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 my previous 3D printed TPU version in terms of texture, flexibility, air-tightness, and durability.
For a long, in-depth look at the bellows in action check out the video:
Simplicity and maximum effectiveness are my design goals, and both are carefully infused in my bellows' design
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 Flow Control Disk (anti popcorn disk) for Niche Zero. (No Flow Control Disk for Niche Duo)
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

Batch 2 - Production (Available)
The latest version of my bellows, made by silicone compression molding. Smooth matte surface that is dust resistant, has accurate shape, and has good wall thickness consistency.
Batch 2 - Limited Matte (Available)
These pieces are the same as the final production spec except they do not have a final surface treatment. They are fully matte and soft to the touch, but they also tend to attract dust and coffee grounds easily.
Black Limited Matte now is sold out.
Batch 1 - "Subpar" (Available)
There were a few pieces from the 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 "reshape" nicely when placed into the Niche Zero funnel.
- Niche Zero
- Niche Duo (Requires light press fit into funnel hole)
- Grinding after changing grind size or using darker roasts/oilier beans may increase retention.
Achieve the best results with lighter roasted beans and at a consistent grind size setting.
