Paul bits come in too many varieties for us to stock. Reasons to order from us: you can combine the order with other stuff you need (saddle, tires, whatever), and you probably learned something interesting or funny or not funny reading this article. It takes a few weeks to get whatever you want from Paul when you order from us, and we won't ship until the Paul thing has landed, even if you also ordered other stuff. That's so you don't get creamed with shipping costs.
Paul's brake cable hangers come in 4 sizes, three different front cable hanger sizes and one rear cable hanger size.
The 7/8" (22.2) is for mounting off the quill shaft of 1" quill stems. The 1" sized front hanger goes in place of a 1" threaded headset spacer. The 1 1/8" one goes in as a headset spacer on 1 1/8 threadless bike. The last one, the rear cable hanger is only for mounting off of 27.2 seatposts.
