I stand corrected on the head tube angle. My experience has been that TT/Tri bikes felt twitchy compared to road bikes so I falsely assumed it was due to steeper head tubes. I'll need to see what the ratio is of wheelbase to trail.

**Update**
Apparently fork rake is also slightly greater on a few of the bikes I checked (Cervelo, Kestrel, Quintana Roo, Jamis) so trail will be reduced and the handling should be "more predictable; slower" than a road bike. I find this odd since my experiences/impressions have been to the contrary.

I apologize for my incorrect assumptions.
