I've been using V brakes with travel agents on my bike, but I recently purchased a set of Tektro CR720s to replace them. As my Gunnar does not have a braze-on rear cable hanger, I bought a Tektro rear cable hanger (this one: http://www.bikeman.com/BR7151.html) that hangs from the seatpost bolt.
I put it on tonight, but it's really loose, even when I tighten the seatpost bolt. Is this going to be a problem? It seems like it would get knocked around and throw the brakes out of alignment. Any suggestions for installing this correctly?

What year Crosshairs do you have? I guess the rear brake braze-on is something they somewhat recently added as the Crosshairs frame I purchase this year has one.
Anyway, the hanger being loose is normal from what I've seen. When the brake lever is squeezed and the cable goes under tension, it will no longer be loose except for the side to side play (though it will likely gravitate to one side). The hanger has nothing to do with the brake alignment so as long as you get it set up correctly, the hanger shifting around won't cause any problems.
I attached a picture of my frame just in case you're curious.

The seatpost-bolt-mounted cable hanger is common and works well, and is almost always loose. I have this setup on my toruing bike and it works perfectly 100% of the time.
It will not cause misalignment of the brakes because the amount of force needed to move the hanger is so small that it can easily be pulled back to centre by the brakes (as long as the brakes are properly aligned).
