Silca Seat Capsule Premio is the saddle bag option for those that prefer more structure and internal volume than what a seat roll has to offer. A high-strength thermoformed shell creates a modular structure with two internal dividers that help keep everything organized. The capsule is secured to the bike using the BOA Closure System, and features Rail Guard for superior grip and protection of the saddle rails. The zipper is a YKK locking model that bisects the lower third of the bag. Our designer chose this low position to make it easier to access the bag while it’s still attached to the saddle; a key difference between a seat bag and a seat roll.
