My son's bicycle gear shifter SHIMANO ST-EF41-L (front 3 speed) malfunctioned (Both levers became free). I disassembled it and found 3 very small plastic parts on the bottom side of the shifter were broken and the spring ring which attaches the 3 plastic parts to the axle were out of place.

Can anybody suggest where to get these small plastic parts? Thanks

  • Broken small plastic pieces suggests it is Unserviceable and needs replacement. Good news is shifters aren't too expensive. Look around for a local bicycle cooperative who may be able to help with used 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.

  • Note that most shops seem to sell these shifters as pairs but, if you can find somebody selling just the left shifter, they're pretty cheap: only about £13 ($17US; 15EUR) online. Also, a physical bike shop would probably be willing to split a pair for you since they'll almost certainly be able to sell the other lever to somebody else. Commented Aug 8, 2018 at 18:40
