Alloy washer bottle cap..?

[Peloton]

Anyone know where I can get one of these, if it's even possible to get one? It's the only cap that's not alloy and it's annoying me (for some reason).

Does that fit? It looks the wrong shape.

Not 100%, might be worth giving them a call to double check. I've spoken to them a few times and they know there stuff.

I might just do that. Cheers
