And here is what DT Swiss has to say:
The new 240 is developed for riders with the most extreme ambitions. The latest version of the hub is equipped with the Ratchet EXP system to maximize reliability. The increased bearing distance increases bearing lifetime, the straight spring provides more direct engagement, which reduces wear, and a smaller number of parts not only makes maintenance easier but also reduces weight.
- Ratchet EXP (36t unless noted) features a fused threaded ring/ratchet and single spring, reducing the number of components for a lighter and more durable freehub system
- Integration of drive side bearing into threaded ring widens bearing stance, resulting in 15% greater hub stiffness
- With DT’s ratchet system, all of the teeth on each side of the ratchets engage simultaneously every time. This creates much smaller point loads and results in the legendary reliability of Ratchet System hubs
- Affordable Swiss performance
- 6-bolt disc
- Steel cartridge bearings
- Refined end caps allow for easier disassembly
