Todays mystery object is the dangly bit which attaches a bicycle derailleur to the frame. This particular example was bent in the work bike shed nearly a year ago and proved extremely differcult to replace (been off a second hand French bicycle).
What I’ve learnt:
- They’re called ‘hangers’.
Like an electrical fuse they’re designed to break first in a collision to prevent damage to the frame. However, every manufacture seems to use many different variations, making them differcult to identify and replace.
- An after market has sprung up
After market supplies have moved in to supply replacements; manufactured in small runs.

St John Street Cycles were able to confirm that my example is actually a ‘Number 6‘ and had one in stock.
