The turbo among spike tires. With its spikes, it grips firmly on any icy track. Now new: Ice Spiker Pro in the super-wide 27.5+ variant with 344 aluminum spikes. 27.5+ Larger tire volume for even more performance on the mountain bike: more grip, more comfort, more suspension, more safety. LiteSkin The lightest option. The LiteSkin MTB tires forgo SnakeSkin but still feature the extra-stable tire core. Those who are willing to put in the effort can also convert these tires to tubeless with sealant. However, we cannot guarantee that a LiteSkin tire will be reliably and permanently sealed with standard methods. Evolution Line The best that can be achieved. Highest quality materials.
