Serious engineering for serious machines.
Whereas the 240s hubs use a forged aluminum shell that houses stainless steel bearings (balls and races), the 180 revises the entire design of both the shell and its internals. The aluminum flanges remain, but they are joined in the center by a carbon fiber central tube, a structure that sheds even more weight, and we think, looks pretty sweet, too. The bearings, however, are where the biggest improvement is made, upgrading the 240s house-made precision steel balls to ceramic ones, dramatically improving durability and service life of the bearings, while also noticeably reducing rotational resistance. The result is a featherweight hub that rolls with glassy smoothness and can be counted on to last for many, many miles. Further, 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, virtually regardless of riding conditions.
In addition to the way it sings on fast descents, the 180's 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. Finally, to accommodate both symmetrical and asymmetrical rim designs that are becoming more popular as drivetrains increase in number of increments and frames become ever-more advanced, the 180 rear hub's flanges are designed to make it possible to build it to virtually any rim type.
