DT Swiss Micro Spline Ratchet LN Upgrade Freehub Kit (Shimano Micro Spline Light Aluminium)

- Pawl freehub systems create relatively small engagement surfaces, which result in higher stress on the contact area. - The Ratchet System is extremely reliable due to the simultaneous engagement of the ratchet faces, distributing the force evenly over a large area.
- In addition, the Ratchet System is modular, so the engagement angle can be increased by replacing the included 18 tooth ratchets with 36 or 54 tooth units (sold separately).
- DT are the original ratchet hub innovators, with over 25 years of development and refinement behind it no other manufacturer has matched DT's system for ease of service, reliability and durability.
- Tool-free servicing concept make maintenance quick and simple, even mid-ride in a pinch.
- LN system is specific to 370 hubs such as those found on 1900 series DT complete wheels, the LN freehubs are not compatible with standard Ratchet or Ratchet EXP hubs.
