Shimano AX aero bottles

[Taul Paul]

Hello
Can anyone tell why these bottles are slightly different. They both look
like proper Shim bottles but have sight differences.
Which one should I keep, I only need one so one will be for sale with cage.
Thanks

Not 100% sure but the one without the aero cap is Adamas AX.

Might be simpler for me to be told which one to keep for my 600AX groupo.
The one with the AX on it or the one without the AX on it.

THE ONE WITH THE AX .......ON IT

Sell the cheaper one off.

The aero bottle is a bit of a faf about in using it! ...Flip off the aero cover - ensure the aero cover is out the way - pull bottle out of cage and again in reverse order :facepalm:
