ShimanoDura-Ace CS-9100 11-Speed Cassette(Return to Product Page)

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!

I have Dura Ace on both my bikes. A very smooth ride!

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.

lots of short, steep climbs and rolling hills

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.

30 cog is perfect for rolling terrain.

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...

Shimano high end parts are that , high end and a lot of companies try to copy it but shimano know there stuff. Expensive but worth what you pay
