This is the bicycle capsule. I have been searching for ideas and storage is not a very common accessory. The best thing about the capsule is that it is not bulky, you can attach more than one if you need to carry first aid supplies or a basic tube repair kit. It looks great and serves a function. The best part is that it is yours to take for free, enjoy! ( More bicycle frame tube sizes will be available in the future) - Marcos Quezada (Owner and Operator of Venom Engineering)
