A few grams of weight does not have enough impact TT bike performance enough to make it worth shaving 100 grams if it risks reliability.
Yes there is, I and many people have directly measured it.
1. they are a little lighter. This doesn't matter nearly as much as most cyclists think, but it does matter a bit. If you race competitively in the mountains, you might care.
2. There is more design freedom for shaping them aerodynamically. This makes a bit more difference than weight, and if you are competing you definitely want it.
Bikes that need to be durable use different types of fibers that can bend more before cracking, and may include layers of kevlar or other composites with more 'toughness' in key areas. My wife has a carbon fiber mountain bike and has been racing every weekend, winning, jumping, crashing, riding every day, for 3 years now, bike is fine.
Another knock against gasoline is that you spend about 1 EV battery pack of energy to refine a cars tank of gasoline from crude oil in the first place.
Some EVs like Tesla now use a separate lithium ion 12v battery that should last forever, instead of a lead acid 12v battery with a limited life span.
Maybe you are at a higher level than them though.
imho, I fault the EPA for not having a sensible highway range/city range as a standard, then none of this would be an issue
