CASTELLI, Undersaddle Mini Bag

Arrived in new condition, and delivery was faster than originally advertised. The mini fits all essentials, but there's not much room to spare. Fits well under the saddle and looks good.

Less flashy than most saddle bags. Feels extremely secure. More waterproof than it needs to be, so thanks Castelli for taking that into consideration. Tiny interior pocket is good for emergency $$$ storage. Fits a 23c tube, two levers, mid sized multi-tool, and a spoke wrench with plenty of room to spare.

Love this saddle bag. Just big enough for a tube, co2 pump, levers and a micro multi tool. Looks really a sleek on the bike, no movement when riding.

I was looking for a small under the saddle bag and this one is just perfect. in my case I was able to fit a Spare tube, CO2 cartridge, CO2 adapter 2xTire levers, Valve extender, a Multitool and additional battery for my Power Meter. It is tight, but it works perfectly and it does not create the bulk that other saddle bags do.

Fits aero seat post well when other bags couldn't. Tight, but a spare tube, a small tool, one cylinder, two tire tools fits. Well made.

Great quality and fits all you'll really need in case of emergency. simple strap is secure and reliable.

Small and light and perfectly fits 1 road tube, 2 co2 cartridges and small inflator adaptor, levers, micro patch kit with room for small set of keys if needed, This is on a road bike

I should have bought this sooner. It doesn't rattle under the saddle and holds everything I need on the ride. I carry a bike multi-tool, patch kit, two tire levers, multi-tool, and mini-flashlight. Update: the velcro gave out and the bag kept falling off. I frequently ride offroad and easily used this for at least 2k miles.

As I embark on longer weekend rides, it is important to ensure that I keep some basic tools with me in the case of a mechanical/puncture. I have been risking my rides up until now, but finally got myself a worthy saddle bag. Many I have previously come across before seemed to be overly bulky, and I was looking for one which was discreet, compact, and looked good. When I saw that there was a matching saddle bag available, my interest was piqued. The saddle bag itself is very well made. I opted for the smaller model, to keep things as discreet as possible. There is one main compartment which closes with a zipper. Inside there is a separate netted sleeve, to help secure smaller items. The saddle bag has a strap which allows you to mount it very securely under your saddle. It stayed put throughout a recent 87km ride I did. Although a fairly tight fit, I have managed to get the following neatly tucked inside: -Inner tube -CO2 pump -CO2 canisters x2 -Tyre levers x2 -Puncture repair kit -Disposable gloves -Disinfectant wipe The saddle bag is at maximum capacity with the above, so unfortunately there is no room for my multi-tool, which I will have to keep in my jersey pocket. The saddle bag is actually just for weekend rides, as during my commutes I have a backpack with me, and have plenty of storage space there. All-in-all, the Castelli saddle bag is a great buy.

Perfetta per l’indispensabile senza essere panno.

Es passt alles rein (Ersatzschlauch, Multitool, Reifenheber, Pumpenaufsatz, Gas-Kartusche, Adapter Auto auf französisches Ventil) was man im Notfall braucht. Wasserabweisend aber nicht wasserdicht. Sehr kleines Maß, unauffällig aber sicher am Sattel montierbar. Würde ich wieder kaufen.

Calidad Castelli, queda bien fija al sillín, perfecta para llevar los básicos de una bici de carretera… multiherramientas, cámara, desmontables x2, parches, y adaptador de válvula. Saludos

Perfect size for my road bike. It easily fits a repair kit, two CO2 cartridges, and tire levers. I could also fit a spare TPU tube—and even my Crank Brothers multitool.
