How do you make an almost perfect all-rounder even better? It's no easy task for the Schwalbe chief developers. However, the result is outstanding. The profile of the Smart Sam is modern and robust at the same time. The compact center ridge ensures a pleasant rolling experience, while the angular outer lugs guarantee optimized off-road grip. Thus, the Smart Sam is at home in any terrain and rolls pleasantly light on the road as well. Version: GreenGuard. Compatibility: Approved up to 50 km/h.
