Discover the New DT Swiss 240 EXP
DT’s redesigned 240 hubs come in the same wide range of options as their star ratchet models but are lighter, more precise, and more easily serviceable.
The Whole Bike Considered
The goal of DT Swiss star ratchets were to provide the best balance between engagement, reliability, and low system weight. With Ratchet EXP, DT Swiss also considered the potential for pedal kickback. Naturally, DT Swiss found that “more points of engagement = higher potential of pedal kickbacks” (dependent on your bike and ride speed).
The 36t ratchet EXP system with less parts allowed DT Swiss to decrease potential of pedal kickback, lower rolling resistance, and lower system weight.
A Simpler Lighter System
With one ratchet fused to the threaded ring, the new system no longer needs two springs to push the ratchets together. This means less parts, and less weight!
Superior Reliability
The ratchets fully engage to create a large contact surface and small point loads, resulting in superior reliability.
Stiffer Bearing Stance
Since the bearing is integrated in the threaded ring, it means a stiffer bearing stance due to the increase in distance between the drive shell bearings.
Simple Endcap Removal
The EXP end caps are notched to allow for a secure fit when installed. Changing the end caps is a simple tool-free procedure. Freehubs are easily swappable and are available for SRAM and Shimano.
Redesigned Hub Shell
DT redesigned the 240 hub shell to fit the new EXP system. 240 EXP is not compatible with 240s hub shells.
EXP for Less
Experience the benefits of Ratchet EXP without the expense of the DT Swiss 180.
Steel Bearings
The new DT240 hubs are made with durable stainless steel bearings.
DT Swiss 240 History
Over the last 22 years DT Swiss has been continuously making improvements to their bearings and ratchet system. The DT 240 hub development process started with DT’s Hügi 98 hub. DT soon developed the Hügi 240, which saw a reduced weight and better star ratchets than it’s earlier version. That hub eventually became the 240 with improved stainless bearings, better component materials, and non-contact seals. With their release of the DT Swiss 240 EXP, DT proves that they continue to be innovators in the cycling industry.
