pretty much anything I’d ride normally I can get up with 34/23
Which is virtually the same gear as 39/27? Not particularly tall, albeit taller than is fashionable I concede!
I think you all took the “spinning” bit too literally
Eh? You said:
50-25 has me spinning up a local 1:5 gradient.
There’s not really any room for interpretation there! This:
I’m happy to push a 34:25 gear up a relatively short 20% climb
Is very different altogether.
End of the day it’s horses for courses innit. Chap I know has just built a Dogma, lovely bike, went with 53/39 and 11-25, because it looks good (which it does). He’s grinding away on the climbs, but he still gets up them. I suspect many people would manage with taller gears if it’s all they had, but for very legitimate reasons they’re disinclined to try.
