The fire-road descent is where we felt the G27’s unique design come into play the most… they gobbled up the roots and spit out the rocks.– road bike action
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.
ENVE’s patented Molded Spoke Hole Technology offers a variety of benefits that ultimately result in a more durable and reliable carbon fiber rim and wheel. Visit Why ENVE for more details.
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
NEEDS IMAGE FROM TECHNOLOGIES ON G23 PAGE
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 above scenario. 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
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.
Gravel riding shouldn’t be confined to one wheel size. For maximum control, it’s got to be 650b.
WITH SMALL WHEELS AND BIG TIRES, THE G27 PROVIDES THE MOST DESCENDING CAPABILITY ON A DROP BAR BIKE.
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.
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.
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 by X percent. This contributes to the G27’s prowess as an off road weapon.
