>>1406053You need to have some sort of cable stop for the shifters to actually pull cable, one of my bikes accomplishes this with a bolt on doohickey from Suntour like pic related. That thing has a cable stop for the FD cable housing and it has a guide for the RD cable, if your bike doesn't have a cable stop brazed onto the chainstay it looks like there's a clamp on solution for that too, just search 'chainstay cable stop' and you'll find stuff like next pic related
