tompoland super interesting tx for the update. Was the swapping of the burrs straightforward? Is alignment taken care of with the carriers?

In terms of radial alignment it’s a little tricky as they are looser in the carriers, as for other alignment (axial), I have not thoroughly checked yet. It should be fine as the SSP burrs are accurate all around the periphery, as are the Mazzer burrs.

    DavecUK Given design of the carrier, looks like someone (cleverer and more skilled than me!) Could design and 3D print a centering cone a bit like you have for the base on a router.

    Like a spigot ring for a car wheel

    3 bits of tin foil round the edge haha

    @Cuprajake curious to know, how does the Niche Zero and Duo compare when pulled through the ACS Leva?

      In terms of taste the duo has more clarity to the shot, so better separation of flavours.

      Not to say the zero produces bad shots, and I think if that was all you knew you would be happy with it. The 83mm burrs in the major/duo just bring more to the table. They give more of the beans character

      Visually they both pull and hold together well, where are the SSP look like $hit 🤣

        JWSG A bit like any flat compared to a conical. I am a Duo tester. I deliberately have not put them together to do side by side comparisons because they are very different. You get used to something quite quickly. With the Duo when drinking non milk based even I can get a wider, cleaner range of flavours. But, I prefer darker roasted beans so when I switch back to the Zero, I detect a different profile immediately. I do not necessarily go down the road with flats are more suited to lighter roasts and conicals darker but the 2 grinders do produce different profiles. That said, with taste buds like mine who really knows!

          dfk41 Hits the nail in the head: Taste profile. After reading so much about flat vs conical vs SSP vs Unimodal vs High Uniformity vs High Speed vs Low Speed vs this vs that, although not really being in a position to compare grinders side by side, I did have he opportunity to try different grinders. And ultimately it boils down to a certain profile. It’s not that one is better than the other, but more like what appeals to your tastebuds for a certain coffee and roast style. As Cuprajake hints, if you don’t know something else exists or don’t have the opportunity to try it, I doubt you’d care, as the coffee will be good nonetheless. It’s when you have the opportunity to have different grinders sitting in the counter next to each other then you can realistic notice the difference in profile. Providing your tastebuds are up for it that is. As I mentioned on another post, with my hypersonic ultra powerful tastebuds (joke!) I couldn’t taste or point anything remarkably memorable and different between what my Niche Zero produces and what I got from Dave’s Duo. But I didn’t have them side by side either. But I bet if I had them side by side, I would be able to.

          Hmmm, that is interesting, though it doesn’t make it easier.

          I am looking for second grinder to compliment my P100. There are times where I do not wish to have the ultimate clarity but looking for more balanced and rounded cup with good volume. Also, non SSP burrs tend to be easier to manage the shots, visually at least.

            JWSG what’s in your p100? Burr wise

            If you want different then going smaller flat or conical will change that.

              Hu are a bright burr imo

                Thats for sure, looking for something different, but maybe not to the extreme end of bright.

                Hi do those who have used the Duo know if an alternative set of espresso burrs could be installed in the filter burr carrier or is the carrier different in anyway?

                I only drink espresso and long black coffee but would be interested in the ability to have alternative espresso burrs to try out and it would be nice to have two sets installed in separate carriers at once to allow easy interchange.

                  I have SSP burrs and the filter ones fit fine (without the need for shimming underneath)…I am going to go now and measure up the espresso burrs and let you know in this thread how they would fit.

                  https://coffeetime.freeflarum.com/d/1605-niche-duo-83mm-flat/291

                  If the fitting is the same as Mazzer 83mm burrs then alternative burrs should fit fine. Of course some “may” not be OK in terms of height above the edges of the carrier, but that can be dealt with using 0.1 or preferably 0.05mm shim washers at 3 points on then periphery.

                  SSP hu fit

                    Perfect - thats what I hope to do. Did they work well?

                    Will be interested in Dave’s reports about how they work out also
