Q about replaceable derailleur hangers
I have nothing in my fleet with a replaceable derailleur hanger. (Everything is steel, brazed into the steel stays.) My understanding is hangers are in some sense "sacrificial." They break, not your expensive frame or derailleur. Am I more-or-less right about the rationale?
If so, I'm totally confused about an email I got from Silca touting titanium derailleur hangers. I can't get to the Silca site just now, but it's this URL: https://silca.cc/collections/derailleur-hanger Wouldn't replacing typical aluminum(?) derailleur hangers with titanium increase the odds that something much more precious is sacrificed in case of a crash or other unanticipated problem?
