Brompton Metro Messenger with Frame, Black, 23L Since I don't plan to use it, I'd like to pass it on to someone who will cherish it. With its large capacity, how about using it as a travel bag for when you're using a train with your bike? A well-balanced messenger bag perfect for everyday use. The back pocket is designed to hold a bottle. Inside, there's a padded compartment for a laptop and a pen holder, making it ideal for business use. It's a functional bag with a simple design. Comes with a waterproof cover. Size: W400 x H300 x D150 (mm) Capacity: 23L Frame: Detachable frame Compatible models: Attaches to all handlebar types
