XC Greatness Awaits

Enter the world of XC with the reliable DT Swiss X 1900 Spline 25 wheelset to focus on the essential moments. The 25 mm wide aluminum rim offers modern tires the support needed to ride low air pressure in order to minimize rolling resistance. The new Ratchet LN freehub system and meticulous wheel building by hand ensure the highest reliability. This allows riders to just focus on the moment — whether it's beating the sweat out of their opponents or beating their own PR.

1900 SPLINE wheels form the first step in the MTB range of DT Swiss. This line strives to equip as many mountain bike riders as possible with wheels they can rely on, therefore allowing them to focus completely on that moment on the bike when one feels completely free. In order to enhance the already high reliability of these hand-built wheels, the new 1900 SPLINE wheel line has been equipped with the new Ratchet LN freehub system.


Aside from providing the legendary sound of DT Swiss rear hubs, the ratchet is also responsible for the appreciated reliability of the freehub systems. Compared to pawl freehub systems, the Ratchet System offers superior reliability due to a larger contact surface area at engagement. Forces can be distributed evenly over larger areas and lower peak loads are achieved. The result is higher reliability and a longer lifetime, allowing riders to focus on the essentials.

What makes the Ratchet System hubs superior is the fact that all teeth on each of the ratchets engage simultaneously every time. In the case of pawl hubs, the engagement surface area is rather small. With the Ratchet System, the whole front face engages, creating much smaller point loads. The result is the legendary reliability of the Ratchet System hubs.


The X 1900 SPLINE comes with a 25 mm wide rim, the X 432. This inner width provides sufficient support for modern tires to ride low air pressure, reducing rolling resistance. Nevertheless, the rim is lighter than a 30 mm aluminum rim. The lower weight is essential for acceleration as the rotating and accelerating mass can be kept lower, therefore the X 432 rim is available only in 25 mm.

The 1900 SPLINE uses rims that are connected with a sleeve joint. Sleeve joint rims use an accurate small aluminum insert which fits in the hollow cavity of the rim and aligns both bended profile ends. Together with height strength structural glue it secures rim joint.

A sleeved rim is more effective in production than a welded rim but fulfills the same testing requirements and additional weight is minimal compared to high end welded rims.
