We got back from Interbike with our Catrike bags for the 700 and Trail, eager to slap them on and see how they look.
Well... they look just like bags custom made to fit a trike. From the front of the trike, they're nearly invisible, and they fit the space frame nook perfectly.
Installation is quite simple, using a series of perfectly placed velcro straps. The Catrike Trail bags also come with a horizontal bar that keeps the bags from swinging inwards towards the rear wheel.
Please pay no attention to the fact that the seat on the Catrike Trail is way off center. Oh crap. Now you're going to pay attention, aren't you?
