I don't think you would even have space for a water bottle with a tangle bag attached. I've a Jandd frame pack on an 18" frame and my bottle still touches the bottom of it. Check everything twice with a tape measure before you buy anything.
That's what my question about, is Tangle Bag really worth of buying if bottles won't fit (at least on small frames). I don't know how Ogre bag will work near chainrings but will probably try it on. The Ogre bag is 25 cu inch bigger - it always help to have an extra room for spare tube.
Thanks for reply
