Hey, OP.
Did you end up getting a bottle?
I'm currently looking to replace my plastic cycling bottles with stainless steel or titanium, but where my default would be Klean Kanteen (yes, American, but their values are second to none), it's hard to find high-quality, lightweight (for cycling!) bottles around.
I'm almost tempted to buy titanium bottles from Aliexpress and call it a day.
I've heard of people complain that steel bottles that use steel tops "scrape" together when you are using the lids, and that can cause metal particles to shed into the water.
That's one of the reasons why most steel bottles have plastic lids.
