DT Swiss X 1900 Spline Boost wheelset

The sturdy DT Swiss X 1900 wheelsets, designed for use from cross-country to trail riding, feature a 25 mm rim width and the new Ratchet LN freehub system. Thanks to the DT Swiss hubs with Swiss precision ball bearings and the lightweight rims, the X 1900 wheelsets offer excellent acceleration with very good stability. The X 1900 Spline makes it easy to get started in the world of cross-country. The 25 mm wide aluminium rim provides modern tyres with the necessary support to ride at low tyre pressure, thereby reducing rolling resistance. The new Ratchet LN freehub system and the meticulous hand-built construction ensure maximum reliability. This allows the rider to focus entirely on the moment – whether it’s about making their rivals break a sweat or beating their own QOM or KOM.

Boost Standard:

The thru-axle standard requires new hubs. The wider hub shell with the flanges positioned further out enables wheelsets with greater lateral stiffness. On Boost hubs, the brake disc mount is also positioned further out. Consequently, these hubs cannot be fitted to frames with a narrower mounting dimension.

DT Swiss 1900 Spline hubs:

DT Swiss straight-pull hub bodies for the Spline wheelsets require minimal material, allowing them to be constructed to be lightweight yet stable. With the optimised hub body, specifically designed for extreme braking forces, and the reinforced flange, DT Swiss provides the perfect foundation for extra-stable wheelsets. The hubs on the Spline wheelsets feature a Centerlock brake disc mount; adapters for 6-bolt disc brake discs are included.

DT Swiss Ratchet LN freehub body:

The proven DT Swiss Star Ratchet LN system with the toothed freehub body allows for easy conversion to various axle or rotor standards. The DT Swiss Ratchet LN rear hubs can be easily adapted to the various standard cassette mountings.

DT Swiss X 1900 Spline 25 rims:

Fitted with the lightweight (490g) and sturdy X 432 rim from DT Swiss, built for tough cross-country and marathon use, the DT Swiss X 1900 offers excellent acceleration and high stability. With a 25 mm internal rim width and Crotchet Tubeless TC rim technology, tyres from 2.0 to 2.6 inches wide can be fitted. Thanks to hooked rim spokes, the DT Swiss Spline rims are ideally designed for tubeless use. Tubeless rim tape and valve are included in the scope of delivery

DT Swiss Champion Straight Pull Spokes:

To achieve a good balance between weight and stability, Champion straight-pull spokes are used in Spline wheelsets. They are more stable than conventional spokes yet can still be trued and replaced using standard tools. The straight-pull lacing allows for precise placement and alignment of the spokes. This optimises wheel stiffness and eliminates any unwanted stress peaks.
