Review by cjharrer

Shimano Dura-Ace is the standard all groupset should measure up to

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!

Have always had good wear on DuraAce cassettes

its a cassette I trust, looks like they have changed the packaging, probably due to supply chain issues

Shimano removed all plastics from their packaging early this year, and have also moved away from their glossy finish outer packaging to a more natural paper stock with a matte finish and more recycled materials.
Thank you for your feedback.

Second Time Around

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 needed a second set for my trainer and wanted to match exactly my bike to keep change over time at a minimum. Good price and high quality.

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.

Transitioning to Shimano Dura-Ace Di2 after many years on Campy mechanical. This cassette forms part of what is a very well designed and reliable drive train.
