Rivendell Bike works makes a barsack that may work with your cross levers but I would check the pictures of the mounting rack to decide if you will have enough clearance. http://www.rivbike.com/products/show...barsack/20-208. I am getting this bag for my commuter along with a seat bag as I like the looks and the bags are simple and well made.

The mounting rack for the Arkel Metropolitan bag seems like it gets the bag out farther, so will clear your cross levers better. Its also not a huge bag so you won't overweight it like some of the bigger bags on the market. If my trunk bag is any indication, Arkel makes very well made bags and I would recommend them too. http://www.arkel-od.com/us/all-categ...lebar-bag.html
