Lightweight Micro Spline upgrade for your DT Swiss Ratchet hub.

With the DT Swiss Ratchet LN aluminum freehub body for Shimano Micro Spline, you can upgrade your DT Swiss rear hub for modern 12-speed MTB cassettes while saving weight compared with a steel freehub body. Ideal for bikes where every gram and efficient power transfer matter.

The conversion kit is suitable for DT Swiss hubs and wheelsets with a Ratchet system (toothed discs) and a 12 mm thru axle. It is compatible with 12x142 mm and 12x148 mm Boost rear ends and is installed simply by replacing the freehub body and right end cap. Please note: This is not a Boost conversion kit - converting from 12x142 to 12x148 is therefore not possible.

The freehub body is made of lightweight aluminum with high-quality, rust-resistant industrial bearings. This gives you a precise, durable upgrade for your rear wheel.

Highlights:

• Shimano Micro Spline 12-speed: makes DT Swiss Ratchet hubs compatible with current Shimano MTB cassettes.
• Lightweight aluminum freehub: only approx. 48 g (freehub body) - ideal for lightweight trail and XC setups.
• Easy conversion: replace the freehub body and right end cap, and you're done - no additional special tools required.
• High-quality bearings: 2 rust-resistant, sealed industrial bearings for long service life.
• B-stock: possible cosmetic imperfections, fully functional - an attractive price for a fully usable upgrade.
