Acier Test Ambassador Info

Thank you so much for your time, invaluable input, and trying Acier! You have been selected for your expertise, passion for cycling and products, detail-oriented nature, and trustworthiness.  

Please sign this waiver before riding with the bottle.

Your bottle is a prototype and we are continuing to make improvements.

Please test the bottle on different bikes and terrain, Zwifting, at the gym, in the car, etc. Even if it's not hot outside yet, we'd like Acier to become your go-to bottle.  

Please note:

  • Do not use with hot liquids! Luke-warm liquids should be ok, but if there's anything hot, it will create pressure and the cap or nozzle may blow off.

  • Inner cap is not dishwasher safe as there is a silicone valve that may become dislodged. All other parts are dishwasher safe.

  • The cap can be disassembled for thorough cleaning, as shown below.

  • The inner cap screws off from the underside. When reassembling, loosely seat the gasket after screwing the inner cap into the outer cap. Screw the body on to seal the gasket. 

If you are ready to give feedback (the sooner the better), please fill out our survey.

If you have any questions or immediate feedback, please send an email

Thank you so much again and happy riding!
