I secure the one under the down tube with a toe strap.
In 1l sizes , I've found the lids to be the weak point. They are no more robust than the small sized bottles. If you drop a full one and in lands on the top of the spout, it punches the nozzle clean through destroying it. For this reason, I use one 750 and decant from the others to it, carefully. So, if I was off on a big tour, I'd use a cage that takes more regular hiking bottles. I've got a BBB XL, but you can't seem to source them any more.
I have the BBB XL, but it's just too large on the down tube - Is there room for your BBB XL down there?
Also what is the exact cage you have on the down tube? Is it stainless?
