I know that this post is late but I am still using my old Tour Master Expandable Mag Bag from Jan '96! This is the fourth bike it has been on and has never left a scratch or the bike even through high speeds, rain, and wind. It spends it's off bike time stuck on the side of my filing cabinet because it looks cool there. I have even sized laptops to fit in it, and has many overnights and countless trips to work......Cant find another like it and darn it someday this thing is gonna die......
