The B-RAD TekLite Roll-Top Bag is a premium, lightweight, and flexible storage option to keep your riding essentials protected from the elements. This follows the same profile as the original B-RAD Roll-Top Bag, but uses the new TekLite material, which is made with layers of strong, durable, and lightweight fibers.Bags are just the right size to carry your wallet, snacks, keys or tools, yet sleek enough to stay out of the way of legs while riding. The roll-top opening makes for quick access, while the hook-and-loop strap allows for easy removal and repositioning. It can be attached under a saddle, strapped to a frame, secured in a bottle cage, or mounted onto any B-RAD Base.1.0L capacity to carry riding essentials: multi-tools, spare tube, or snacksUltra-high-molecular-weight polyethylene (UHMWPE) material is lightweight, strong, and durableRoll-top design protects contents from water, dirt, and other road gritSilicone-backed strap with hook-and-loop design keeps bag securely in placeFlexible, durable construction from a composite of abrasion-resistant, high-tenacity fibersCOMPATIBILITYCan be mounted directly to any tube on a bike with just the strap.
