The TdF pros disagree with you. Yes they can be traditionalist and have "pack mentality", but these people spend literally 6-10 hours on a bike straight. In particular, when you are bonking and trying to keep up with a group or get up a mountain, you become PAINFULLY aware of the deficiencies in your equipment. An extra pound on your bike when trying to keep up with your group up a 8% grade will feel like you're carrying an anvil.
