Brake Hardware - Cable hanger, rear, Nitto
Everything NITTO makes is deluxe. These are for centerpull or cantlever rear brakes. They mount onto the binder bolt. The big one doesn't have a barrel adjuster (it's not always needed, and mountain bike brake levers have them built-in, and you don't need two). The smaller wirey one does.
Both styles work great, don't wrestle too hard hear. Go by looks. These are truly fine pieces of metal, as fine as anything Nitto makes, just a lot simpler and more affordable than most.
