    Meaning Brick, in Italian, the Mattone is SILCA's award winning seat bag powered by the Boa Closure System.

    With the new Mattone Grande, we have now created a 'bigger brick' with .74L of internal volume almosn 2x the volume of the original Mattone (0.41L). The Mattone Grande is capable of holding up to 3 road tubes along with 2 CO2 cartridges, 2 tire levers and a multi-tool.  It can also easily hold up to two 29x2.5 MTB tubes along with CO2, levers and Multi-tool, the Mattone Grande is ideal for those long adventure rides or races where you must be prepared for everything.  

    Similar to the original Mattone, a high friction Hypalon strap with BOA® Closure completes the package.  Making more than 15x the power of Velcro®, the BOA® Closure uses a ratcheting mechanism that will not creep or loosen even under the most extreme vibration and impact.  This ensures the Mattone will remain ‘high and tight’ under your saddle until you need to access it... no swinging, swaying, or rattling... ever!

      Perfect size, perfect fit!

      I fitted a Mattone Grande to my gravel bike and I absolutely love it.

      Spacious enough without being bulky, and the BOA system keeps everything in its place and rattle free, and the most important thing is it looks amazing and complementes the look of the bike.

      Definitely a keeper!

      Best saddle bag...

      Love the way it tucks up under the seat and no rattling whatsoever!

      Now that I purchased an Impero Ultimate II pump I really don't even

      need a bag this big as I only carry a TPU tube, patch kit, mini multi tool,

      tire levers, tire boot and presta/schraeder adapter.

      Nice Pack but...

      I bought this pack because I needed one that did not interfere with the dropper post on my eMTB. I have 29x2.5 tires. I run tubeless and carry a spare tube, 3 CO2 cartridges with head, tire levers, a small multi-tool, bacon strips, master link, and a spare derailleur hanger. Unfortunately, this pack will not carry what I need. I was left with 2 alternatives; reduce what I carry or buy a Tubolito spare tube. I bought the Tubolito and it worked. I have not tried this on a trail but the under-seat fit was easy. I wish there was a small strip on the pack to clip on a light. The photos show what I wanted to carry and what I couldn't carry.

      Inner tubes can be a tricky beast. They range from some of the thickest and heaviest available, all the way down to the smallest TPU tubes. We have seen customers fit anything from multiple TPU tubes all the way to just a single inner tube that is much larger.
