With more than 2x the volume of the original Mattone, Silca&&';;s "bigger brick" features everything we love about the Mattone, upsized for those long adventure rides or races where you must be prepared for everything. 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. Just like the original Mattone, a high friction Hypalon strap with BOAA(R) Closure completes the package. The BOAA(R) Closure ensures the Mattone Grande will remain 'high and tight&&';; under your saddle until you need to access it... no swinging, swaying, or rattling... ever!
