Always within reach, the minimalist lightweight zipper bag holds a tube, money, and keys. It features a Velcro closure to secure the bag to the saddle rails. There is a mount for a flashing light, reflective 3M prints, and a durable, washable outer material on the bottom. Note: Sand, dust, and improperly packed bags can cause the paint at contact points to become dull or scratched over time. To avoid these abrasion spots, you can protect your frame or rack with foam elements or protective films before attaching the bag.
