Silca Seat Capsule Premio

The BOA system uses a dial-tensioned cable to pull the bag tightly against your saddle rails, creating a much more secure, rattle-free fit than velcro. It also eliminates the abrasive straps that can rub against and eventually damage your cycling shorts.

The Seat Capsule Premio is designed to fit most standard rail saddles. Because it uses a flexible BOA cable system, it adapts well to different rail widths, though it may not fit saddles with non-standard or integrated rail designs.

With 625cc of internal volume, it is sized perfectly for the essentials: a tube, CO2 inflator, tire levers, and a multi-tool. It is ideal for road or gravel riders who prefer a compact, organized kit over a bulky saddle bag.

The two modular dividers allow you to create distinct compartments, preventing your tools from rattling against your spare tube or CO2 cartridges. This keeps your gear silent while riding and makes it easier to grab exactly what you need during a roadside repair.

The structured shell actually makes packing easier because the bag holds its shape, allowing you to slide items in without the bag collapsing. It provides a consistent, predictable space that is much easier to manage than a soft, unstructured seat roll.
