Repairing Shimano front shifter ST-EF41-L
Can anybody suggest where to get these small plastic parts?


Buy a new shifter.  Shimano does not sell replacement shifter parts, so the only way to get parts is to buy another shifter.  And it's a lot easier to replace the old broken shifter with a new one than it is to take apart the new one, remove the needed parts, and reassemble the old shifter with the new parts installed.
