0000h I had not noticed that the Blue puts both bosses above the clamp... I can't imagine anyone thinking that there would be enough room for a decent sized water bottle on the small frames.

I took a peek at the Arundel bottles at their website, and I am mighty tempted to get two of those side entry cages; they look mighty nice. But I have to really convince myself, as the Inox cages work rather well and are well made (they just look so dated.)

Maybe they would work well on that Blue.
