Shimano's Dura-Ace Down-Tube Shifters are lightweight beauties and a sweet choice for extra-light project bikes, triathlon and time-trial machines and anyone seeking the best in down-tube shifting. They are super reliable and provide precise indexed and friction shifting.
Features and Information
These shift levers come with cables.
For optimum shifting and braking, Shimano 7900 Dura-Ace components are best as a system (they're not recommended for use with previous versions of Dura-Ace).
