I think its a must on the older e-chain with the aluminum cross bars, the newer iges e-chain that is all plastic you may get by without it.I've thought about that as well. The wrap costs dang much as the hose. And it makes it harder to get the hose in and out of the e-chain!. But I do think it helps protect the hose. Especially on my Razor 1 that has the old style e-chain.
