The Silca Mattone Grande can hold up to 3 road tubes and everything you might need on the side of the road or trail.

Use the power of BOA® to keep all your spares in a compact, rattle free pack.

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 .74 of internal volume almost 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!
