I believe published catalog bicycle weights have been without pedals for at least the last 20 years.
"Who knows what kind of pedal system the owner wants to use?" was the justification.
Made the bike lighter, saved the manufacturer money, and let the shop sell something high markup.
There was one year when there were several bike weights were published WITHOUT WHEELS, which were optional.....
"Who knows what level wheels the customer wants on their bike?"
Made the specs and price great, but I don't think it went over well.
