a necissary evil
Honestly not a big fan of any saddle bag, but this was a nice compromise. Went with the Small and was pleased at how neatly and securely it tucks directly beneath the saddle. While you should expect a pretty snug fit, the Small should fit a single tube, a C02 cartridge + inflator, and a pair of levers. There's also a clever external pouch on the underside of the straps for your multi-tool, which is especially handy as it grants quick access to this regularly-needed tool without forcing you to dig through the pouch. Bear in mind that if you plan on carrying your phone or any snacks in the pouch, I would recommend getting the Medium size.
