Dura-Ace SL-BS79 Double/Triple 10-Speed Bar End Shifters

Introducing the Shimano Dura - Ace SL - BS79 10 - Speed Double/Triple Bar End Shifters. The right - side (rear) shifter offers 10 - Speed index - only shifting, while the left - side (front) provides 2/3 - Speed options. All bar - end road shifters produced after November 2008 fit a 19 - 22mm I.D. spec range. These shifters are compatible with Shimano Road rear and front derailleurs. They can be mounted at the bar end or on the downtube. With 10 drivetrain speeds and an end type suitable for Shimano/SRAM, they're perfect for TT and Time Trial setups.

Using these shifters is easy. For the rear shifting, just use the right - side shifter to change through the 10 speeds. For the front, use the left - side shifter to switch between 2 or 3 speeds. When mounting, make sure to check if your bike's bar end or downtube fits the 19 - 22mm I.D. spec. Keep the shifters clean by wiping them regularly with a dry cloth. Avoid exposing them to extreme moisture or dirt. If you notice any issues with shifting, check the connection with the derailleurs. Also, make sure to use them only with Shimano Road derailleurs for best performance.
