable of energy absorption and damping.
As carbon rims have become hookless and increasingly more durable, we have transitioned from rim failures to tire failures. Wearing a tire tread down to the casing is a thing of the past as most tires are lucky if they survive 50 miles of aggressive riding over obstacle laden terrain. While destroying an expensive tire on a weekly basis isn’t affordable, it’s a complete interruption of flow, and an utter buzzkill with a flat tire, regulated to the side of the trail.ENVE’s wide hookless bead is the result of 2 years of carbon mountain bike rim development to address this scenario. We have since adapted it into our gravel wheelsets. The result is a rim shape that features a wider leading edge of the hookless bead. This broad surface creates a more forgiving platform on which the tire can bottom out, and proves extremely effective in reducing the likelihood of “pinch” or “snake-bite” style flat.
In addition to greatly improving tire performance and reliability, the wide hookless bead design beefs up the leading edge of the rim and allows for greater impact resistance.
ENVE Wide Hookless Bead (Patent Pending) delivers:
• 60% improvement in pinch flat resistance over other hookless rims
• Ability to run lower tire pressure and improve traction and rolling resistance
• The option to run lighter weight tires if desired
• A more forgiving buffer between rim and trail
• Greater impact resistance
