i had 36:18, 2:1 which was (and is) perfect for most stuff and ideal for glentress etc, but i recently put heavier tyres on and got less fit and was struggling a bit on some hills in the pentlands, so went for 36:20 the other night. definitely better, though it’s going to be an arse changing chain length depending where i’m going – not sure i can arrange it to just shift in the dropouts..
is a 69er, so 26 at the back
but anyway, unless it’s technical or crazy steep i would always prefer to get it over with as quick as possible and the 2:1 gearing seems about right
