Silca Mattone Grande Saddle Bag

The Silca Mattone Grande Saddle Bag is a high‑capacity, low‑profile storage solution designed to sit securely beneath your saddle and hold essential cycling spares and tools. Named Mattone (Italian for “brick”), this “bigger brick” version offers nearly twice the internal volume of the original Mattone, making it ideal for adventure rides, long gravel outings, and races where you want extra room for tubes, tools, and accessories.

A signature feature of the Mattone Grande is its BOA® Closure System paired with a Hypalon strap. The ratcheting BOA closure generates consistent tension that resists loosening under vibration and impact, keeping the bag firmly in place without rattling or shifting. The exterior uses a water‑resistant YKK zipper, while the construction materials are designed to balance durability and everyday usability.

Build & Features

The Mattone Grande’s structured body and thoughtful shape help it fit snugly under most saddle rails without interfering with pedaling or dragging on rough ground. The BOA closure system replaces traditional hook‑and‑loop straps, offering a more reliable and fatigue‑resistant attachment that stays “high and tight” even in challenging conditions. The water‑resistant zipper and robust materials make this bag suited for all‑weather riding.

The capacity and dimensions make the Mattone Grande a flexible option for riders who want more than the bare minimum: it can carry standard road or larger tubeless tubes along with tools and inflators, or be used as general storage for snacks, multitools, patch kits, and other essentials on longer rides.
