Large Capacity:With capacities of 1.7L and 1.3L (dimensions: 24 x 10 x 8.2 cm and 22 x 9.5 x 8.2 cm), the bag offers ample space for a wallet, smartphone, tools, and more. Side mesh pockets are ideal for securely storing small items. Perfect for smartphones up to 6.8 inches, such as iPhones or Samsung Galaxy phones.

Highly Sensitive Touchscreen:The TPU film allows for easy touchscreen operation on the go. Velcro closures keep your smartphone secure, and the hidden headphone port allows you to take calls and listen to music while driving.

Durable 3D EVA Hard Shell:Made of durable EVA using a 5D die-casting process, the bag's hard shell provides a stable shape that won't easily deform. The outer carbon fiber surface is particularly abrasion-resistant and durable. Waterproof: Thanks to its polyester fabric and seamless, double-sealed zippers, the ROCKBROS frame bag is water-repellent. The robust construction also protects against impacts. Note: Not suitable for continuous use in heavy rain or complete immersion in water. Note: Both versions (1.3L and 1.7L) come with a rain cover. Easy Installation: Easily and securely attaches to the bicycle frame thanks to the 5-point Velcro strap. Adjustable straps fit most bicycle types and ensure stability, even on uneven terrain.
