So I'm curious, from what I've been told when using Shimano you are supposed to replace your cables completely every 1500 miles. Well I am at about that point, and I'm looking to get my cables and housing replaced. My shifters are DA7900, front and rear derailleurs as well. I'd like to just get all new cables, and I'd like to replace the housing to a red color just for aethestics.
My question(s) are, does it matter what housing to use for the cables? What cables are best to use? My LBS offers I think 3 levels, a crappy one, stainless steel, then a teflon based cable. I don't know anything about cables, let alone if one of those three is what I want. Before I get suckered into paying for anything, just looking to get some advice. Thanks.
