I'm building up my BLT, coming from a Classic. On my old front triangle, the hose guide was an adapter that sat in the rear brake housing stop. On my new front triangle, the guides are disc specific and the old plastic adapter doesn't fit (way smaller than the guide hole). Being my first disc only frame, what am I missing about routing the brake hose? Is there some sort of guide that I'm supposed to use? I'm thinking that the hose is supposed to be held by something so that it does not rub on the guides, but I'm just missing it I guess. Maybe some photos or ideas? Just clueless here...
