Heh - I did the same thing. My cross check was pre-loved (or not, since it was sold), but came with a women's B-17. It DID NOT work for me. I ordered the regular B-17 from Wallingford, put it on my bike, and rode 50 miles the next day. I stopped to adjust it a few times, and I do think it broke in my butt a little (but that could have bee the general lack of riding that year). But, I made it. And the 95 degree temperatures ensured it was broken in quickly
