Every ENVE SES wheelset is hand built in Wide Open’s specialist workshop by an expert wheelbuilder. Our expertise and precise control over the build process ensure that every wheel we produce delivers the ultimate in performance and reliability.

The ENVE house favorite for its outright speed and confidence-inspiring ride, the SES 4.5 has been re-engineered to reduce weight, increase aero efficiency and further expand its capabilities when the going gets fast. Whether youre pinning on the number for race day or seeking the fastest road wheelset across undulating terrain, the SES 4.5 is in the sweet spot for speed.

With an internal rim width of 25mm, confident handling results, making the SES 4.5 a game-changer on technical courses with imperfect pavement. Like the rest of the SES wheel line, the SES 4.5 has been optimized for road tubeless performance and features a hookless bead design that allows for the precise rim dimensions required to achieve the best tubeless performance. To further improve tubeless tyre and rim reliability, this aerodynamic carbon fiber wheelset features ENVEs patent pending Wide Hookless Bead, a design element at the leading edge of the rim that provides a more forgiving surface, that when impacted, will reduce the likelihood of pinch-flatting a tubeless tyre.

The SES 4.5 is now built on our groundbreaking newINNERDRIVE hub, pushing into a new level of World Tour proven performance.

REAL-WORLD FAST

ENVEs aero wheel development program is driven by our Real-World Fast mantra. This means that each wheel is developed under consideration of airflow efficiency, crosswind stability, handling, weight, tire integration, and much more. The result is a refined collection of wheels that are purpose built to be best-in-class and provide the maximum speed and efficiency benefit available for their intended discipline application.

Over time, the SES 4.5 has redefined the bar by which all other aero wheels are judged. Faster than nearly all our competitors deeper wheels, while also being lighter, and more confidence inspiring in gusting crosswinds, the SES 4.5 is the ENVE house favorite for a reason. If youre a speedfreak looking for the perfect race wheelset, look no further.

THE SES DIFFERENCE

Theres a simple reason why SES wheels consistently score best in test in nearly any third-party aero test. Were committed to sweating the small stuff and chasing the marginal gains that others will not.

• In-frame development and ride testing have taught us that unique rim shapes and constructions between the front and back wheels optimize efficiency and the ride experience. Front wheels are designed to maximize crosswind stability. A rider’s stability on the bike, especially in time trial and triathlon, is critical for aero efficiency and overall performance.Rear wheels are designed to recapture air flow as it passes from the front of the bike to the back, which maximizes drag reduction.
• Aerodynamically optimized around modern high-volume tubeless tires.The all-new SES lineup was developed around the ENVE SES 27mm tire.
• Tested at 20 mph (32 kph) and 30 mph (48 kph). Our SES promise of Real-World Fast isnt limited only to cyclings elite.
• Weighted Average Drag: All wind angles are not created equally. Anemometer data shows that most of your ride time will be spent in wind at less than 12 degrees yaw. Weighted average drag is a tool that helps a rider understand the aero efficiency of a wheelset in real-world wind and riding condition

TUBELESS OPTIMIZED

Tubeless represents the pinnacle of roadwheel and tyre performance.Like the rest of the SES wheel line, the SES 4.5 has been optimized for road tubeless and features a hookless bead design that allows for the precise rim dimensions required to achieve the best tubeless performance.

A hookless rim design allows for machined metal tooling to establish a precise and consistent bead seat diameter. The resulting precision fitment between the tubeless tyre bead and the rims bead seat ensures optimum air and tyre retention.

ENGINEERED FLAT PROTECTION – WIDE HOOKLESS BEAD

Most flat tyres are caused by one of two things: Intrusion punctures (staples, thorns, glass, etc.) or pinch-flats (potholes, railroad tracks, rocks, etc.). While there is little we can do as a rim manufacturer to prevent punctures, our patent-pending Wide Hookless Bead greatly reduces the likelihood of pinch-flatting. Wide Hookless Bead technology works by providing a blunt surface upon which to bottom out the tyre, dissipating energy across a larger surface area and preventing tyre damage. This allows you to run the correct tyre pressure without the worry of pinch-flatting.

ENVE INNERDRIVE PREMIUM ROAD HUB

Featured in all NEW SES and G Series wheels is the ENVEINNERDRIVE Straight Pull hub, an all-new, 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 ENVEs 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.
