It's a bit of a minefield on the Jagwire website regards inner and outer cables. I run the Road Pro set at the moment, but am going to change out the Teflon coated inners (both shift and brake) which are black. The black Teflon coating rubs/wears off at points where they attach at the derailleurs and brakes by bolts, so thought that it may be wearing off inside the housing and liners also. I am going to switch them out for some standard slick stainless inner cables with no Teflon coating.

I will spend the next few hours looking at all the different inner and outer cable offerings and try and come to some conclusion
