Bellows Upgrade for Breville / Sage Barista Touch Impress - Near Zero Retention

If you're a single doser, this bellows upgrade can help you achieve 0.0g to 0.2g retention on every grind*. This 3D printed flexible part fits in between your machine's stock hopper and stock lid and transforms it into a blower, so you can say goodbye to the usual varying retention of 0.2 - 0.5 grams of coffee. [Design Features] Simplicity and maximum effectiveness are our design goals, and both are carefully infused in our bellows' design. The bellows complements the grinder's original design rather than replacing it and upsetting its visual balance Super easy installation takes less than a minute No tools necessary for installation No warranty-voiding modifications needed Zero contact between bellows and beans each time you dose Small manual included with assembly instructions and best use tips For the technical users, it displaces approximately 185mL of air per pump Bellows works even if you prefer to store beans in the hopper (though less effectively) [Compatibility] This bellows is compatible with: Breville Barista Touch Impress (BES881) Sage Barista Touch Impress (BES881) This bellows is also compatible with: Breville Oracle (BES980) Breville Oracle Touch (BES990) Sage Oracle (BES980) Sage Oracle Touch (BES990) [Additional Notes] The bellows will add an additional 2.7cm (1-1/16in) to the height of your hopper after installation, but you need additional space above it. Measuring from the top of your lid without the bellows, you need about 9-13cm (3-1/2 ~ 5-1/8in) of clearance space to operate it comfortably. [Optional Grinder Seal] Add a seal to help you prevent buildup of beans and grounds in the groove around the outer burr. If you've used your Breville / Sage grinder for a while, you'll notice that some coffee beans eventually get lost there, and can be especially frustrating for single dosing. Installing this flexible silicone seal will prevent any major buildup and greatly decrease your overall long-term retention of beans. Include this seal in this bellows order for a combo discount.
