This is a newbie question.
What do you call those end caps that fit onto the ends of brake and shifter cables to prevent fraying? And what is a good source for buying them? (Online, surely?) My local bike shop charged me 25 cents apiece, which seemed rather steep. That was from their shop supply; they don't sell them as an item and there were none included in the shifter cables I bought.
You'd think a handful of these things would only be a couple of bucks!
