I mean, obviously, its not a super scientific test, but the common response in forums is to just lose that kg/lg of weight off your body instead. I'd be willing to bet that the single lb/kg off the bike will have more effect than a single lb/kg off your body. That said, in terms of percentages, losing it on your is going to be much better. Generally speaking, I associate losing that weight with also being more fit. So in effect, you're losing the weight, but also increasing your ability to do work. Put them together and you're off to the races.
For me, I went carbon this year. Gonna have to focus on my ability to do work these winter months.
