2023 Enve G23 7C Carbon Fiber Wheelset

What It IS

The G23 is the definition of a true gravel wheelset. At 330 grams, ENVE’s lightest 700c tubeless rim accelerates quickly and ascends with ease. Armed against pinch flats with the patent pending Wide Hookless Bead, the G23 is tough and relentless on road, path or trail. The G23 is a 700c tubeless carbon clincher wheelset, with a generous 23mm internal width, specifically conceived to meet the performance and ride quality demands of serious mixed surface cyclists.

Who It's For

Created for those seeking to discover new experiences, new terrain, and new challenges. Built to reflect the versatility of today’s gravel and mixed surface riders, these wheels will excite ambitious, daring and indomitable riders everywhere. If your path leads to classics like Dirty Kanza, Landrun, Crusher in the Tushar, or a new wave of events like Grinduro, or Lost and Found, the G23 is your wheel.

Why We Made It

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 G23 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 treks possible.

Full Details

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 23mm the G23, is designed to be paired with gravel treads between 35mm and 45mm. While 35mm-45mm tires provide ample control and traction, for most gravel riding endeavors, they do not offer much by way of pinch-flat protection. Despite ‘minimum PSI’ markings to the contrary, many riders are experimenting with pressure setting in the 20s. The forward-looking G23 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.

Tire Compatibility

SES G Series wheelsets feature a straight sidewall/hookless bead design to ensure best in class tubeless tire performance and are qualified for use with “Tubeless, Tubeless Ready (TLR)” tires, with a labeled width of 28c or greater ONLY. One may safely run inner-tubes as long as the tire itself is of a tubeless or tubeless ready construction.

Please note that the internal rim width of the G23 is 23mm and intended for use with tubeless ready tires between 32-45mm with 40mm tires being the primary focus of the design. The G27 features a 27mm internal width that is intended for pairing with tires between 42-60mm with 55mm/2.0” tires being the target tire width for this rim.

Due to the straight sidewall/hookless design of this rim and inherent high volume design, it is important to understand that not all tires are created equal and for that reason one should pay special attention to the pressure ratings of both the tire and the rim.

G23 - Max Pressure For a 32mm Tire = 60psi/4.1bar

G27 - Max Pressure For a 42mm Tire= 40psi/2.75bar

IN THE CASE THAT TIRE AND RIM MAX PRESSURES ARE DIFFERENT. THE LOWER OF THE TWO PRESSURES BECOMES THE DEFAULT MAX PRESSURE FOR THE SYSTEM.

THE MAX PRESSURE RATING FOR EACH RIM WILL DECREASE AS YOUR TIRE VOLUME/SIZE INCREASES. REFER TO RECOMMENDED TIRE PRESSURE CHART.

ENVE Tip: Trust our tire pressure recommendation chart. The maximum tire pressure ratings on tires are not recommended operating pressures. Running the max pressure will not make you faster, rather, it will actually increase rolling resistance (making you slower) and discomfort (making you slower), jeopardizing the ride experience.

Technology

• HIGH 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.

• MOUNTAIN STRONG ROAD FAST
  

  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

  • Tested to ENVE mountain impact standard
  • Rated for unsuspended to lightly suspended bikes under the assumptions that technical terrain and obstacles are negotiated at lower speeds than mountain bike
  • Mountain strong, but not ENVE mountain strong.
  • While these wheels are stronger than many mountain bike wheels in the market, they rate just below the elevated impact strength of our new M Series

  

• 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.

• WIDE HOOKLESS BEAD

  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
