This one has a 12" depth. Comes with a spiffy Oddysey 1 RU vent spacer (Ususally sold separately). Heavy-duty nylon exterior with thick padding. Sturdy webbing wrap-around handles plus padded shoulder strap. Zippered top and bottom openings let you access the front and back of your rack without removing it from the bag. It's in excellent condition. No tears. Doesn't smell funky. I just need to go down to a 2-spacer. $70.00 Shipped... Sale must wait until the rackbag I just ordered is on its way.
