EBay all the way for me.
bike wrench
A place to ask bicycle repair questions, and for bike shop monkeys to share advanced non commercial wrenching resources (no YouTube self promotion). This is only for repair related topics.
Have you tried asking a local bike shop? The owner of my favourite spot will gladly assist me in ordering whatever weird thing I'm looking for!
I have, actually, in a few different shops. Apparently Shimano stopped producing that particular part so it's hard to find. I'll have to go ask in some more fancy spots.
Shops with a focus on vintage bikes may have better luck finding rare parts than your LBS.
Great idea!
I'm having trouble even imagining what you want! Like a bullhorn brifter?
I'm currently struggling to find an all black 26.2mm seatpost. I don't use Amazon at all though.
