An old Norco road bike (Kawamura made) with a 650b conversion and an old Sturmey Archer AW 3 speed hub I salvaged from the bike co-op. I built this up back in 2014 and it's still going strong.
I've got a set of Gravdal 650x38b studded tires for winter duties too
Fast and nimble, easy to maintain, feel good locking it up. Wins all around!
