FS: Topeak MTX trunk bag EX-for use with a Topeak QR Beam rack system. (Rack is not included.) The bottom of the bag slides on the rack's runner and snaps in place.

Dimensions are 14" L (including release tab) X 6.5" W X & 7" H. It has a large main compartment with an inner pocket, zippered mesh side pockets and bungee on top. Reflective strip in rear. It can be hand-carried with the sturdy handles-or use the shoulder strap. Excellent condition.

I've upgraded to a larger version with panniers and no longer need this bag. $35 -including shipping.
