I recently purchased a new set of burrs for my Rancilio Rocky from a reputable vendor. What I didn’t realise was that the vendor has two offerings for the Rocky burrs, ie. genuine and non-genuine. I happened to buy the non-genuine versions without knowing. When compared side by side, they appear to be identical in every way, apart from the missing Rancilio logo on the non-genuine ones. However, it soon becomes apparent that there is a performance difference. Using the correct and identical calibration method for the grinder, whereas I was grinding on a setting of 4-5, I’m now grinding on a setting of 1, with no option to go finer. I think if you’re grinding for plunger, pour over or drip, then these non genuine burrs are acceptable, but they are no good for espresso.

Was mainly referring to lack of durability of non OEM burr-sets...

How do I recalibrate the grinder? The non-genuine burrs were touching, but the grind wasn't fine enough. Now with the genuine burrs, I'm at a finer grind setting but there are quite a few clicks to go before they touch. There is no play in the motor. Is there anything else that affects the grind other than the hopper? What I do, is wind down the burrs until they touch, then back it off a bit to align the hopper and screw it down. Is that right?

If the Rocky isn't going fine enough, it's usually because the hopper has hit the stop screw. A re-calibration involves "tweaking" the hopper/stop screw mechanism.

Amen to that, purchased a non genuine set of burrs for my Rocky to replace the originals after about 5 years of use, they lasted 6 months,replaced them with the real deal, they were still fine when I sold the machine years later.Originally posted by Dimal View PostYep, a lot of us discovered this issue the hard way.
Once bitten, twice shy. Have only used original manufacturers' items since...

Yes OK, that's right. I thought I may have been missing something else.Originally posted by JetBlack_Espresso View PostIf the Rocky isn't going fine enough, it's usually because the hopper has hit the stop screw. A re-calibration involves "tweaking" the hopper/stop screw mechanism.
