I'll be honest...I've never actually used clipless pedals. I've never been able to imagine a scenario where they could help short of a race.

10 lbs difference in bikes...the "feel" is what you notice I think, not the actual difference in acceleration. I had a carbon fiber road bike, and it sure FELT like it accelerated faster because I could feel it sort of bucking under me when I pedaled hard, but that doesn't mean I was accelerating any faster.

Ok, I actually just did some calculations. Using some assumed constants (I might have flubbed a unit here, but shouldnt effect it too much...)

Acceleration at 100kg = 1.5 meters/sec2

Acceleration at 104.53kg 1.43 meters/sec2 (difference of 10 lbs)

I don't think that is something that will be noticeable on a commute other than how the bike feels under you.
