The Californian brand Nano Worx, has not been in the market for long but has caught the attention of many fans thanks to a selection of accessories with a strong aerodynamic focus. Now they have just launched a new product that promises to replace the classic saddle bags. It is the Nano Worx Draft Box, a rigid storage compartment designed specifically for the Cervélo S5 (the brand promises that it will be available for more models), which also serves as an aerodynamic fairing.

With dimensions of 32 x 105 mm of opening and a depth ranging from 90 mm on the deepest side to 50 mm on the narrowest side, it offers a capacity of 0.3 liters and a weight of just 100 grams.

The level of detail of this accessory is such that the lid of the Draft Box functions as a tire lever and includes a small space to store a CR2032 battery, like the ones used by SRAM AXS shifters or heart rate monitor straps, for example.
