How can you make an almost perfect all-rounder even better? No easy challenge for the Schwalbe senior developer. The result however, is outstanding. The tread of the Smart Sam is modern and balanced at the same time. The compact central rib provides comfortable rolling; the edged outer lugs guarantee optimized off-roadgrip. For this reason Smart Sam is reliable in every condition and even rolls well on roads.**Features:*** SIDEWALLS (Performance Version): LiteSkin which offers light, thin sidewalls, for weight saving and reduced rolling resistance* COMPOUND: ADDIX high performance* TPI: All Versions 67 TPI* WEIGHT: 660g* E-Bike: E-25* Maximum load: 100kg**ETRTO*** SCM8780: 54-584* SCM8781: 57-584* SCM8782: 60-584* SCM8783: 65-584* SCM8784: 54-622* SCM8785: 57-622* SCM8786: 60-622* SCM8787: 65-622
