Whether paved or not, no road or wind will slow your roll. The ENVE 4.5 AR Disc laced to Chris King R45D hubs, with our ultra-smooth bearings and lightweight hubshells, is an uncompromising aero design specifically built for modern road disc bikes with larger tire clearance. This is an all around performance wheelset, with an emphasis on speed.
The ENVE 4.5 AR Disc is built optimized for 30mm tires, to provide greater stability and packing a serious aerodynamic edge. These rims are tubeless ready for an even more supple ride. To keep their rims ultralight ENVE uses molded rather than drilled spoke holes, a patented design that makes their wheels lighter and stronger at the same time. ENVE 4.5 AR Disc are made in Ogden, Utah and backed by a five-year warranty.
The R45 is the culmination of over 30 years of bearing experience and more than 20 years of hub building experience. Our R45 rear hub combines a redesigned RingDrive™ system with 45 teeth for lower drag and near instant engagement, a lightweight hub body, and our legendary made-in-house bearings.
Our bearings, available in steel and ceramic, surgical grade steel races that are machined simultaneously to ensure perfectly matched inner and outer races. The quality and speed of our bearings are what sets us apart from the competition and they are what you will feel and notice on every single ride. As Chris King bearing tracks burnish they get faster with age and all our hubs and bearings are fully serviceable for years upon years of demanding use.
The patented Chris King RingDrive with 45-points of simultaneous engagement will get your power to the ground fast, provide unmatched engagement, and give you that legendary Chris King angry-bee sound.
No complaints so far, but I have only done a couple rides. These Enve 4.5 AR wheels are aero optimized for 28mm, and I have mounted them on my custom 2018 Trek Emonda slr disc. The Schwalbe Pro Ones, set up tubeless, swelled up to 33.3 mm at 60 psi. I could probably get away with a 30mm tire on the Emonda, but that's the largest tire that will fit with these super wide wheels. They handle great, accelerate about the same as my Bontrager aelous pro 3s I had on there previously, and look incredible (matte turquoise hubs). They are also fairly light for how deep they are. My local Chris King expert tech let me know that the wheels will be a bit draggy the 1st 100-200 miles, and after that they will be smooth as butter. He also told me it's a good rule of thumb, especially with ceramic bearings, to pull apart the hubs and check on them every 6 months to a year of riding. Just in case any contamination gets in there, it can be cleaned and flushed out. This is more relevant if you are gravel riding. I will probably get them checked as part of an annual tune up which I do every year anyway.
