Opting to custom build your next road wheelset on a pair of DT Swiss 240s hubs requires no justification. The hubs' timeless design, durability, and reliability make their own arguments, so match your 240s straight pull rear with this DT Swiss 240s Straight Pull Front Hub to make a perfect pair. 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. The minimal shell design remains tremendously strong while maintaining incredibly low weight, thanks to the lack of a flange that would normally be in place to anchor J bend spokes. The DT Swiss 240s Straight Pull Front Hub comes in one color only. It has a standard quick release front axle and accommodates 20 hole rims.
