While it's nearly impossible to pin down just one thing that we love about Shimano, its trickle-down Dura-Ace technology is certainly near the top of our list. With every new iteration, the line between Ultegra and Dura-Ace becomes more and more blurred, which is perfectly displayed here with the new Ultegra WH-6800 Clincher Wheelset. New to this Ultegra generation, the WH-6800 features Shimano's Digital Adjustment System. Previously only available to Dura-Ace, this system essentially reduces axial force on the bearings, while also increasing the range of adjustment. How does it work? Well, as a result of the standard double-lock system, the quick-release axle naturally imposes a compression force on the axle bearings. So, Shimano abandoned this system in favor placing an internal ratcheting ring under an end cap. Accordingly, this axle compression is dispersed, leaving you with a nearly unaffected bearing-load. This means that the bearings will spin more smoothly and have an increase in durability. Additionally, Shimano has made this system simple to adjust. All that's needed is a 5mm Allen wrench to remove the end cap, and then you gain access to spin the ratcheting ring until any bearing play disappears. Also new for this year, the hubs have been widened, and the rims feature an offset design. This reduces the severity of the spoke angle on the drive-side, and accordingly, it increases the lateral rigidity while also creating a greater uniformity of tension at every point of the spoke. For even further efficiency, the 6800 wheelset uses ultra-stiff, oversized A7075 alloy axles, and a quick-engaging freehub body. Every wheel is 100% hand-built and features Shimano's own high-grade aluminum alloy rims. The front wheel has been built with 16 straight-pull, radial laced spokes, while the rear features 20 straight-pull, two-cross spokes. Additionally, the new freehub body is 10-/11-speed compatible, and the wheels are also tubeless compatible. The Shimano Ulteg...
