What does braze on front derailleur mean.

Band or braze on. This avoids any clamp size issues but requires either a frame with the appropriate braze on or an adapter clamp that simulates a braze on derailleur tab. All that means is that there is a bracket on the frame to bolt the front derailleur to rather than having a clamp around the seat tube. This as the name implies is a band which clamps around the seat tube of the frame.

You can purchase clamps to convert a braze on style derailleur into a clamp mounted derailleur. There are two types of road front mech mounting. Braze on some frames have a front derailleur mount integrated with the seat tube and do not require a clamp those are called braze on front derailleurs. Braze on an alternative to the clamp is the braze on derailleur hanger where the derailleur is mounted by bolting a tab on the derailleur to a corresponding tab on the frame s seat tube.
