My R9000 Dura Ace cassette fell apart after less than 5000 miles. I replaced it with this 11-30 ultegra cassette. It's about 60 grams heavier. I notice no difference between the two cassettes. Shifting is very smooth and quiet. This is a great buy.

Genuine Shimano cassette. I’m using this on my gravel bike paired with Ultegra chain and carbon wheels. I like the tighter gear spacing compared to a 32-12. I might suffer a bit more on steep hills but 99.9% of my riding is on the flats and some rollers.

Ultegra cassettes have always been good. I have the both 11-28T and 11-30T. I like that the 11-15 are 1T increment so you can really dial in your cadence. Then from 15-25 are only 2ts apart and from 25-28 are 3t apart. You can really fine tune your preference of pedaling and cruising speed. The weight is also good 251 grams for 11-28T. big improvement when I upgraded from SRAM 10speed to Ultegra 11speed. Of course, I had to change all my shifters and derailleurs to Ultegra. Someone recommended I change the chains every 1k though to make this cassette last longer.

Rather than waiting for a replacement from the Shimano Ultegra recall I bought this replacement so I could continue to ride my bike. This works perfectly and was easy to install

Is excellent for long days riding at a high and comfortable cadence. I installed it on a Scott Addict Team Issue which came with a 11-25 cassette combined with a 54/36 at tbe front. With this cassette, the Addict feels like my Cervelo Caledonia, confortable and easier on my 57 years old knees. Just had to replace the rear derailleur for a medium size, the original small one shifts no problems BUT, the mechanical ratio or diameter doesn't change. Therefore, I couldn't feel any change through the different cogs. Until I replaced the derailleur as well.

The r8000 is only 47 grams lighter than my factory r7000 (105) cassette but shitting felt so much smoother. My bike came with Ultegra front and rear derailleurs but they gave me 105 cassette because it is more durable. When I bought a new pair of carbon wheelset, I bought this r8000 cassette and loving it. The shifting is smooth even in the middle of a hill climb. Worth every penny and Competitive Cyclist had it delivered on time and no damage on the package. I will probably buy another r8000 to permanently replace my r7000 on my training wheel.

Attention, il s'agit bien d'un modèle de cassettes à 11vitesses et non à 8 vitesses, comme c'est présenté dans l'annonce. Ce modèle cs R8000 est bien conforme à mes attentes, car j'avais compris qu'il n'existe pas de modèle 8 vitesses en Shimano R8000
