Silicone Bellows Upgrade for Breville / Sage Smart Grinder Pro - 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 flexible silicone bellows 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. The silicone version is completely designed in-house and is superior in flexibility, durability, and air tightness, allowing for a more effective clearing of retention per pump compared to our previous 3D printed version (discontinued August 2024).

[News]

The evolved silicone version of this bellows is now available! Pre-orders will be shipped first, starting August 26th, 2024. If you've purchased the 3D printed version previously, be sure to use the coupon that was included in your shipment for upgrading to the silicone version, valid until August 1st, 2025. 

[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
  
• 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)
• Odour-free
• Special surface treatment for reduced attraction to dust
• Logo is hidden on the inner surface rather than around the outside

[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 3D printed, flexible 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.

Note: Seal colour is randomly selected and may not match your bellows.

[*Disclaimer]

• Grinding after changing grind size or using darker roasts/oilier beans may still cause some retention.
• Achieve the best results with lighter roasted beans and at a consistent grind size setting.
• The coarser you grind, the more likely you'll achieve zero retention
• The more beans you store in the hopper, the less effective the bellows may be due to restricted airflow
• Does not include the grinder nor the stock hopper
