Doesn’t matter what the bike is if you know the best way to carry it:
1. Stand on NDS of bike.
2. Point crank down. Hold crank with right hand.
3. Hold fork with left hand.
4. Hoist bike over head, rest down tube comfortably across shoulders. Carry.
Fussy types may want to brush any cack off the down tube first. You can even do this one handed on slightly scrambly bits if necessary. Works best if you have a pack on, but weirdos with roadie jerseys and bottles are probably going to be scared of anything where you have to stop pedalling anyway. 😉
Only place where this technique has failed me is that Loch Lomond bit of the WHW which is like a sort of crap, cold jungle with bendy trees everywhere, so you keep having to take the bike off and thread it through branches and round corners and up ladders and I swear there was a snake pit at one point, bloody stupid place to take a bike, I ask you…
