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 my 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)

 

[Optional Bundle]

For the most streamlined single dosing experience, go with the bundle, which includes:

  • This bellows
  • Switch Lock Soft Mod | Holds the front rocker switch on so you can grind hands-free and pump the bellows more easily
  • BeanGlide cover | Prevents beans from getting stuck in the hopper so you can get the whole dose ground

 

[*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

Extremely pleased

The bellows addition for my Rocky is a game changer. My wife and I like significantly different roasts and the ability to remove the remnants of the previous grind is great. Well made, fits perfectly and great quality material. Saved me from replacing my Rocky to a single dose

Very happy!

I wish this stuff was stock with my rocky grinder but it's not, so I'm incredidbly grateful for places like Introvert existing. The delivery was great, everything was packaged well and above all else it functions perfectly. Very happy!

Transformation to single doser went well. Most of the coffee is pushed out. Makes it easier to use the same amount of coffee each time.

Great upgrade for Rocky grinder

The bellows makes it so much easier to get rid of the retained ground coffee. In combination with the BeanGlide cover, I no longer have to poke beans out of the finger guard or bang the grinder to dislodge the grounds. Highly recommended if you don’t store extra beans in the hopper! Since I regularly switch between espresso and filter beans, I’ve been single-dosing for a long time. I had to cut down the hopper to fit in my space and Andrew was very helpful in deciding if that was a good idea.

Perfect fit

This bellow fits the grinder perfectly and makes getting the full quantity of beans out very simple.
