Used this on integra and duraace mechanical and DI2gl groups without any problem Easy to fit but make sure you use an 11s cassette remover tool. You can still use a 10s cassette remover but has a thicker chain whip Put some anti seize lithium grease before fitting Used it for everything commuting, sportive, bunchies and training with compact, semi and standard crancks
The trustable cassette, has use this since day one. The one thing i like about this is because very smooth & no noise while while shifting gears.
extremely happy with not only the Ultegra Cassette but also the fantastic turnaround by PBK to land it on my doorstep. I have been having issues with 'blowing up' the Dura-Ace cassettes but since moving to Ultegra I couldn't be happier. I also purchased an Ultegra chain from PBK and let's face it, the total weight difference is about the equivalent of having a hard boiled egg in your pocket...... and you get a bullet proof set up. The only downside was that I couldn't choose a 12-28T which I use with Dura-Ace and had to settle for 11-28T with the Ultegra. All-in-all, I continue to be very happy with PBK, the product range, availability, pricing and delivery is all second to none.
Great value for money. Only difference between the ultegra and dura ace cassette is the weight.
I upgraded from 10 spd 11-28 to 11 spd 11-28. This cassette fills in the large gaps at the low end.
For the price this is a great cassette, no need to go to the DA 9000 level.
