I bought two Tacx Tao cages for my road bike, I can get one to fit on the down tube, but the one for the seat post tube doesn't fit. The clamp for the front derailleur is in the way of that extended part on the bottom screw hole as you can see in the picture. How can I get it to fit properly? Can the FD clamp be moved up without affecting the shifting or will I have to cut that extended part off or something? I'm pretty new to cycling so I don't really know much about working with bikes.
