The X 1900 SPLINE has everything a modern wheel needs. The strong, lightweight rim guarantees optimum acceleration, while the high-precision freewheel minimizes resistance and maximizes lifespan. The components are held together with 28 extremely durable straightpull spokes. Maximum trail fun without breaking the bank. The high-quality finish and the classy look will turn heads. Unfortunately for your competitors, they’ll only get a short, jealous glance as you fly past them.
Pro Lock is a process where a patented, dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and starts to harden. Retruing the wheel is still possible after the adhesive has hardened completely, with only a minimal decrease of its thread-lock function.
Each component of the pawl hubs has gone through a demanding development process and is constantly optimized. Two examples are the low-friction V-seal and the high-quality, easy-to-replace ball bearings, which are pressed into the hubshells with thousandth-of-a-millimeter precision. Similarly, the two-piece steel and aluminum freewheel body stands for the perfect combination of weight and strenght. As a single component it represents all the know how that makes the reputation of the term «Swiss engineering». All of DT Swiss' efforts serve one purpose – to build light, reliable hubs leading to less time in the workshop and more time in the saddle! High end catridge bearings throughout. Low friction thanks to single sided seals. 2080 N load capacity per bearing. Engages with the pawls, transfers torque to the hubshell 400 Nm torque tested. Three hardened, high precision pawls engage with the thread ring. Hard and resistant pawl material. A steel section of the rotor is used for this high stress component - 1000 N/mm2 tensile strength. And the alloy section of the rotor achieve an ideal strength to weight ratio, aluminum is used for this lower stress component - 25 g alloy section only. The annular spring pushes the pawls outwards to engage with the thread ring - tested to 13 standard lifecylces of a wheel.
