The SILCA Asymmetrico saddle bag uses everything that was learned in 5 years in the production of the award-winning Seat Roll Premio. It is smaller, lighter, more abrasion-resistant and has an additional pocket. Thanks to the patented BOA® locking system, the bag can be easily, quickly and safely attached to the seat stays. The bag has four pockets inside for a Co2 pump, tire lever, tube and tools. In addition, the practical rail guard protects the seat stays and offers the best possible fixation of the bag.
