ENVE - G SES 4.5 WHEELS

G SES is where aerodynamics meet the realities of modern gravel. As gravel racing has evolved, the demands on equipment have changed with it. Higher speeds now require larger-volume tyres – not only for comfort and handling, but to prevent flats from hidden rocks and ruts in the pace line. Pair those speeds with today’s wide tires, and a huge aerodynamic opportunity opens up. The G SES 4.5 and 4.5 PRO balance all performance attributes to deliver a more versatile performance solution for gravel riders and racers who place value in weight savings and nimble handling over all out aerodynamic efficiency, while delivering top honours in aerodynamics when compared to gravel aero wheels of greater or equal depth (with G SES 6.7 the sole exception)

• New rim laminate using higher modulus, lower areal weight carbon fiber
• 30 mm inner-rim width maintain clean airflow at the tyre’s leading edge, smoothing the transition across the rim sidewall, yielding significant aerodynamic savings at the modern tyre sizes between 44 and 52mm - sizes that today’s gravel riders actually use.
• Rim Depth Front/Rear: 60/67
• Innerdrive Premium Hub
• ENVE Premium stainless Bearings
• Lightweight rim graphics
• Wheelset weight: 1565 grams (including valves and tape)

OFF-ROAD CARBON EXPERTISE

ENVE’s expertise in making rims that have the impact strength to endure the most demanding off-road terrain goes back nearly two decades. The needs of an off-road tyre are different than on road, which requires unique test protocols and design elements. One such element borrowed from our line of mountain bike wheels is the Wide Hookless Bead technology that reduces pinch flats by creating a wider, blunt leading edge that dissipates impact energy.

AERODYNAMIC PERFORMANCE

We had a lot of questions around gravel racing and aerodynamics. A few years ago, we put a plan in place to answer those questions. We wanted to know how aero we could make a gravel wheel/tyre system by optimizing the rim shape to modern-high volume gravel tyres. The G SES 4.5 builds off the prolific success of the SES 4.5’s design by delivering superior handling dynamics, versatility, and weight savings, with aerodynamics that are unmatched when compared to gravel aero wheels of equal or greater depth (with the exception of the G SES 6.7).

INNERDRIVE GOES PRO

The ENVE INNERDRIVE™ Straight Pull hub uses a 100% ENVE drive mechanism. Oversized steel ratchets are positioned inboard and over the bearings, reducing stress on the axle and bearings while ensuring positive and reliable engagement. Key benefits of the INNERDRIVE™ Premium hub include:

• Weight Savings: The new ENVE INNERDRIVE™ Premium straight pull hub offering delivers 60 grams of weight savings over ENVE’s previous generation hub offering.
• Four Engagement Options: Interchangeable ratchets allow riders to tune their rides for their personal performance needs. Whether it be maximizing efficiency, response, or reliability, we have a solution. Ratchet options include: 40 tooth, 60t, 80t and 100t. Stock hubs are configured with a 60t ratchet.
• Consistent Spoke Lengths: The all-new straight-pull hubshell allows for the use of a single spoke length for any given rim diameter, creating an easy user experience for service and maintenance.
• Anti-twist Spoke Hole: To further improve the quality of the wheel build, spoke tension consistency, and to prevent spoke damage during wheel build, an anti-twist feature has been included to prevent the spoke from twisting during wheel build or while riding.
• Silent Spoke Crossings: The straight-pull hubshell puts space between each spoke, ensuring that your ENVE wheelset cannot experience spoke creak.
• Premium stainless steel bearings for low-drag and longevity.
