Hey Hubber's
That time of the month again!
As you've come to expect, every month we are still doing educational posts around DT Swiss and products using DT Swiss designs.
This time we are covering a new system introduced to the market in 2022 which has superseded the 3-pawl hub internals as DT's most affordable forward drive system:
The Ratchet LN system
Internally, Ratchet LN uses the same mechanism as the well-known Ratchet System. The difference in the system lies in the seal placement. To ensure the convertibility of pawl hubs, the seal had to be fixed to the freehub body on Ratchet LN hubs. Hubs with the classic Ratchet System or Ratchet EXP have their sealing on the hub shell.
The following are a list of hubs and wheelsets in which the Ratchet LN system can be found.
Note that in each of these examples it is the current generation (2022 onward) being referred to
370 hubs
360 hubs
1900 series wheels
1800 series wheels
Certain OE models of wheels such as Roval, mentioned previously
How to identify DT Swiss Ratchet LN Hub Internals
(In order of importance):
End caps removable by hand No cone wrench required. If it doesn't come of by hand it's not DT Swiss. Period. Stop right here. Do not waste any more time.
Internals are made up of two unmistakable ratchet rings
Hub seal is located on freehub (arrow)
Freehub and end cap have "Ratchet LN" laser etched on
Upgradeable from 3-pawl
Further to this, should you be running the 3-pawl system in your hub currently, you can upgrade to the new Ratchet LN system
The Ratchet LN upgrade kit includes the threaded ring, ratchets with 18 teeth, spring, shim ring, spacer and the freehub body. It is available with a standard Shimano HG, SRAM XD and Shimano MICRO SPLINE freehub body. For conversion, the DT Swiss 3-pawl ring nut removal tool and the DT Swiss Ratchet ring nut removal tool is required.
Until next time hubbers!
