Any leads on the smallest (in teeth) freewheel available for a normal track hub? (in this case a Phil Wood Kierin hub)
It's running a 12t fixed at the moment which is dandy but I'd like to try a free-wheel set up for longer rides. I recall seeing evidence that the 14t is the usual smallest but 13's can be had - I just can't remember where I read it or who makes the smaller ones.
I don't want BMX ones as they're too small.
Oh - this being for this - my crazy fixed Brompton folder:
