For the experienced all-mountain riders out there, the ones with the scratched calves and elbows: This wheel is for you. The lightweight M 1900 SPLINE 25 withstands the toughest alpine tours. The tubeless ready rim has not only been tested by professional mountain bikers on the trails, but also by our experts in the laboratory. The lightweight straight pull hub contains the know-how of more than 20 years of hub development. With this development DT make sure that the M 1900 SPLINE 25 with you will make the trails in the mountains unsafe for many years.
Straightpull stands for straight, straight spokes. Thanks to this technology it is possible to achieve an ideal balance between weight and stability. Straightpull spokes allow very precise alignment and optimized positioning in the wheel for a stiffer and more responsive wheel.
Straightpull hub technology
Straightpull hubs are designed for straight, straight spokes. They are extremely durable, reliable and can be converted to almost all axle standards.
DT pro lock technology
The screw locking system injected into the nipples enables the construction of extremely durable impellers. DT pro lock nipples prevent the spoke-nipple connection from loosening by itself. The integrated, patented screw locking system in the nipple thread is based on a two-component adhesive. As soon as the nipples are screwed in, an adhesive is activated which cures completely at room temperature after approx. 6 - 7 hours. If necessary, the impeller can be used immediately after assembly. Repeated re-centering is possible without any problems. However, the adhesive strength decreases slightly with each re-centering.
Tubeless tyres offer some decisive advantages over the conventional combination of tyre and tube: The tyre can be driven with less pressure without risking snakebites, providing more grip. The lower pressure also increases ride comfort. The absence of the tube means that there is no friction between the tube and the tyre and therefore less rolling resistance when driving off-road and over obstacles. If tubeless milk is also used, the tyre is also immune to punctures and small cuts. This is a great advantage for all those who like to travel long distances and away from the nearest bike shop.
Tubeless Ready rims from DT Swiss have further advantages over conventional rims. Thanks to the design of their cross-section, the tyre simply pops into place when inflated, so that usually only a normal stand pump is needed. The ingenious profile of the DT Swiss rims also ensures a precise and secure fit for the tyre, even under tough driving conditions.
Rim profile design
The profiles of DT Swiss rims are specially designed for tubeless use. They guarantee a perfect fit and make the installation of the tyre as easy as possible. Nevertheless, it is always possible to use a conventional combination of tyre and tube.
No special tool
No special tools are required for normal maintenance.
