The no-tool concept allows the tool-free disassembly. Featuring an incorporated notch, the newly developed shape of the endcaps simplifies disassembly significantly and therefore makes the maintenance even easier.
Freehub Body Conversion
The no-tool concept allows the conversion to a different drive train standard within seconds. All DT Swiss Ratchet System hubs can be converted.
The previous Ratchet System required two springs to function correctly as the inboard ratchet was not fixed to the hubshell. The fusion of the ratchet and the threaded ring in the Ratchet EXP hub not only increase durability, it also reduces the overall number of components, utilizing a single spring, resulting in a decrease in weight of the freehub system.
The previous systems required two conical springs which ensured the correct angle between the two ratchets. The fixed connection between the inner ratchet and the hub shell of the RATCHET EXP ensures that the inner ratchet is always aligned at the correct angle. Allowing the use of a single cylindrical spring resulting in a faster full engagement and therefore an increase in reliability.
What makes the Ratchet System hubs superior is the fact that all teeth on each of the ratchets engage simultaneously every time. In the case of pawl hubs, the engagement surface area is rather small. With the Ratchet System, the whole front face engages, creating much smaller point loads. The result is the legendary reliability of the Ratchet System hubs.
The hub stiffness is significantly defined by the distance of the bearings. For optimal performance it is important to maximize this distance, which is limited by the size of the freehub system. In the previous system the driveside bearing has to be placed next to the threaded ring and therefore the distance couldn’t be increased.
The integration of the drive side bearing into the threaded ring increases the bearing distance, resulting in a 15% improvement in hub stiffness.
