Sorry, I just noticed this.

The B17 is on one of my bikes, but my main ride now has the B17 Imperial. I was fortunate enough to get in on the testing and have to say, I have been to the mountain top, I have looked down and I have seen the light.

It is one of the most comfortable things I've ever put under my butt.

I haven't done it yet, but I am giving serious consideration to adding a cut-out and laces to my original B17.
