This framebag from Revelate Designs is great if you don't want to fill up the entire front triangle with a bag, saving some space for water bottle cages. Here's what Revelate have to say about it:
2015 updates: Interior pump mount straps, additional padding, secondary divider in left pocket and premium coated webbing attachments.
Tangle™ bags are rectangular-shaped half frame bags. They can be used for everyday riding & commuting, or any adventure big and small.
The main compartment features an exit port for a hydration tube or battery wire, a zippered flat left side pocket holds smaller stuff. Attachment is made with reinforced velcro along the top tube, other mounts are adjustiable with webbing and low profile camlock buckles with strap keepers. All attachment points bartacked for strength.
Tangle's usually leave room for both water bottle mounts. To check, measure the vertical height from the top of the bottle to the top tube and compare with bag height. In some cases you may need to use side entering cages or smaller bottles.
