From the manufacturer

This bag has a tidy profile and clean lines to complement any bike, from sleek carbon road bikes to full-suspension trail stompers. Don’t let the compact dimensions fool you though! It easily fits one big tube for the MTB or two for the roadie; plus a multitool, levers, and CO₂ cartridge. Quick, secure, and dropper-compatible attachment using a rubber strap by Voilé (included).
