SnakeSkin - in rocky terrain it is a great call!Tubeless Easy/SnakeSkinThe new st andard for our Evo tires. A new sidewall monofilament fabric brings three advantages over the previous SnakeSkin fabric: Even better cut resistance, increased protection and most importantly it allows an extremely easy Tubeless conversion. The use of liquid sealant is neccessary, but otherwise installation is just as easy as with real Tubeless tires.
