ENVE - SES 4.5 ON CHRIS KING HUBS - WHEELSET

Every ENVE SES wheelset is hand built in Wide Open's specialist workshop by a master 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 you’re 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 ENVE’s 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.

R45 Centerlock™ hubs pair a lightweight hub body with King's legendary, made-in-house bearings. They give you 45-points of simultaneous engagement, and that means more of your power gets to the ground and your traction is better. These hubs just roll better, last longer, and looks way more handsome than anything else out there. The stiffness of their one-piece axle translates to laser-precise bike handling.

Thery roll with King's legendary angry-bee sound, and you can choose from a bunch of sharp hub colors, including basic black. Please contact us to discuss options with coloured hubs.

REAL-WORLD FAST

ENVE’s 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 competitor’s deeper wheels, while also being lighter, and more confidence inspiring in gusting crosswinds, the SES 4.5 is the ENVE house favourite for a reason. If you’re a speedfreak looking for the perfect race wheelset, look no further.

TUBELESS OPTIMIZED

Tubeless represents the pinnacle of road wheel 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 rim’s 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.

CHRIS KING R45D HUBS

King hubs are manufactured entirely in-house in the USA, and are the first choice for riders who prize craftsmanship, performance, and long-term reliability and serviceability above all else. Our bearings, both steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously to ensure perfect matching. The quality and speed of our bearings is what you will feel (and hear) on every ride.

As Chris King bearing tracks burnish they actually get faster. A little bit of regular love (and these hubs can be completely stripped down and serviced) will keep your hubs rolling for years upon years of demanding use. These hubs look incredible and get better and better the longer you own them - wear them in, not out.
