Dura Ace 10-speed cassette with superlight rigid aluminium spider and improved shifting performance.
The aluminium carrier and the 4 biggest sprockets made of titanium save weight and have a high rigidity. A better shifting performance is reached with the updated design of the gear sprockets.
The Dura Ace cassette is available in 8 different gear combinations.
Shimano 10-speed cassettes fit on Shimano 9speed cassette hubs, but a super narrow 10speed chain is needed!
Material: aluminium carrier, sprockets made of steel, 4 biggest sprockets made of titanium
