Go from bike to the office in one easy move with Bontrager's Town Briefcase. The Transit hooks and lower hook-and-loop strap secure the bag to most rear racks. When not on the bike, you've got a shoulder strap that stows away when not in use. Clever details like the 15-inch laptop sleeve, external helmet carry, and reflective accents make this bag a utilitarian's dream.
