Silca’s nifty Sicuro Capsule attaches to Silca’s Sicuro bottle cage and makes good use of the dead space at the bottom of your frame. Stow some CO2 cartridges, tools, snacks, and more, then close it up with the magnetic lid. We stow it on our gravel bikes and it’s secure, stable, and easy to access.
Basics: Magnetic closure; mesh internal retention; two-bolt mount; works with Silca Sicuro water bottle cage
Pros: Utilizes dead space in your frame for storage; quick and easy to mount; magnetic lid is solid
Cons: Can take up space best used for a second water bottle; tight quarters limits what you can carry

When I attached the Sicuro capsule to my gravel bike during my trip to check out the Big Sugar NWA Gravel race course in Bentonville, Arkansas, I did it partly because I expected it to fail miserably. A magnetic closure? Come on. A few beefy gravel roads should be able to rattle that cover right off.
But the Sicuro’s lid never dropped off, or even came loose. Okay, color me impressed.
The Sicuro capsule attaches to the bottom of Silca’s Sicuro water bottle cage (yes, you have to use Silca’s cage). It’s intended to offer storage space in the dead zone at the bottom of your frame’s triangle, and the Sicuro capsule certainly does that — assuming you actually have dead space at the bottom of your triangle.
As it turned out, I didn’t have as much dead space there as I thought. The Sicuro capsule ended up being large enough to prevent me from attaching a second water bottle cage on my seat tube. In that sense, the Sicuro capsule worked against its intended purpose. But that won’t always be the case, depending on what kind of bike you’re riding and what your storage situation is like. So while it didn’t provide me with the convenience for which it was intended, it’s an ideal solution for anyone looking to squeak in just a bit more storage should that dead space exist.
That said, the Sicuro Capsule comes with a caveat: It’s a tight space inside. I was able to get my multitool, a tubeless puncture tool, a C02 cartridge, and a C02 head in there. It was tight, but it all fit in there. I tried to fit a tube in there, but I could not get a 700x30mm tube to fit in the space, no matter how much cramming I tried. But for the tools I had stowed in there, the space worked nicely. The mesh divider kept everything from bouncing around inside too.
the Sicuro Capsule fits nicely into an arsenal of storage solutions for gravel riders, mountain bikers, and bikepackers looking to maximize storage capacity and minimize dead space. You may end up finding an ideal use for the Sicuro Capsule, though it won’t work for every frame or bike setup. But it’s a low-cost investment should you have the space in your frame for this nifty little pouch, and you’ve got a plan for what you’ll stow in it. Suffice it to say that security won’t be an issue; after experiencing some high-speed, molar-rattling descents in Bentonville, the Sicuro Capsule lived up to its name.
