WATER BOTTLE HIDING DESIGN: Installing it on a frame larger than 54 yards will hardly affect the access to the water bottle (620ML).
Noted: If you need to install the frame bag and two water bottles at the same time, the best choice is to use a road bike frame of size 54 (M) or above, because each brand's road model and frame geometry may be different (this frame bag is not suitable for most mountain bike frames).
The zipper on one side is a shallow pocket where you can put your cell phone, ID, etc. The other side has a deep zipper pocket for clothes, etc. There are three net pockets inside the zipper, which can hold inner tubes, tire levers and other tools. The top of the inner compartment is designed with a portable air pump fixing position, which is fixed with an elastic band. The bottom of the bag has an elastic rope, which can be used to tie up small items.
The front of the bag is designed with a hidden opening for the use of power bank data cables and the bottom is equipped with an elastic rope to fix the air pump and repair tools.
