The shop is making you pay the “janky e bike tax”. No matter. Any 7-9 speed Shimano derailleur will work, and most off brand 7-9 speeds. Acera M-3000 is a good choice, but any will work. Feel free to send any specific models you aren’t sure about.

I think it’s important to note that this isn’t just throwing money in to a hole. The stuff we donate is mostly made in Canada, so there’s some economic kickback

or you could just teach your children not to play on the tram tracks. the world is full of pointy edges. must we bubble wrap them all?
