The first high performance mountain bike tire with concave studs. The high volume 2.35” casing profile adds float on packed snow, while also adding a flatter contact patch for incredible traction and stability. The tread design of the Nicotine uses siping and open space between lugs to grip and shed snow. 222 lightweight studs with a concave carbide tip and aluminum base are carefully placed across the casing to provide extra assurance when the surface turns icy. Available in 120tpi studded and 120tpi stud-less versions.
