its a cassette I trust, looks like they have changed the packaging, probably due to supply chain issues
This is the third cassette & chain of these I've used for Dura-Ace. 1st set I got 9013 miles and 2nd was 8571. Proper maintenance (cleaning and lube) can extend the mileage. When the chain needs replacing, I replace the cassette. Prior to replacing I still was not experiencing any issues. Replaced chain due to recommended measurements.
I love the look and polish of Campy, but I switched to Shimano Dura-Ace years ago and haven't looked back. It is in my opinion the best high end groupset for the money. Easy to service, easy to maintain, easy to get parts. The Dura-Ace cassette is lighter than Ultegra and 105, does it really matter - to me yes it does. I have high end carbon whees and bike so I want all weight advantages I can get. This cassette with dura-ace chain and derailleur is quick, crisp shifting!
Duracesmooth as butter. Had to get an extra for my new carbon wheelset. Didnt wanna keep pulling off my cassette. I do find the 30t a nice bump for those 22% grades I never ride.
Shimano has always come out with great products and always cutting edge in technology. This cassette by far is the best cassette i've ever used, so light and gotta love that 30 gear...
