If you’re a commuter or city rider and you must constantly bring things with you, then you might benefit from the Bontrager Interchange City Sling Handlebar Bag. Instead of carrying it on your back or over your shoulder, the bag fits on your handlebars so you can still move freely. It installs and uninstalls fast with the interchange handlebar bracket. There’s also an easy-access tricot-lined sunglasses pocket. It also helps you keep your stuff organized with internal dividers and pockets. You can purchase the Bontrager Interchange City Sling Handlebar Bag at the Trek online shop for $69.99.
