Yes a gravel 46/30 crankset sounds much more workable.

175 also sounds very long. How tall are you? I’m 190cm and use 172.5 cranks.

Also - your legs are not a fixed quantity for eternity. If you do more work, especially deliberately using lower cadence, hight torque at times, they will get less thin.

cyclezen The bikeradar quote - was that for the model year we’re talking about? Cube were definitely using pressfit BBs on all their road bikes up until 2017.
