Bellows Upgrade for Rancilio Rocky For Lower Retention

Achieve an even lower retention on every grind with your Rancilio Rocky with this 3D printed flexible bellows, up to 0.0g* (+/- 0.5g). It fits in between the stock hopper and stock lid and transforms it into a blower, enabling you to push all of those lingering grounds out.

[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
  
• Super easy installation takes less than a minute
• Ultra soft construction for an effortless pumping action
• No tools necessary for installation
• No warranty-voiding modifications needed
• Zero contact between bellows and beans each time you dose

[Compatibility]

• Rancilio Rocky (Doserless)
  
• Works optimally with our Switch Lock Soft Mod (Sold Separately)

[*Disclaimer]

• 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.
• Retention varies more right after cleaning the inside of the grinder
• Finer grinds may result in more retention, and coarser grinds less retention.
• Does not include the grinder nor the stock hopper
