This guide is for cyclists with DT Swiss 3-pawl hubs looking to upgrade to the reliable DT Ratchet freehub system. The key benefit is enhanced durability and engagement with DT Swiss's proven technology. A potential caveat is that this kit converts existing 3-pawl systems; it does not replace the entire hub. The Ratchet LN Conversion Kit allows for a seamless transition, offering improved force distribution and reliability over traditional pawl systems.

The Ratchet system offers simultaneous engagement of the ratchet faces, distributing force over a larger area. This leads to greater reliability and durability compared to 3-pawl systems, where stress is concentrated on smaller points.
Yes, the Ratchet LN system is modular. You can upgrade the included 18-tooth ratchets to 36-tooth or 54-tooth ratchets (sold separately) for a faster engagement angle.
Basic bicycle tools are usually sufficient, but a DT Swiss specific hub press or cone wrenches may be helpful for proper disassembly and reassembly. Referencing the official DT Swiss manual is recommended.
No, this kit is specifically designed for DT Swiss 3-pawl hubs that are intended for this conversion. It is not a universal upgrade for all DT Swiss hubs.
This specific product is for the Shimano HG (Hyperglide) freehub body standard.
Service intervals depend on riding conditions, but regular cleaning and re-greasing (using DT Swiss freehub grease) every few months or after significant exposure to dirt/water is generally advised.
Ensure the ratchets are properly lubricated with DT Swiss freehub grease and that they are correctly seated in their respective driver bodies. Check for any debris or damage on the ratchet teeth.
The amount of grease on the ratchets can affect noise. If excessively noisy, try reapplying a thin, even coat of DT Swiss freehub grease. If it's suddenly much louder, check for proper seating.
Verify that the entire Ratchet system is correctly installed and that the ratchets are fully engaging with the drive ring. Ensure no components are missing or improperly seated.
Refer to the official DT Swiss installation guide. Ensure you are using the correct tools and handling the delicate ratchet springs with care. If problems persist, seek assistance from a qualified bike mechanic.
Compatibility: This kit is specifically designed to convert DT Swiss 3-pawl hubs to the Ratchet system. Ensure your existing hub is a compatible DT Swiss 3-pawl model before purchasing. It is intended for Shimano HG freehub bodies as specified.
Setup: Installation involves disassembling the rear hub's freehub body, removing the existing pawls and springs, and installing the new Ratchet system components. It is highly recommended to refer to the official DT Swiss installation manual or consult a professional bike mechanic for correct assembly. Proper lubrication with DT Swiss freehub grease is essential during installation for optimal performance and longevity.
Care: Regular cleaning of the ratchets and freehub body is advised, especially after riding in wet or dirty conditions. Periodically check for wear and re-grease the ratchets as per DT Swiss recommendations to maintain smooth operation and prevent premature wear. Avoid using harsh degreasers directly on the Ratchet system components; a light wipe-down with a clean cloth and appropriate lubricant is generally sufficient.
