    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!

      Great bag with some flaws

      I have 2 of the smaller versions of this bag, for my road bikes. I bought this one for my gravel bike. Great capacity and looks good as well. I'm a fan of the BOA clasp. However having used this on a number of wet/muddy gravel rides I notice the bag does leak somewhat and even in dry gravel conditions I've notice quite a lot of dust getting in. TBF this was worse under the extreme conditions of the last two Unbound events. Most frustrating I've found is over time the zip becomes quite stiff, even after cleaning and in wet events does get clogged with mud etc.

      The perfect saddle bag

      This saddle bag is the perfect all-rounder for training or exploring rides. The Mattone Grande is not for those that are looking for the bare essentials in a saddle bag. Very secure with the BOA system. And, most importantly, loads of room to bring the gear/ tools to support your ride of choice.
