Braze On Front Derailleur for Roadbikes
Race bike front derailleurs function like normal derailleur gears. A shift fork is moved to the right or left and thereby “throws” the chain on a smaller or larger chain ring. The diverter should be warp resistant and have firm bearings. As opposed to front derailleurs with clamps, braze-on front derailleurs do not have a separate clamp, because they can be directly fastened on a special fixture at the bike frame.
