Regardless of changing axle standards, the J-bend DT Swiss 240s Boost Disc Front Hub remains a staple for custom builds. The only difference between these and the standard 240s model is that they take advantage of 110mm Boost spacing in order to improve the spoke bracing angle and create a stiffer overall wheel.

Despite that axle expanded footprint, the 240s Boost hub is still built with a forged aluminum shell that houses stainless steel bearings (balls and races), which are renowned for their durability. And thanks to the DT Swiss labyrinth seal system—non-contacting seals that utilize an asymmetrical path to resist moisture, muck, and grit—your bearings will keep their magical smoothness over the long haul.
