...with the downside being that it was in my face on a 5 degree climb (according to my inclinometer) and I slowed down to 7 mph - I already was a little pooped going up a 13 mile ascent at 12 mph in 95 degree heat.

I blow as a climber but nobody goes down moderate hills faster on my route - I seem to smoke everybody - must be the big rider's curse and blessing respectively..

P.S. My Allez does not vibrate or shimmy at all at high speeds thanks to - I believe - the huge 62 cm frame and 190 mm head tube!
