All-mountain bikes are becoming longer, slacker and faster. The M 1900 SPLINE 30 is our answer to these developments. The rim is very durable and offers a 30 mm rim width, which eliminates burping and allows you to reduce the tire pressure to keep you in permanent control. 28 cold-forged spokes tension the rim in a DT Swiss straight pull hub to provide the ultimate balance of weight and stiffness. No matter how steep or how rocky, the M 1900 SPLINE is more than up to the demands of modern bikes and bikers.
