I've got the Stanley Adventure mug, only 230ml, but fits perfectly in a standard cage. Fairly cheap too and ideal for keeping a coffee warm on the way to work.
Ah, I think that looks like what I need. I don't want to have to bend the bottle cage as I also want to use normal bottles without having to bend and re-bend every time. is the Stanley one plastic on the outside?
