Fellow Opus 2 Conical Burr Grinder
The Fellow Opus 2 is an all-purpose single-dose grinder that delivers impressive performance and features at a competitive entry level price. Coffee is ground with a set of 48mm conical steel burrs with smooth stepless grind adjustment for greater precision. Up to 100g of coffee can be ground at a time with included accessories for dosing into both manual filter devices like pour over cones and French presses as well as portafilters for espresso.
Grinding utilizes an automatic stop function to simplify the single-dosing workflow. If you're looking to go all-in with a Fellow espresso setup, the color, wood accents, and form factor of the Opus 2 are designed to be paired with the Fellow Espresso Series 1 espresso machine.
Why You Want the Opus 2
All-Purpose Grind Range
The Opus 2 is capable of all-purpose grinding and can comfortably be paired with espresso machines like the Fellow Espresso Series 1 and coffee makers like the Fellow Aiden. The 48mm conical burrs help reduce heat generation while grinding through increased efficiency and grind sizes range from cold brew coarse to espresso fine. The conical burrs, coupled with a built-in ionizer help reduce retention to near zero.
Included with the Opus 2 are a 100g catch cup for filter coffee and a 30g catch cup with 54 and 58mm portafilter adapters for espresso. The cups are designed with magnetic bases to securely "lock" in underneath the grinds chute.
Stepless Adjustment
A major improvement over the Opus Gen 1 is the Opus 2's stepless grinding adjustment. Most grinders at this price point have fixed burr movement that limit precision when changing grind size. The Opus 2's fully stepless grind adjustment unlocks much greater control over your grind to achieve better results in the cup.
The current grind setting is clearly identified with a small red tick-mark that lines up with the numbered collar to indicate your selected grind size.
Simple Workflow
The single-dose design of the Opus 2 is designed for easy operation for any amount of coffee and any brew method. Simply select your desired grind size and load up to 100g of whole bean coffee into the grinder. Once you start grinding, the Opus 2 will stop automatically once all of the coffee has been ground, allowing you to complete a grind cycle in just one push.
If you're not sure how to set your grind, the underside of the Opus 2's lid features a grind size chart so you can easily adjust to the necessary range for your brew method.

What does Tonava sell?
Treadmills and home cardio equipment: under-desk walking pads, folding treadmills, home running machines, commercial gym treadmills, curved manual treadmills and treadmill accessories. Every machine is brand-new from a trusted brand.
Which treadmill should I choose?
Walking pads suit walking and light jogging in a small space. Folding treadmills give a full running deck that packs away. Home treadmills add larger decks, stronger motors and incline training. Commercial treadmills are built for constant daily use. Curved treadmills are self-powered and favoured for sprint and interval work. Email us if you'd like help deciding.
Where do you deliver?
We deliver across the United Kingdom.
How much does delivery cost?
Delivery is free on every order, with tracking. Larger treadmills ship on a pallet or two-person service and the carrier will arrange a date with you.
Does it arrive assembled?
Most walking pads are ready to use out of the box. Larger treadmills need light assembly, such as fitting the uprights and console, and arrive with instructions and the tools required.
Are your products brand-new?
Yes. Every machine is brand-new and supplied with the manufacturer's warranty.
Can I return it?
Yes, within 30 days of delivery. Please keep the original packaging where possible, as treadmills are heavy and awkward to ship without it. Email support@tonava.com with your order number to start a return. See our Refund Policy for full details.
What if it arrives damaged?
Contact support@tonava.com as soon as possible with your order number, photos of the machine and packaging, and a short description, and we'll put it right.
