Thanks for your feedback. I just remember braking fairly hard on two successive switchbacks and starting to accelerate after the final turn, hearing a pop, feeling the front wheel turn abruptly to the left and falling. I don't recall hitting a pothole or anything on the road. I just inspected the wheel which is pictured below. The tire has partially rolled off the rim. The Bontraeger SL tube has a 12 inch linear laceration along the seam. There doesn't appear to be any damage to the rim nor broken spokes. I'm 175 pounds and 6ft tall.
A friend just sent me a link to this discussion on the differences of brake pads for carbon rims: http://glorycycles.blogspot.com/2010/11 ... e-pad.html
With the timing of the blowout, I think it was most likely due to rim overheating causing tube overinflation. My front wheel tire was inflated to 105 psi the morning of my ride. My concern is that the newly developed ENVE brake pads do not dissipate heat effectively as compared to the yellow stops that I've used extensively over the past year including last year's Markleville's Death Ride where I used Edge carbon wheels as well.
