SILCA releases MATTONE GRANDE with room for more, more than twice more

Indianapolis - 7 December 2021 - SILCA today is launching the bigger version of their award winning MATTONE seat bag with the BOA® Closure System, the MATTONE GRANDE. Mattone means brick in Italian and packs all the gear you need for three flat tires, a multi-tool, cleaning cloth and a wallet for your coffee breaks.

With the new MATTONE GRANDE, SILCA has created a ‘bigger brick’ with 77 cm3 of internal volume more than 2x the volume of the original MATTONE (36 cm3). 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 doesn't 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!
