Considering all top tier carbon bikes are well below the UCI limits, half pound means nothing when Pros are adding weights to their bike to make them heavier...
And when recreational bikers who are riding 14lb pounds can claim they can ride faster than a 15lb UCI Pro cyclist, then they can talk about how much of a difference half pound makes when they buy their water bottle cage.
