Here is an interesting article from the BMJ
"Bicycle weight and commuting time: randomised trial
Objective To determine whether the author’s 20.9 lb (9.5 kg) carbon frame bicycle reduced commuting time compared with his 29.75 lb (13.5 kg) steel frame bicycle."
- and if you can't be bothered to read it, the conclusions were:
"Conclusions A lighter bicycle did not lead to a detectable difference in commuting time. Cyclists may find it more cost effective to reduce their own weight rather than to purchase a lighter bicycle."
