ROCKBROS Road-to-Sky Bike Frame Bag

The bag features a streamlined, slim profile designed specifically to sit flush against the top tube. Most riders find it stays well clear of their legs, though fit can vary slightly depending on your bike's geometry and your pedaling style.

An IP67 rating means the bag is fully protected against dust and can withstand immersion in water up to one meter deep for 30 minutes. In practical terms, your phone, keys, and snacks will stay completely dry even during heavy downpours or muddy trail rides.

It uses a reliable strap-based mounting system designed for the top tube. Once tightened, the bag remains stable and won't sway or shift, even when you are riding over rough terrain or standing up to climb.

Yes, the 1L capacity is spacious enough to hold most standard-sized smartphones alongside other small essentials like a multi-tool, energy gels, or keys. If you have an exceptionally large 'Max' or 'Plus' sized phone, you may want to measure your device against the bag's dimensions first.

The zipper is engineered to be impermeable to keep water out, which can make it feel slightly stiffer than a standard zipper. It is designed for durability and weather protection, so it may require a firm pull to open, especially when the bag is fully packed.
