my IRO Mia frame arrived a few days ago, and i encountered a dilemma when installing my juicy 5's. the cable guides underneath the top tube are spherical, and i'm not sure how i can go about installing the hoses inside the guides. will it be necessary to bleed my brakes to guide that hose through??! these are the first hydro brakes i've installed, and i feel pretty stupid not being able to figure this out. thanks!
