My question is how much of a difference does it make. So here's the two rides (just going to work...aka downhill). Not really that different. If you look at the moving speed...the road bike is just 1.7 mph faster (moving speed). And you could argue I knew I was doing this comparison....so I might have been going for it a bit.
The real test is really how the weight will affect the climbing performance on the way home. There's no doubt its easier to roll less weight up a hill (darn physics). My question is does it really matter on a 11 mile round trip commute in terms of time / effort. I don't think so, but we'll have to see what the numbers say tomorrow.
