Gear Range 9-speed : 12-13-14-15-17-19-21-24-27.
Weight: 198 g.

The Dura-Ace 7700 9-speed 12x27 cassette feature three precision-made light alloy sprocket carriers that reduce weight while increasing sprocket stiffness. Dura-Ace cogs combine titanium and chrome-moly which keeps the weight down, maintains strength, and assures maximum torque response. Lightweight 9-speed sprockets provide a wider gear choice while weighing approximately the same as the previous 8-speed cluster. Dura-Ace lock-ring included.
