Where should front derailleur be placed?
The front derailleur cage should be approximately parallel to the chain If the derailleur cage is rotated too far from this position, it will shift poorly If the derailleur mount is a clamp type, its rotation can be changed Generally, the outer cage of the front derailleur should be aligned to the chain
What angle should a front derailleur be?
