Silicone Bellows for Niche Zero and Niche Duo - Near Zero Retention

This custom-made silicone bellows for the Niche Zero and Niche Duo can help you achieve an even lower retention on every grind, most of the time even achieving a 0.0g retention*. It's 100% custom designed in-house and is superior to our previous 3D printed TPU version (discontinued Feb 2023) in terms of texture, flexibility, air-tightness, and durability.

Black is now available as of February 8!

[Design Features]

• The Niche Zero / Niche Duo Bellows complements the grinder's original design rather than replacing any parts and upsetting its visual balance
• Specifically designed to fit into the funnel exactly
• Takes seconds to place into the funnel for use
• Low profile design allows you to close the lid over the Niche Duo / Niche Zero bellows while it's on the funnel
• Fits and works with or without the Niche Zero Flow Control Disk (anti-popcorn disk). Acts as an anti-popcorn device for the Niche Duo
• Prevents popcorning when seated in the Niche Duo during grinding 
• No tools necessary for installation
• No modifications to the grinder needed
• Easy to clean
• Odourless material so it does not impart any smells to your ground coffee

[Variants]

V1.1 

The most current and best version. Has a smooth matte surface that is dust resistant, has accurate shape, and has good wall thickness consistency. Note that some "pieces may come with a very slight oval opening, but will conform nicely when placed into the Niche funnel.

V1.1 - Subpar

These pieces will have a pronounced distorted form, and possibly other surface blemishes, but they otherwise are fully functional. Although some of the openings of the bellows may look far from circular, they will conform when placed into the Niche funnel. For optimal air-tightness on the Niche Duo, the non-subpar version is recommended.

V1.0 - Subpar

There were a few pieces from the very first generation / first batch that turned out below the standard of what we're looking for. We don't like to waste, so we're offering these "subpar" pieces at a highly discounted price. These pieces may have some of the following issues, but not limited to: very thin wall thicknesses of the bellows, bubbles in the bellows, colour blemishes, distorted form, and decreased durability, but they otherwise are fully functional. Although some of the openings of the bellows may not be perfectly circular, they will conform when placed into the Niche funnel. 

The white in this first generation batch is more of an off-white, and may yellow over time, whereas v1.1 is much more white and has a much higher resistance to discolouration over time.
