ARGH! I'm with John on this, it's "put-up-or-shut-up" time, though to be fair he is wrong. . . sort of. I've been staying out of until now since I think I've caused enough controversy this week. I did at the beginning of this discussion say that someone should check Frank Whitt and David Wilson's "Bicycling Science" book. This as far as I know is the only real documented scientific words on the subject, though they're almost 20 years old.

From the wheel section pgs. 106-138 it says on pg. 128 it says, "Although lighter wheels accelerate slightly more quickly for a given power and have lower air drag, they also have a higer rolling resistance on smooth roads because of the larger losses at the point of contact." Basically it comes down to tire pressure has more to do with it. All the things I've read over the last many, many years as a professional mechanic support this. Also remember if it accelerates quicker it also decelerates quicker.

If you want more information on the subject check out the Bicycling Science list archives, buy your own book, call Jobst Bryant or Alex Moulton, but just don't bicker about science with opinions anymore. I'm going to go sit in the sun with a beer and a book, thank you.

enjoy, Brandon"monkeyman"Ives

PS: Can we now get back to bickering about Ken Denny or what whacky people those Ebay folks are?
