DT Swiss Rotor Conversion Kit Ratchet to EXP - Road - Standard Bearings - Campagnolo 12x130/135mm

DT Swiss Rotor Conversion Kit Ratchet to EXP - Road - Standard Bearings - Campagnolo 12x130/135mm

Freehub body to change wheels and hubs with DT Swiss Ratchet System rotor to EXP rotor standard.

Features of the DT Swiss EXP freehub

The new freehub with EXP spur toothing: Lighter, stiffer, more precise and easier to maintain. The strengths of the Ratchet freehub bodies have been further improved with the new EXP technology.

DT Swiss EXP technology:

  • Easy maintenance

    ...through a small change to the end caps.

    An integrated notch, the newly developed shape of the end caps greatly simplifies disassembly, making maintenance much easier.

  • Replacement of the freewheel

    Also now simpler thanks to the simplified disassembly. The tool-free concept allows the conversion to another drive standard within seconds. All DT Swiss hubs with ratchet system can be converted.

  • Less weight

    Not only reliability has been improved. The fusion of ratchet and threaded ring reduces the number of small parts in the system, which is a significant advantage. The previous ratchet system required two springs to function properly because the internal ratchet was not attached to the hub shell. The fusion of the ratchet and the threaded ring in the Ratchet EXP hub not only increases durability, but also reduces the overall number of components by using only one spring, resulting in a reduction in the weight of the freewheel system.

  • Less wear

    A single cylindrical spring provides faster full engagement, increasing reliability. Previous systems required two conical springs to ensure the correct angle between the two pawls. The fixed connection between the inner ratchet and the hub shell of the EXP ratchet 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 area and therefore low surface pressure, resulting in superior reliability. What makes the ratchet system hubs superior is that all the teeth on each of the ratchets engage simultaneously every time. In the ratchet hubs, the area of engagement is rather small. With the ratchet system, the entire face engages, resulting in much lower point loads. The result is the legendary reliability of Ratchet System hubs.

  • Increased bearing life

    By integrating the bearing into the threaded ring, the bearing spacing can be maximized. The increased spacing further supports the axle, resulting in less axle deflection, protecting the bearings and increasing their life. The bearing spacing is limited by the size of the freewheel system. With the previous system, the bearing had to be placed on the drive side next to the threaded ring, which meant that the distance could not be increased. By integrating the bearing on the drive side into the threaded ring, the bearing spacing is increased, resulting in a 15% improvement in axle rigidity.
