specialized awol front rack "pizza rack"

Do you need a net or some flexible bungee? If the latter, then Blue Lug X-straps are nice bike sized, but Japan, shipping, etc, may make that too expensive.

I'm not sure a cargo net is the best solutions for a pizza rack.
in my experience, cargo nets are useful if you've got a basket but otherwise aren't really that practical.
obviously depends on what you're carrying, but I've found that adjustable straps or double sided hook and loop tape cut to appropriate lengths work well for most stuff.

Would these fit the bill?
