Built for the way you want to build it.
Designed for use with CenterLock rotors, straight-pull spokes, and mountain bikes with 142mm rear thru-axles, the DT Swiss 240s Straight Pull Rear CenterLock Disc Hub is built on DT's proven 240 platform, and it's ready for whatever you are.
The 240s rear 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. In addition to the way it sings on fast descents, the 240s' Star Ratchet freehub system is legendary for its simplicity, durability, and instant power transfer. The ratcheting freehub offers tool-free access for routine cleaning and lubrication, and the freehub body is made of aluminum to maintain a lightweight package.
Thanks to the fact that we now live in a world of 10- and 11-speed drivetrains, many hub and wheelset configurations have asymmetrical, highly dished rear wheels. This asymmetry often doesn't allow adequate spoke tension on the non-drive side of the wheel, causing unequal loads and an inherently weak wheel. DT Swiss concentrated on this problem when it developed the 240s Rear Hub. Its optimized geometry improves the wheel's symmetry, giving you tons of reliability and resistance to detensioning. The configuration for straight-pull spokes saves further weight, too, as the flanges that normally would anchor J-bend spokes are eliminated.
