First class all-rounder utilizing Schwalbe's incredibly robust Double-Defense construction: 3mm thick GreenGuard puncture protection coupled with highly cut-resistant Snakeskin sidewall.  Deceivingly fast rolling and efficient, the Smart Sam Plus delivers an unparalleled balance of performance and protection for those riders who demand both!  Equally at home on the road, trail, or bike path, the tightly spaced center-tread provides smooth-rolling speed, while the intermediate and side-knobs deliver assured and confident off-road grip.

Schwalbe E50 rated, and ECE-R75 certified for approved use on Class 3 E-Bikes up to 50km/h.
