The Zone3 Top Tube or 'Bento' Box, as they are better known, is designed to store all your training or race essentials within an easy access area while keeping in line with your bike’s aerodynamic profile to help minimise any drag.
This storage device fastens to the top tube and around the stem with four hook and loop straps to give a neat and secure fit to the frame. It is very quick and easy to install.
The bag is made from a water-resistant material and this is further aided by a premium waterproof zipper. The zip puller is big enough to allow easy entry and closure even if wearing gloves.
The size allows for storage of nutrition, spares or personal devices and is perfect for training or racing. There are also reflective logos printed on both sides for better visibility.
