I looked for Sheldon Brown at Interbike. I did see him across the way once, but he was whizzing away on his electric scooter and he disappeared.
I missed this earlier, but Sheldon posted his own Interbike 2007 updates at his website. He notes the trend toward commuter bikes, especially high end expensive commuters bikes, and he likes what he sees.
Sheldon highlights a handy-dandy emergency derailleur hanger from Wheels Manufacturing that might have come in handy when I trashed my hanger. But then again maybe not, since I also destroyed the rear derailleur and my chainring bolts.
There's lots of good stuff at Sheldon's Interbike 2007 report. Give it a read when you have the chance.
