Shimano Dura-Ace Di2 SW-R9150 2-/11-speed Shifter Set

The Dura-Ace Di2 SW-R9150 shifters by Shimano suit your riding style
The Shimano Dura-Ace Di2 SW-R9150 shifters are electronic secondary shifters that can be attached anywhere on the handlebars using cable ties, for example to change gears faster when climbing in the top link position. Both shifters shift 2-speed at the front or 11-speed at the rear, whereby the configuration can be programmed via the E-Tube platform. At only 12 grams per pair, they add hardly any weight. The SW-R9150 is another option of the Dura-Ace Di2 to built to suit your riding style, whether you’re riding with round or aero handlebars.

Di2 systems are the electronic shifting systems from Shimano. They are based on the SEIS, the Shimano Electronic Intelligent System, which takes over the index shifting function from the mechanical components, only via power cables or radio signals and not via a Bowden cable. Shifting is done by simply pressing a button. This has the advantage that no great effort is required, your concentration on the ride is not disturbed and operation is easy even with cold hands. In addition, the electronic gear changes are very fast and highly precise. There is also no risk of a defective circuit due to dirty cables or other problems. You can adjust individual settings via the E-Tube Project, such as adjusting the shifting speed, the number of shifting operations per button press or the Synchro or Semi-Synchro shifting function. Shimano offers an app for this purpose. Gear maintenance and firmware updates are also done via E-Tube, with the bike connected to a PC running the appropriate E-Tube software for more extensive workshop work.
