After my bicycle saddle inclusive seatpost and even the Klickfix adapter was stolen, this bag was the cheapest way to get a spare mount for me. The big brother to this is simply top, a real small space miracle! But if you really want to take only times a small pocket for the patch tool, and is still looking for cell phone and keys, this bag is just right. Point deduction's me that you can not buy affordable replacement holder in case of loss.
