Fellow Ode Burrs: Understanding the Difference Between Gen 1, Gen 2, and SSP Upgrades

If you already own a Fellow Ode or you're deciding between generations, the burrs are the single most important factor in how the grinder performs. Fellow changed the burr set between Gen 1 and Gen 2, and a third-party upgrade from SSP exists that changes the picture again. This article breaks down each option, what the differences mean in practice, and whether upgrading is worth the cost if you already own a Gen 1.

The short version: the Gen 2 SSP Unimodal burrs grind meaningfully better than the original Gen 1 burrs for both filter and espresso. The aftermarket SSP upgrade for Gen 1 owners costs around $130 to $150 and delivers most of that same improvement.

The Gen 1 Fellow Ode Burrs

The original Ode launched in 2020 with a set of 64mm flat burrs that Fellow designed in-house. These burrs were optimized for filter coffee. The particle size distribution they produced was good for pour-over, AeroPress, and batch brew, where grind consistency at medium-coarse settings matters most.

The problem that users discovered quickly: the Gen 1 burrs produced a lot of boulders, meaning oversized particles, at coarser settings. For a French press or coarse filter, this shows up as a less uniform extraction where the coarser particles underextract while finer ones overextract. Cups from the Gen 1 Ode at coarse settings could taste muddy or uneven compared to grinders like the Wilfa Svart or Baratza Encore at similar price points.

At finer settings for espresso, the Gen 1 burrs had a different problem. The grind-by-weight (GBW) issues aside, the particle distribution wasn't ideal for espresso extraction. Shots were harder to dial in and less expressive than what you'd get from a grinder designed for espresso at a similar price.

Fellow heard the feedback and redesigned the burrs for Gen 2.

The Gen 2 SSP Unimodal Burrs

For the Gen 2 Ode (released 2022), Fellow partnered with SSP, a South Korean burr manufacturer with a strong reputation in the specialty coffee community. The burrs installed in the Gen 2 are SSP's "Unimodal" profile, sometimes called "High Uniformity" burrs.

Unimodal refers to the particle size distribution the burrs produce. Where the Gen 1 burrs created a spread of particle sizes with peaks at multiple sizes, the SSP Unimodal burrs produce a more single-peaked distribution with fewer outlier particles. In practice, this means more even extraction and a cleaner cup.

The Gen 2 also came with an updated grind range that pushed further into espresso territory. This opened up the Ode for home espresso use in a way the Gen 1 couldn't really support.

How Much Difference Do They Make?

Side-by-side, the Gen 2 produces noticeably cleaner pour-over. Cups have better clarity and more defined flavor separation. The difference is real and noticeable without needing to be a trained cupper.

For espresso, the Gen 2 goes from "technically possible but frustrating" to "genuinely functional." You can pull decent shots on the Gen 2 that you'd actually enjoy, which was a stretch on the Gen 1.

The Gen 2 doesn't close the gap with dedicated espresso grinders, though. For espresso first and foremost, a Niche Zero, Eureka Specialita, or Baratza Sette 270 will still outperform it for shot quality and dialing-in ease.

The SSP Aftermarket Upgrade for Gen 1 Owners

SSP sells replacement burrs for the Gen 1 Ode in a few profiles. The Unimodal (High Uniformity) burrs match what Fellow installed in the Gen 2. The "Multipurpose" burrs are a different profile designed to handle both espresso and filter even better than the Unimodal.

Installation requires disassembling the grinder, which involves removing the top burr carrier and inner burr. It's not particularly difficult and many home baristas have done it with no prior grinder repair experience. Fellow's design makes the burrs accessible, which is a genuine user-friendly decision.

Cost is around $130 to $150 for the SSP Unimodal set, and around $150 to $180 for the Multipurpose profile. Given that a Gen 2 Ode costs around $345 and a Gen 1 can be found used for $150 to $200, the math on upgrading a used Gen 1 is appealing.

Which SSP Profile to Choose

If you primarily drink filter coffee, the Unimodal profile is the right choice. It matches the Gen 2 performance and delivers excellent results for pour-over, AeroPress, and batch brew.

If you drink both espresso and filter and want the single Ode to handle both seriously, the Multipurpose (also called "All-Purpose" in some listings) profile is worth the small price premium. It handles espresso slightly better and filter very well.

The Gen 2 Ode vs. A Burr-Upgraded Gen 1

This is the practical question for anyone deciding between buying a Gen 2 and buying a used Gen 1 and upgrading the burrs.

The Gen 2 includes the SSP burrs plus the updated grind range adjustment. The extended espresso range on the Gen 2 isn't available on the Gen 1 through a burr swap alone. The Gen 2's adjustment collar has more travel on the fine end.

For a filter-focused setup, a used Gen 1 with SSP Unimodal burrs is essentially equivalent to a Gen 2 and often cheaper total. For a setup where espresso matters, the Gen 2's extended range is useful and worth the premium.

How Burr Break-In Affects Performance

New burrs, whether from Fellow or SSP, need break-in. During the first 10 to 20 hours of grinding, metal burrs are wearing in and producing some metallic particles that affect cup flavor. Most users notice the grinder performs better after break-in than when new.

The common approach is to grind cheap coffee through the new burrs for a few sessions before using your good beans. Some users do a "burr seasoning" by grinding through a full bag of inexpensive beans specifically to break in the burrs. It's not strictly necessary but does speed up the process.

After break-in, burr performance stabilizes and stays consistent for a long time. The 64mm burrs in the Ode are designed to last hundreds of pounds of coffee before needing replacement.

Cleaning and Maintaining the Burrs

Flat burrs in the Ode need periodic cleaning to maintain performance. Coffee oils build up on the burr surface and start affecting grind quality, typically showing up as a stale, muted flavor in the cup.

Fellow recommends cleaning the Ode every 7 to 10 pounds of coffee. The top burr is accessible without tools on most versions, making it easy to brush clean. A thorough cleaning with a burr brush takes about 5 minutes.

If you're switching between very different roast levels, a quick brush before the transition helps clear oils from darker roasts that can affect the flavor of lighter ones.

FAQ

Can I put Gen 2 SSP burrs in a Gen 1 Ode?

Yes. The Gen 2 and Gen 1 use the same burr mounting. SSP burrs sold for the Ode fit both generations. The only thing you won't get from the swap is the Gen 2's extended grind range on the fine end, which requires the updated adjustment collar.

Do the SSP Multipurpose burrs make the Ode a real espresso grinder?

They make it a better espresso grinder than stock. Whether it qualifies as a "real" espresso grinder depends on your standard. It's capable of producing good shots, but dedicated espresso grinders at similar price points still have an edge for dialing consistency and shot expressiveness.

How do I know if my Gen 1 Ode burrs need replacing?

Signs include visible chips or wear on the burr edge, increasing amounts of fines in the output, and a noticeable degradation in cup clarity over time. For typical home use, original burrs last many years before needing replacement.

Are there other aftermarket burrs besides SSP for the Ode?

A few other options exist, but SSP has the strongest track record in the specialty coffee community for the Ode form factor. Check the home espresso subreddit for the latest community testing if you want to compare profiles.

Bottom Line

The burr choice makes the Fellow Ode a very different grinder depending on which set you're running. The Gen 1 stock burrs are adequate for filter coffee but limited. The SSP Unimodal burrs in the Gen 2 are a real improvement that makes the Ode competitive in its price class.

If you own a Gen 1, the SSP upgrade is worth it if you care about cup quality. If you're buying new, get the Gen 2. The extra cost over a used Gen 1 plus upgrade kit is usually small and you avoid the installation step.
