The Dura Ace Di2 SW-R9150 shifters by Shimano suit your riding styleThe 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.

This product uses a technologically innovative, computerised shifting system based on the Di2 concept with the product designation SEIS (Shimano Electronic Intelligent System). The innovative shifting technology of the SEIS continues to be based on the Shimano Index System (SIS), whose outstanding shifting performance has proven itself over many years. The main difference between the systems is that the shifting operation is no longer carried out mechanically but electronically. The electronic shifting system has been tested over the last several years by more professional cyclists under all conceivable conditions, such as rain, mud, extreme cold, on cobblestones as well as combinations thereof.
The shifting process is carried out by simply pressing a button. No effort is required to shift gears, which has significant advantages as the rider always has a firm grip on the handlebars and can concentrate on riding without being distracted by the shifting. The shifting system allows precise and effortless shifting in all situations, even with cold hands or when the rider has fully exerted themselves. In addition, the shifting capacity can no longer be affected by dirty or stretched cables, as the shifting signal is transmitted electronically. The operating keys work in a similar way to mechanical dual-control levers, making it easy to get used to the new system.
E-Tube is a system platform for the Di2 concept (Digital Integrated Intelligence). E-Tube transmits interactive signals and supplies all electronic parts with power via " Plug & Play" connections. E-Tube is resistant to corrosion, expansion and frost and ensures low maintenance. It offers optimal flexibility for your bike. With E-Tube Project you can customise the settings of electronic components and update the firmware via Windows PC, tablet or smartphone. It provides quick and easy access to information on electronic components and provides an instant overview of system status.
