The Whole Bike Considered
DT built the new Ratchet EXP system with an attention to detail that went far beyond the hub – it considered how the hub would fit with the whole bike system. DT’s new 240 hubs come 36t standard. DT Swiss chose 36t as they felt it was the best balance between engagement, reliability, and weight, by calculating for backlash and pedal kickback. DT’s conclusion was that “more points of engagement = higher potential of pedal kickbacks” (dependent on your bike and ride speed). They also factored in that their 36t system is lighter than their high engagement 54t 240 system.
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!
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

The new DT240 hubs are made with durable stainless steel bearings.
