Not an 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 smooth ride, while the angular outer lugs guarantee optimized off-road grip. Thus, Smart Sam is at home in any terrain and rolls pleasantly light on the road as well. Performance Line. Excellent quality for intensive use. Here you get the most tire for your money. With Addix, Schwalbe offers significantly improved solutions, particularly in terms of tire longevity, and sets a performance level for all MTB disciplines with their diverse requirements, not just in competitive use.
