In converting a flat bar road bike to drops I have almost all my questions answered except for something I just noticed. The bike has a Deore FD and the cable routes under the shell of the bottom bracket, runs straight up along the seat tube, around a pivot on the derailleur, then 90 degrees out to the clamp bolt. I have a Tiagra FD I want to throw on there but it does not have that pivot point, which means the cable will go off at an angle from the guide directly to the clamp bolt on the FD. Is there an issue here with how the cable will run through the guide? Will there be excessive where on one side of the guide and do I need to find one that will direct the cable properly to the FD?
