If you are a hard core commuter who lives by the mantra, if I just had a bit more room, the Super Metro is your bag. Two inches longer and one inch wider than the Metro Basket, it also has internal suspension webbing to support heavy loads, but we increased the structural support with 6061 T6 aluminum tubing at the hinge point and the outer edge of the bottom of the bag. The bag is topped off with an 11 mesh sleeve that will nearly double your gear hoarding capacity. For added stability we used our cam suspension with adjustable top hooks so you can position the bag well off the back of the rack. There are also two internal flat zipper pockets so you can stash your keys or the optional rain cover. One word of warning, if you plan to fully load a Super Metro or worse, a pair of them you better have a well made rack.
