Lighter, stiffer, more precise and easier to maintain: the 240 EXP hub from DT Swiss
Swiss accuracy, from high-precision machining to perfect assembly, has been combined with intelligent detail solutions to make the 240 hubs what they are today: a legend. The strengths of the new 240 hub are further enhanced with the new RATCHET EXP technology. The extremely reliable freewheel system ensures direct power transmission without losses. Just what athletes want: perfect transmission of their power and the reliability allowing them to focus on the ride.Product features - DT Swiss 240 EXP Road Non Disc Rear Hub

Technologies
Increased Bearaing 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.
Increased Bearaing Distance
The 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 axle stiffness.
Faster Full Engagement
The previous system required two conical springs to ensure proper alignment of the two ratchets. The fixed connection of the inner ratchet of the RATCHET EXP with the hub shell allows to use only one cylindrical spring, to ensure proper alignment of the moving ratchet. This results in faster full engagement and eventually reduces wear.
Large Contact Surface
What makes the Ratchet System superior is the fact that all teeth on each of the ratchets engage simultaneously every time. In comparison, the engagement surface of pawl hubs is rather small.
With the Ratchet System, the whole front face engages, creating much lower surface pressures. The result is the legendary reliability of the Ratchet System.
Superior Relability
The full engagement of the ratchets creates a large contact surface and therefore low surface pressure that leads to superior reliability.
Less Wear
A single cylindrical spring ensures faster full engagement and thus increases reliability.
Less Weight
Not only the reliability improved. The fusion of ratchet and threaded ring reduces the number of single parts of the system what offer san important advantage.
Less Parts
The previous Ratchet System was constructed with two springs as the inner 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, making this hub family even ligther.
Simple Maintenance
The no tool concept thought ahead. With a small an clever innovation, DT Swiss make maintenance even simpler.
Incorporated Notch
Featuringan incorporated notch, the newly developed shape of the endcaps simplifies disassembly significantly and therefore makes the maintenance eveneasier.
