Rainy days, wet soil, rocks, and roots. The tubeless tires somehow find grip. The M 1700 SPLINE 25 comes stock with tubeless rim tape and valves, just the right tool for demanding trails. The wide rim gives the tire that decisive little bit more support while the Ratchet System freewheel ensures safe engagements even in the most adverse conditions. Finally, being a lightweight helps you to quickly get back up to that trail entrance, to start the slip-and-grip fest all over again.
