Ch. Flyer
Hi,
I can't speak about the B17, although I'm planning to order a B17n for a single-speed that's on the list, cutting down the skirts a bit. The Champion Flyer is on my commuter. It's hands-down the best saddle I've ever ridden. You won't feel the springs there until you hit a real bump. Then they come into their own. It's hard to describe but easy to feel. This saddle will never, ever be sold. It's now on an aluminum frame (soon to be sold -- steel is real) and it's part of me. That's literally and figuratively. My advice: go to Wallingford, try one and use the shop's generous exchange policy if you don't like it. The folks there are the best, and the prices are as good as any.
