M 1900 SPLINE means business. It’s been developed for the new all-mountain bikes. We’ve packed all our expertise into the high-end machined hubs of the M 1900 SPLINE. Forces to and from the hubs are transmitted via our proven straight-pull spokes. The strong, lightweight rims of either 25, 30 or 35 mm inner width offer the best tire support for your prefered tire width and meet all the demands of a tubeless setup and modern MTB tires - they’ll have you flying up and down the mountains.
