Shimano second shifter Dura-Ace Di2 SW-R9150

The Shimano Dura-Ace Di2 SW-R9150 is an ergonomic secondary shifter for electronic Di2 shifting systems, developed for use on the upper handlebars of road bikes. It enables shifting operations to be carried out comfortably from different grip positions - ideal for long rides, climbs or sprints where fast reactions are required. Shimano E-Tube technology allows flexible integration into the existing Di2 system and customised programming of the shifting functions. Thanks to its compact design and low weight, the shifter blends unobtrusively into the cockpit while offering maximum ease of use.

The SW-R9150 is the perfect addition for ambitious road cyclists who want maximum shifting precision and maximum flexibility when operating the handlebars - whether in races, during training or on long tours.
