Topeak Fork Drybag Description: The Topeak Fork Drybag is a compact and lightweight bag designed to carry and protect the gear needed to support epic cycling adventures. This roll-top style bag is made out of a lightweight and rugged TPU material that will house and protect the contents from the weather. An integrated air release valve enables purging of excess air from a loaded bag so it will have a lower profile, preventing this bag from getting caught on overhanging trail obstacles and improving the security of contents inside throughout the ride so it won't shift around and make a bunch of noise. Finally, this bag has a few options for mounting to the fork of a bike, making it much easier to add cargo carrying versatility to any bike.
