Last week I ordered and received the Topeak Explorer Rack and MTX Trunk Bag from Amazon and absolutely love them!
The rack is secure and the trunk bag is so much better than the flimsy ones I've owned in the past.

The ability to just slide the bag off the rack and carry it with me is awesome! No straps, cords or anything like that to unbuckle.

I especially like the fact that the bag sides are stiff and don't droop or sag.

I enjoy photography while cycling and this setup is perfect for carrying my camera, cell phone, snacks etc...

Highly recommend!

Any other Topeak fans??
