Not an easy task for the Schwalbe chief developers. However, the result is outstanding. The profile of the new Smart Sam is both modern and bulky. The compact centre bar ensures comfortable rolling, the angular outer cleats guarantee optimised off-road grip. Smart Sam is therefore at home in any terrain and also rolls comfortably light on the road. With Addix, Schwalbe offers significantly improved solutions, especially for the service life of the tyres, and not only marks a new performance level for all MTB disciplines with their very different requirements in competition use. For the Addix compound, Schwalbe uses a highly modern and extremely precise mixing technology that is otherwise not used in the bicycle tyre industry.
