If your bike now has a band mound FD, than it almost surely lacks a braze-on fitting to accept an FD. You can either use a band mount FD, or a braze-on FD with a clamped on braze-on adapter

Your question is further evidence that you are not well enough informed to be spec'ing your own bike without knowledgeable assistance. It shows that you lack even the most fundamental knowledge about bikes. I don't say this to insult you or put you down, but to strongly suggest that you'll need help installing the Force group you've been asking about.

Given that you'll need a local expert, or mechanic, than I suggest you consult with that person BEFORE buying a group that may not suit your needs.

Feel free to disregard this advice. It's your bike and your money, but you'll be doing yourself a serious disservice by going ahead on the skimpy patchwork knowledge you're accumulating via your questions on the forum. The issue isn't the questions and answers, but that we can't see you or fit you properly via a forum, and you have no idea of the other questions that may be pertinent.

For my part, I don't know whether I or others here are helping you or doing you a disservice by enabling you to make what could turn out to be poor decisions regarding your component choices.
