i have been upgrading my bike and just purchase the ultegra 6700 groupset which has internal cabling. i've also just purchased the wcs richie carbon bars that dont have holes for the cables. silly question but because the bars dont have the holes for the cables and i'm about to just tape them underneath the bar tape... will this be a bad thing or is it fine to do this and you don't necessarally need bars which the cables can be routed through??????????????
