I’m told I could be more efficient with saving energy on long rides with multiple climbs using the lower gearing, currently steep hills (ones with 10+ gradients in them) are tough but can be grinded through and eventually recovered from. If there’s is a better combo that would help dial down the effort on those so I can last longer, and cycle further - I’d be into that!

So i'm going to bump this aged thread if I may, as I have a related question:
After decades of fixed I finally built up my dream road bike at the start of last year and have loved every second of it (still ride fixed too though xD) - although as a roadie n00b I installed a standard 53/39 chainset with 11-25 on the back.
It's useable... and has got me through my longest ride of London-Newhaven-London but I've had a fair few riders chuckle and recommended I go compact 50/34.
Now I see videos that 50/34 is dead, long live 52/36 and long cage derailleurs accommodating 11-32...
...Sheldon's calcs show me a ~1kph difference both cruising in a mid gear and in the lowest gear for the same rpm (standard vs compact) but I guess this isn't telling me about the change in effort involved?
Would going 50/34 mean also switching the cassette to 11-28 (max on my derailleur) to make it worth while?
Thinking I may just have to get the new chainset/cassette and bite the bullet, but anymore insight would be soo helpful!!!
(I would ask on roadie forums but I like this corner of teh internet)

Interesting! Sacrifice some top end to allow the cassette to fit with the increased bottom end?
