The DT Swiss Ratchet LN freehub body is an essential upgrade or replacement part designed specifically for entry-level DT Swiss hubs, such as the 370 series. This system allows riders to transition from a traditional 3-pawl mechanism to the more reliable and high-performance Ratchet System. By utilizing the same internal components as higher-tier Ratchet hubs, the LN version provides simultaneous engagement and increased durability for off-road riding.

Constructed from lightweight aluminum, this freehub is designed for the Shimano Micro Spline standard, accommodating modern 12-speed wide-range cassettes. It is compatible with 12mm thru-axle systems and fits rear hub spacings of 142mm or 148mm (Boost). The kit includes the necessary end cap, ensuring a seamless installation that optimizes the engagement and longevity of your rear wheel's drive system.
