My normal Saturday nights involve staying in and working on bicycles, last night was no different. I disassembled, cleaned and overhauled my first New Departure model "D" coaster hub. It was fun, but a little frustrating at times. The brake plates were kinda tricky. I was wondering, is there a way to date these hubs, it may help me date the entire bike. I read the brake arm can give an indication, but I am unsure. It is a silver brake arm with "New Departure Brake" stamped into it. It is a skip tooth hub if that helps any. Thanks for any help you can provide!
