rowan asked how do i tell there are meth addicts in every county in america?
watching the national sherrifs association on C-Span, and the president of the association spoke out how meth has affected every county in america...
A Kryptonite Mini U-lock mounts in its bracket nicely from the seat tube towards the seatstay. add a stout cable and you are pretty much golden for a lot of locking situations out on the road.
if the lock weighs a pound and a half, pretend your bike weighs a pound and a half more than it really does. I ride with a mini U-Lock mounted this way in the city, it pretty much becomes part and parcel of the bike.
