They're not actually made of Adamantium which would probably be heavy and expensive if it were real but the WTB Wolverine TCS Light FR 27. 5in Tires are still rugged, even though they use WTB's Dual DNA rubber instead of space age metals. Dual DNA is better anyway, because it conforms to obstacles while being rugged enough for serious riding. The Light version of the Wolverine uses a more flexible lightweight casing for weight savings in the range of 150g, so it's the perfect weapon for long XC and all mountain races where speed is as important as durability. The Wolverine Light also features WTB's TCS tubeless compatible system, which employs a sturdy but flexible TCS aramid bead so you can run it with or without tubes.
