Purchased for a non support ride and it held everything I needed. The 3L is a little short for a 56cm frame would recommend sizing up to the 4.5L.

About as simple as it gets but it is done well. We'll see how long the zippers hold up. The only knock I have with it is the head & down tube buckles. They poke out a bit and don't hold as tight as I would have like. Velcro would have been preferred. I also wouldn't call it fully waterproof but the material sheds a rain shower surprisingly well
