Pacenti DL31 Rim And Hadley Hub Wheelset

27.5 Components Wheels

Bottom Line

The Hadley hubs are still smooth as silk, and the quiet rear connects up as needed, without any undue lagging. One of the tough things in reviewing these hubs is that they are hard to notice, as they’re ultra quiet and don’t seem to do anything special, and sort of blend into the background of doing their job. When you pay close attention, you discern the quality feel, smooth and fast ride without any drag, which all work in synergy for a pretty amazing hub. They aren’t the cheapest or the lightest hubs in the marketplace, but they’re certainly a bargain when compared to Chris King and Industry Nine, and their longevity gives them a good price ratio. They’re not the lightest hub, but their build quality and robustness and longevity make them a real winner.

The Pacenti DL31 offers an ideal width, which is wide enough for great stability, yet still offers quick and precise steering and cornering, with minimal effort to roll them over. The shape and design of the rims give excellent stiffness and lightness, and the steel eyelets keep the wheels in true for the long haul.

The wheelset is overbuilt and a bit portly, but who cares; they’re monster truck wheels that can run over anything without any noticeable flex, and they sail along smoothly and quietly, and have decent enough acceleration and rolling qualities. The superb Hadley hubs are smooth and drag free, and the Pacenti DL31 has an ideal width and stiffness, and together they make an excellent wheelset.
