Simple Maintenance
Our hubs are known for their no tool technology. We found a way to further improve this system and make maintenance even simpler, by a small change of the end caps.
Learn moreFeaturing an incorporated notch, the newly developed shape of the end caps simplifies disassembly significantly and therefore makes maintenance even easier.
Freehub Body Conversion
Simplified due to easier disassembly.
Learn moreThe no-tool concept allows the conversion to a different drive train standard within seconds. All DT Swiss Ratchet System hubs can be converted.
Less Weight
Not only the reliability improved. The fusion of ratchet and threaded ring reduces the number of single parts of the system, which offers an important advantage.
Learn moreThe previous Ratchet System required two springs to function correctly as the inboard ratchet was not fixed to the hub shell. The fusion of the ratchet and the threaded ring in the Ratchet EXP hub not only increases durability, it also reduces the overall number of components, utilizing a single spring, resulting in a decrease in the weight of the freehub system.
Less Wear
A single cylindrical spring ensures faster full engagement and thus increases reliability.
Learn moreThe 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. This allows the use of a single cylindrical spring, resulting in faster full engagement and therefore increased reliability.
Superior Reliability
The full engagement of the ratchets creates a large contact surface and therefore low surface pressure that leads to superior reliability.
Learn moreWhat 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.
Increased Bearing Lifetime
The integration of the bearing into the threaded ring allows the bearing distance to be maximized. The increased distance further supports the axis, which results in less deflection of the axle and thus protects the bearings and increases their lifetime.
Learn moreThe bearing distance is limited by the size of the freehub system. In the previous system, the drive side bearing had to be placed next to the threaded ring which meant that the distance could not be increased. The integration of the drive side bearing into the threaded ring increases the bearing distance, resulting in a 15% improvement in axis stiffness.
