The Vigilante SG1 is a cult favorite among mountain bikers and EMTBs. Square-lugged knobs still deliver unwavering traction, yet with added height to ensure they dig even deeper into loose, unpredictable terrain. Increased circumferential spacing allows the tread to remain clear in sticky conditions as hefty outer knobs protect the sidewall while you send it down the chunkiest rock gardens. SG1 puncture protection runs under the tread cap and has extended bead protection.
