When you're riding, you don't want to think about your pack—and the medium-volume Syncro 12's streamlined profile ensures that you won't. With an included updated Hydraulics LT 2.5-liter reservoir, ventilated AirSpeed™ suspension and included raincover, this bike pack is the perfect option for longer rides in desert heat or humid climates, with space enough for additional on-bike essentials like tubes, first aid, and more.
