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 30mm rim width, which eliminates tubeless tire burping and allows you to reduce the tire pressure to keep you in greater control. Twenty-eight cold-forged spokes tension the rim in a DT Swiss straight pull hub to provide the ultimate balance of light weight and stiffness. No matter how steep or how rocky your trail, the M 1900 SPLINE is more than up to the challenge.
