Not content with leaving it's Black Label line the same for its third birthday, Reynolds released a brand new version of the 27. 5 Enduro Black Label Wheelset this year, and although it still shares some features with the versions we're all familiar with, we're looking at an all new beast. The top of the line hoops manage to be stronger and stiffer than their predecessors, while promising a suppler, more responsive ride using a new carbon rim profile and an exclusive version of Industry Nine's legendary hubs, readying the wheels for aggressive trail and hard charging enduro riding all over the mountain. If you looked closely at the Enduro Black Label rims, you wouldn't be imagining things if you noticed that they don't look the same all the way around. This is intentional our Utah based neighbors over at Reynolds carefully shaped the carbon fiber rims asymmetrically this year to strengthen the wheels on the drive side where it's needed most, avoiding adding unnecessary extra weight to the non drive side. With this construction, Reynolds ensures that the entire wheelset gains strength and rigidity, without a total compromise of ride quality. As you blast through a teeth chattering stretch of rock gardens, the wheels will roll over whatever you throw at them without tossing you around painfully in the saddle in the way some ultra stiff sets of carbon rims do. Notably, Reynolds also joined the growing list of wheel manufacturers eliminating bead hooks, and the Endurance 27. 5's now feature a completely hookless bead. We were skeptical at first about this new trend, but with the huge gains made in tire composition over recent decades, the interface between the rim and tire has already improved enough that a hooked rim is nowhere near as essential to holding a tire on a rim as it was a half century ago. During testing, manufacturers Reynolds included are continuously finding that the right hookless rim shape actually creates a smoother ride while you're railing ...
