Topeak's little Tri-Bag is designed to fit on your tube and around your stem. Its true purpose is to hold racing and training essentials usch as energy bars and gels. That said, there's no reason why you can't use this bag in a more practical way too, such as to stash a tube, mobile phone or multitool if required.
In conclusion...
Handy, all weather frame bag for all your bits.
