Although you won't see Team Garmin-Sharp-Barracuda riding with the Arundel Uno Seatbag on race-day, when the support cars are in the garage, its an unmistakable accessory on their saddles -- and for good reason.
The Uno is just large enough to carry the bare essentials -- a tube, levers, CO2, and some fun/emergency money. And if Arundel's bottle cages are any sign of its quality, you can be assured that you're getting a feather-light, beautifully constructed transport for your essentials. For security, the Uno attaches to the saddle rails with Velcro, and to prevent the seatpost clamp from damaging the bag, Arundel added a leather patch to its top. It has an internal capacity of around 16 cubic inches, and uses a double-stitch construction to ensure years of quiet service.
The Arundel Uno Seatbag is available in the colors Blue, Black, Grey, Pink, Red, and Yellow and in one size.
I did a ton of research on seat bags. I have no life. After putting way too much time and thought into something as simple as a seat bag, I decided to go with this small, simple and clean bag. I guess some of the photos were a little misleading as to the petite size of this thing, but man it's tiny! The nice thing is, you can still pack quite a bit to help you get home in case of a flat. One of the main reasons I took so long to pull the trigger on a bag is because I know they are generally shunned as being ugly and stupid...but they still serve a very important purpose! Often times I'm riding before I work the evening shift and I will go for 20+ miles away from home during the middle of the day when most people are at work, that means if I get a flat, I'm stranded.
I have this stuffed with 1 tube, tube patches, a Pedro tire lever (pretty bulky), a 6 tool mini-tool, 1 x Co2 cartridge and Planet Bikes Co2 chuck (The one with that big red knob which is obnoxiously huge! Don't buy it). It all fits rather well and still zips just fine.
I ended up also purchasing the Arundel Dual from Competitive Cyclist because I ride some rough roads, dirty trails, and generally have bad luck. This will hold 2 tubes and Co2 cartridges plus a larger multi tool which gives me enough confidence to ride harder and farther before I have to go to work.
Arundel has become known for their impeccable attention to detail, and ability to perfect otherwise largely overlooked accessories like bottle cages, bar tape, and saddle bags. The Arundel Uno is yet another perfect example of this perfection. Just big enough for your 700c tube, 2 CO2's, a lever, a folded up dollar, and a microinflator, this bag sits tucked neatly up under most any saddle. It certainly is snug, but works great.
Don't buy it if you like to keep extra's items like your keys, wallet, or food in your saddle bag. Do buy it if you want a saddle back that will free up your jersey pockets and are comfortable exploring the road with the bare essentials.
I love this seatbag because of its compact size. It doesn't swing around the saddle like my other ones have. i carry my co2 in my jersey pocket so this is all i really need to carry my spare tube, park tool levers, and a small multi tool. that is really all you can fit in this bag. if you want more room, i would recommend the arundel dual instead.
Perfect little seat bag. Very well made. Hold 1 tube, glueless patches, tire boot, true levers, chain tool and small multi tool.
I have one on each of my road bikes.
Long term durability may not be the best though: I had one that was starting to get cut after 1 year of use and the velcro got weak enough that I lost the bag.
