I bought the Topeak system for my upright a few years ago and really like it. The track system makes removal of the bag a breeze which is perfect since I tend to trail my bike on top of my truck. Its well insulated so an ice pack will keep food or beverages cold for hours. The fold out panniers are great when you want to carry a jacket in the morning only to shed it in the mid day and not stuff it in with your beer/food. The lid has a small zippered compartment to store pens, tire pressure gauge, small flashlight, etc. With the new recumbent having disc brakes I was sure I'd have to retrofit the rack somehow. While looking at Topeak's site, I found they made the Explorer rack for disc brake bikes. I just installed it on my Volea and it fits great. BTW, Amazon has the best prices on both.
