I just borrowed a Serfas hard case. It was actually a bit tougher to pack up than I thought it should be. Had problems getting the handlebars positioned where I thought the shifters would be safe, and I'm still unsure about where to position the rear derailleur. It seems a bit vulnerable, so I packed a towel under it to provide support. I took off both wheels, saddle and seatpost clamp (it fit with the seatpost in, but just barely) and I took my handlebars off, leaving the stem/headset in place. I'll let you know in a few weeks if the bike got to Colorado successfully!
