Details

Old road frames with a braze-on derailleur mount were designed for large road rings. They aren't compatible with sub-compact chainrings.

This adapter for the frame front derailleur braze-on allows you to mount your derailleur lower to get it to work with smaller chainrings.

yes you can use the mount, I would try without first as your front mech mount should have enough adjustment space. SK 25/08/26

Can I use this with an Ultegra front mech on a 2016 CAAD12?

Hi, if your derailleur has braze on mounting as opposed to band on it will work. This adaptor lowers the position of the frames braze on fitting. Thanks 09/04/2020
