I just pulled up Rocky Mountain, and Bikebandit to check you numbers as they seemed high.
Rocky Mountain was $114, and $80
Bikebandit has them for $96/rear in 190/50-17 and $67/front in 120/70-17....
Revzilla, Cycle Gear, Dennis Kirk are the same as BB...

At that price, I may order another set.
Ride safe, Ted
