SILCA Mattone Bike Saddle Bag - .5L Capacity - Compact Under Seat Bicycle Bag for Road, Gravel, and Mountain Bikes - Easy to Access, Secure, and Durable - BOA Closure & Waterproof Zipper

Great and compact under-seat bag that holds a lot! Fits a standard 700c spare, CO2 cartridge w/ adapter, Crank Bros M17, Dynaplug Racer, and two tire levers. Quite a bit for such a small form! It's not completely waterproof, so if you take it on a wet ride, don't forget to remove anything that might rust or get ruined and dry it all out. Great zipper, BOA is money, bag sits tight and secure. Would buy again.

Favorite saddle bag, this is my second for my second bike. A little pricey but they last, work great, and are easy use. Had a friend buy a no name brand, saved a couple bucks, but lost $50 in tools and gear when it opened during a ride. I have never had an issue with this bag. When I get a third bike, I will get another of this bag.

nice compact size, well built, holds well onto bike.

I really hate long drawn out reviews. I recently purchased a Specialized S Works, Tarmac with bolt in axles. I did not want to damage below the dropouts when removing the front wheel for a flat repair the bicycle must be inverted to service it in the field. The problem with this was with a traditional seat bag you need to remember to grab all the items for the repair prior to turning the bike over as it makes it very difficult to retrieve them. The silica bag appeared perfect when the bike is inverted. You can open the pack and look directly into the pouch at all your tools. You can then retrieve tools as you need them and quickly return the items back to the Silica bag when completing the repair. I especially liked the high contrast red interior, which made it very easy to view my items. I purchased the larger of the two versions and was surprised at how many items it held. You can definitely fit at least two butyl 700x23 inner tubes, two tire levers, two co2 with full size tire inflator, and a multi tool with room to spare. If you still like to carry your items in a seat bag, I would definitely consider one of the silica bags.

I was conflicted by all of the reviews on the two sizes of this bag, so I ordered them both. They run a 700 x 30 tire. My current set up is tubeless, but I need to carry a tube just in case. When I attempted to put my 30 MM tube into the smaller size, it basically took up 90% of the space. There is no way on earth. Anybody is putting a larger tube in that small pack and putting much else in there. I just want you to be aware when you see the demonstrations and people talking about tubes, just assume most people are running smaller tubes probably 23 or 25 mm. The good news is that the larger pack is not really that big. I was able to put my tube, two CO2 cartridges, multi tool, tire, levers, and a few other things. It is very compact and sit nicely up under the seat. Sitting high under the sea, it was my other requirement for a new bag. I have been using a Garmin Varia radar detector off my seat post, and so many of the bags tend to fall down or slide down on top of it. This bag is extremely compact, and really fits and locks and placed nicely. I would highly recommend it, but just beware of the size as I think it’s a little misleading, and thus, the four stars.

Great bag with an ideal size, secured by a solid BOA dial, offering just enough room for essentials. The locking system is simple to install and stays snug against the saddle without any wobbling or shifting. Additionally, this bag looks great! Keep in mind, you'll need to remove the entire bag to access the zipper and contents, but since frequent access isn't expected (hopefully), this isn't a major issue.

Another amazing from Silca!!!

It's a great fit on the back of your seat, depending on how you position your seat on the seatpost. If your seat is further forward, it's more of a hassle getting it on. Other than that, it's great to have. It has lots of space to pack more than you need for a normal ride. The straps and material are durable. If you're going to wash it, take everything out first, especially if you're keeping electronics in there.

Ajuste e ótimo, não fica balançando. Porém antes de comprar saiba que é bem pequena. Vai bem uma espátula, uma câmara reserva e CO2 apenas.

I think this is a great item. It looks good and fits snugly and securely under the saddle. Despite being compact, it holds an impressive amount: a multitool, dedicated tyre-breaker, chain links, puncture repair kit, wound wipe and Elastoplasts, a penknife, emergency ID card and tyre levers — and there’s still a little room left for something extra.

This is a great saddle bag. It fits a lot, it’s snug, and it attaches to the rails without rocking back-n-forth. It looks sleek too!

Molto compatta, non sporge dalla sella e sono riuscito a farci stare una camera 28x2,0, due leva copertoni, un kit di pezze adesive, una bomboletta di CO2 ed un paio di guanti leggeri. La chiusura con zip, il tessuto di cui è composta e l’aggancio, comodo con il sistema Boa, dopo un anno che la uso sono ancora integri.

Rewelacyjna torba podsiodłowa, mała ale pojemna, świetne mocowanie, być nie goni. Idealna do droppera.
