The DT Swiss 240s Front Hub is the obvious pairing for a 240s rear, but what's less obvious to the uninitiated is that they make a strong argument for the perfect hubs on which to build your ideal set of hoops. Legendary durability, minimal maintenance, top notch quality, and timeless design makes them hard to beat. The 240s front hubs use a forged aluminum shell that houses stainless steel bearings balls and races, which are known for their famous 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. While the front hub you see here has nomenclature that designates it for road bikes, its construction is identical to that of the company's 240s mountain hubs, making these more than strong enough for rim brake mountain bike duty or cyclocross. The DT Swiss 240s Front Hub comes in one color only. It has a standard quick release front axle, and is available in versions that can accommodate 20 , 24 , 28, and 32 hole wheel configurations.
