Bikes at Work trailer to haul my race bike. Not like it was terribly involved--most of the work is done by a Saris fork mount which does a great job of holding the bike in place. I have to wrap the front wheel in a towel (not shown) to keep it from chewing the heck out of everything else while I'm towing. Which brings me to my safety message: it's a rare interaction with ice-racing tires that doesn't involve bloodshed; those babies are sharp!
Which is, of course, the point. With the number of studs I had in these tires, I had incredible grab even on pure ice-rink conditions. I could come screaming into a sharp corner, stick out my inside foot and get off the saddle towards the inside, and pretty much lay the bike down to horizontal without losing control. Though that technique requires building up a good head of steam into every corner, which would require that I be in a little better race fitness than I actually am, but even with both feet on the pedals I could lean the bike over pretty well. I was able to make plenty of outside-of-the-corner passes around riders who were tiptoeing around the track on their factory studded tires.
Altogether it was another fun project, and I highly recommend giving it a shot. Just be prepared to set aside a couple weekend afternoons and have your work gloves handy!
[Edit, Feb 14, 2012--Here are a couple shots of me trying to lean it over on a frozen lake in northern Minnesota on a subzero day. The ice was so hard because of the low temps that I couldn't really pitch it in, but you get the idea...]
