Derailleur Clamp Adaptor for braze-ons

Just a curious question, is this a good way to go? I was thinking it would just be another component that might fail.

If you need a braze on get a braze on. Is there something I'm not thinking of?

I can see another adjustment direction, but that's as far as my thinking takes me.

Thanks folks.

It's a non-issue. Essentially you're just replacing a mounting point that is brazed or welded onto the frame with a clamp. Functionally they are equals.

I prefer "braze-on" type front derailleurs mounted using an adapter clamp. The clamp is a one-time purchase for any given frame and replacement braze-on derailleurs are a bit less expensive than clamp-on types. Also, during overhauls, you can remove the derailleur for cleaning and replace it with no need for realignment or adjustment if you don't disturb the adapter.

The real problem with tabs brazed on the frame is they limit adjustability so you have less choice of chainring sizes. For odd shaped, non-round or tapered seat tubes you may have to have a braze-on tab. For round tubes, the adapter gives you more versatility

The adapter clamps are very strong and never fail unless you crash them into something. That part is a non-issue.
