Front is a 21'' regular knobbie with some Cold Cutter screws in it
Rear is a 18'' canadian left right with 2 street bike liners and 1 3/4 inch long 1/4 inch head canadian style ice screws. They work decent for your first set and they don't cost the 600 bucks like the real ones do.
I don't need them so up they go for sale.
$100.00 takes em. They are in manchester, nh. I will get some pics up if anyone is interested. I will even mount them for free. I will ship these now. Holla!!!
