Tool cases are a great relief to the pockets of cycling jersey, which especially in the summer do not like to be heavily loaded - at this time of the year we especially appreciate the lightweight of our cycling outfit. The tool case will fit perfectly the bottle cage, leaving the space in our pockets for telephone and food. The cycling tool case can fit such equipment as a spare inner tube, the multitool, tire spoons, as well as money and keys to the house or additional gels and energy bars. Tool case leaves space only for one water bottle on our bike, but when cycling in the urban areas buying water or other drink should not be a problem. We definitely recommend this way of transporting all kind of accessories.
