True that. I used a B17 on the Ride:Well cross-country tour (check it out, they're awesome) and loved the comfort, but for a while I felt like I was sitting on the rail that the rivets attach to on the back. It was uncomfortable. But then I raised my handlebars and raised the nose a bit and things became much more comfortable. I still wish it went back farther, though. I might try a Cardiff someday to see if it helps.

That being said, the B17 is on my commuter now and I love it. It's pretty, too.
