I have a Cortech Super 2.0 24-liter tail bag and a Cortech Super 2.0 18-liter magnetic mount tank bag. They are both expandable, the largest bags they offered. The tank bag has backpack straps built in. I used them for one summer and then sold my metal tank Monster a couple of years ago and they have been in a box since. They are in great, as new shape. No rips, marks or tears. All straps/accessories included. The first two pics are my actual bags; the others are from the web. $100 cash for the pair. Over $300 when new. If you are interested, please reply with a phone/text number. Thank you
