    Great bag for the minimalist

    Light, waterproof and almost invisible under the saddle. Holds one tube, two CO2 cartridges, two tire irons, CO2 pump head and a small wrench. All that is needed for most rides. It sure beats most other larger, heaver bags.

    For holding spares only

    The longish rectangular shape of the bag requires recoiling the spare tube for better fit. I use the Continental Race Light tube as a spare so it takes up less space. Also comfortably fits a tire lever, 16g gas cannister, CO2 inflator, tube patches and a small multi tool. The zip is tight i assume for the water resistance. Its also not possible to unzip the bag whilst attached to the saddle as the strap attachment overlaps the zipline. As per description, this saddle bag is made to hold spares and tucked away.

    This bag carries the essentials needed for a flat fix. It leaves room for my Garmin Radar light on my short seat post.

    Once you go tubeless on a road bike, as in not carrying a spare tube anymore, your old saddle bag is suddenly obsolete and oversized. This bag is perfect for the essentials. I have a CO2 inflator and two 16g cartridges, two tire levers, a minimal multitool, and two variations of tubeless darts, all nicely arranged in this little bag. It sits quietly and is easy to clean. The only downside I've noted is that the velcro on the strap wants to split. I've glued it back down for now, but at this price, I should probably just order a couple more bags and plan on a year each.

    A Great Little Bag

    The Undersaddle Mini Saddle Bag is light, adequately water proof, and just big enough for the essentials a wide road tube, a CO2inflator, some tire levers, and an emergency $5 bill. The size is small enough the bag completely sits underneath and within either side of saddle. I recommend this bag to anyone who wants a reasonably priced, minimalist saddle bag.

    I'm using on my Venge with aero seatpost. It works awesome and it's very small but enough for 1 tub, 1 CO2, a chuck and that's about it

    I hate big, clunky saddle bags......However, there are a few items that every a avid cyclist should carry. Tube, inflato, co2, lever, etc. This bag is made well, looks good on the bike, and simply works.....
