FAQ

What is the difference between the SILCA Mattone Grande and the standard Mattone?

The SILCA Mattone Grande holds 0.74L, almost twice the volume of the original Mattone. It carries up to three road tubes, two CO2 cartridges, two tire levers, and a multitool, or two 29x2.5 inch MTB tubes with kit. Both bags use the same BOA Closure System and build quality, so the choice comes down to how much you need to carry.

Does the SILCA Mattone Grande rattle under the saddle?

No. The SILCA Mattone Grande uses a BOA ratcheting dial that holds the bag tight against the saddle rails with more than 15 times the force of Velcro and will not creep loose under vibration. It stays silent and secure on rough roads and trail.

Is the SILCA Mattone Grande waterproof?

The SILCA Mattone Grande uses a YKK waterproof zipper and a weather-resistant shell that sheds rain and road spray. It is built to keep tubes and tools dry in wet riding, though it is water resistant rather than rated for full submersion.

Best For

Cyclists doing long road rides, gravel events, or bikepacking routes where carrying two or three tubes is smart preparation. It is also the right pick for mountain bikers who need extra tube volume without resorting to a full frame bag.
