Here is something that I clever and helpful when that time is needed. The Handle Pub nub is a bottle open that is attached at the ends of the handle bars. It’s simple yet helpful. Made from rubber, aluminium and steel. It is small that it it does not add any additional length or bulk. Available now at uncommongoods.
This a is a great item on the go. It is helpful and can be a lifesaver in the hot summer days when needing a bottle opener. I might get one!
