The Shimano Dura Ace CS-9100 11-Speed Cassette features titanium construction on the five largest sprockets and a carbon composite / alloy spider for high-performance at a low weight. Hyperglide tooth profiles ensure precise, reliable shifting with the Shimano 11-speed chains, and the introduction of new 11-30 gearing option means the Dura Ace R9100 group is the most versatile yet.

Claimed weight is 175 g (11-25 cassette).

High quality part

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.
