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)
