This lightweight alloy freehub body is designed for use on DT Swiss Ratchet EXP compatible hubs, offering enhanced performance and simplified maintenance.
The refined endcaps simplify tool-free disassembly. The no-tool concept allows for tool-free disassembly, and the newly developed shape of the endcaps, featuring an incorporated notch, simplifies disassembly significantly, making maintenance easier.
The no-tool concept also allows conversion to a different drive train standard within seconds. All DT Swiss Ratchet System hubs can be converted.
The fusion of the ratchet and the threaded ring in the Ratchet EXP hub reduces the overall number of components, utilizing a single spring instead of two, resulting in a decrease in the weight of the freehub system while increasing durability.
The fixed connection between the inner ratchet and the hub shell ensures the inner ratchet is always aligned at the correct angle. This allows the use of a single cylindrical spring, resulting in a faster full engagement and an increase in reliability compared to previous systems requiring two conical springs.
The full engagement of the ratchets creates a large contact surface and therefore small point loads, resulting in superior reliability. Unlike pawl hubs where the engagement surface area is small, the Ratchet System engages the whole front face, creating much smaller point loads.
The integration of the drive side bearing into the threaded ring increases the bearing distance, resulting in a 15% improvement in hub stiffness compared to the previous system where the drive side bearing had to be placed next to the threaded ring.
