This is the original Ventura Bike-Pack System and consists of a vertical Pack-Rack. This Pack-Rack supports the various packs that we make to suit. With the Aero System a number of the packs can be zipped together to dramatically increase usability and capacity. For example, the Mistral and Bora can be zipped together or two Mistrals or two Boras. The same applies with the Aero-Spada and the Aero-Delta.
