i road the dawes for the heck of it and it was smooth and solid. I did a few comparative runs which i always do on my breezer and was astounded that despite feeling just as fast on the breezer i was intact 2.5+ mph
slower over several 25+ mile routes on similar conditions on the dawes. Note the speed difference is not due to lights (the rides are on a mup), wind (there was none) or time (the rides were a few days apart).
So i'm curious why the speed difference?
The differences b/w the bikes are below. Which is likely to cause the speed difference?
A) weight the dawes is just over 21 pound
the breezer just under 19 pounds. 3/4 pound comes from the wheelset and the remainder comes mostly from the groupset differences.
B) endurance (dawes) vs racing (breezer) geometry
c) stiffness? The breezer and its campy wheels are claimed to be stiffer.
D) lighter and better wheelset. The breezer wheelset is 1750 grams with sealed bearings and the dawes is 2100 grams with the regular ball and cones.
E) groupset: Claris (dawes) vs 5800 (breezer)
INPD, I'm really curious as to how you arrived at the less than 19 lb. figure for your Breezer. Based on your build, my Breezer should be significantly lighter than yours, and I don't think mine weighs less than 20 lbs (though I wish it did).
My wheels come in at about 1/2 lb. lighter than yours and my seat tube is probably 4-5 oz lighter than yours. Call everything else a wash for now (identical groupsets) and my bike should be almost a pound lighter than yours. Using my not-very-accurate luggage scale my Breezer clocks in at over 21 lbs. Say my scale reads heavy by a pound and I'm at 20 lbs or so. My CAAD 10 is probably 3 lbs lighter than my Breezer, and I don't think it's under 17 lbs.
Back on topic, on flats and false flats I'm probably just as fast on my Breezer. I feel noticeably stronger when climbing steeper grades on my CAAD 10.
I will not deny that I'm more smarter [sic], witty, charming and just plain debonair on the Breezer. That is just plain fact.
