The DT Swiss Ratchet LN Conversion Kit comes with an 18-tooth ratchet as standard. It's designed to upgrade DT Swiss 3-pawl hubs, like those in the 370 models, into a more reliable DT Ratchet freehub system.

Our research shows that switching to this star ratchet system noticeably boosts performance compared to traditional pawl systems thanks to larger, evenly spread engagement surfaces, making for a smoother ride.

If you're looking to tailor things further, you can upgrade to 36 tooth ratchet units or 54 tooth ratchet units, but keep in mind these are sold separately.

More teeth generally mean quicker engagement, which can be really handy in tricky terrains. Still, the standard 18-tooth setup is pretty reliable on its own, according to our findings.

Just a heads up: while you can easily maintain and adjust the conversion without extra tools mid-ride, the initial setup does require specific tools. The manufacturer mentions needing the HBDT835 Ratchet ring nut tool and HBDT5266 Pawl ringnut tool for installation.

It might be a good idea to get a professional mechanic to handle this part to make sure everything's installed right.

Our research shows that folks generally feel content with the performance boost this kit offers, especially when switching from 3-pawl hubs. There's a noticeable uptick in cycling efficiency and reliability.

But be aware that some have pointed out the cost of additional tools and parts as a potential downside.

In the end, though the initial investment might seem steep, the DT Swiss Ratchet LN Conversion Kit is a solid upgrade for those who want to take their cycling experience up a notch without changing out the whole wheel or hub.

Particularly for serious cyclists navigating tough conditions, transforming a 3-pawl hub into a high-performing star ratchet system might well be worth the cost.
