Erk, torn between my love for old Konas and my equally great love for my Thorn Raven Nomad.
The Thorn is more bike than I'll probably ever need (I've lost whole 45l panniers of motivation in recent years) but it rides sooooo sweetly and can handle silly loads (30ish kilos of shopping, or the Brompton I carried home the other day on the rack).
Round the world it would just be perfect.
The Kona would make a really great commuting bike, or a lightweight singlespeed, but perhaps wouldn't be ideal loaded up.
I recently hybridisered a stunning Explosif…
…which was an unforgiveably criminal thing to do!
